PREFACE,

gue are not many, if any, homes in the country or suburbs
of large cities where fish culture could not be indulged in,
either as an agreeable pastime or with a view of realizing an
income from it.

Being accidentally drawn into the culture of ornamental fish
through a genuine love of Natural History, I have, for the past
ten years, given it my exclusive attention.

The originality of the method I describe in the following pages
I claim as my own, and it has been my earnest endeavor to speak
plainly and to the point, giving the full results of my long
experience, not intentionally withholding any facts or secrets that
would in any way have a bearing upon the success of the business.

This method has the decided advantage of applying equally to
the culture of goldfish, no matter upon what scale it is carried on,
whether the establishment is intended to produce hundreds of
thousands of fish annually, or be engaged in with limited means
by the deserving widow or invalid who wishes to add something to
a restricted income.

With these objects in view, and to promote a more thorough
knowledge of the goldfish, as well as to stimulate the study of
Natural History, I have made every exertion, and should my
efforts meet with the approval of an intelligent public, I shall
consider that I have not labored in vain.

PREFACE TO THE NEW EDITION.

Manyfold indeed were the acknowledgments of the useful-
ness of this little volume. It has been translated abroad in four
different languages, and it is to-day used all over the civilized
world and acknowledged authority on the subject upon which it
treats. The scores of letters which I received from all parts of
the world, applauding my method, are proof that the volume as
it is, is a reliable guide,

Only a few important additions, but no corrections, appeared
to be necessary for this new edition.

THE GOLDFISH AND ITS VARIETIES.
Cuapter I.

“Every man is a valuable member of society,

who, by his observations, researches, and

experiments, procures knowledge for men”
SMITHSON,

THE HISTORY OF THE GOLDFISH.

 

Long before the principles upon which the success of an aqua-
rium are based were understood, goldfish were kept and tenderly
cared for, merely because they are beautiful, and besides being in a
sense pets, upon which to lavish much solicitude and attention,
served the purpose of an animated ornament, than which it is diffi-
cult to find a more beautiful and desirable substitute. The very fact
of their being denizens of a different element than that in which
the most familiar domestic animals and pets live, served to surround
them with a halo of fascination that prompted their admirers to
expend upon them any amount of time and pains to keep them in a
flourishing condition, and ever ready to be displayed before the
chosen guest in the household.

Their wonderful tenacity of life, the gorgeous colors in which
they are clothed, both contributed to make them adapted to life in
the aquarium and grace the elaborate structures that were framed
for the express purpose of displaying them to the best advantage.

The goldfish, we are told, like many other things, originated in

China, though, so far as this is concerned, its history is involved in
5
6 THE GOLDFISH AND ITS CULTURE.

much obscurity. The first mention we find of it is in the ‘‘ Arabian
Nights’ Entertainments,” in the story of the Fisherman and the Genii,
a story, which like those accompanying it, is of Persian origin. It
is, however, frequently represented in the old Chinese paintings, and
appears to have been held in great esteem, insomuch as several of
the ancient and distinguished families among the Chinese carried it
as a component part of the family coat of arms, or as an ornament
upon their armor, In short, the goldfish has always been looked
ypon as a kind of superior being among the finny tribe, the ancients
even dedicating it to their well-beloved goddess, Venus.

In China, even at the present day, the goldfish enjoys the admi-
ration of all, and may be seen in almost every house, inhabiting a
richly-decorated China bowl, or disporting itself in lakelets in the
gardens, made for its especial care and enjoyment. They are alike
admired and beloved from the august Emperor on his throne of
State down to the most humble and impoverished peasant in the
realm, all seeing in it an object worthy of care, and, it might be said,
of love. So intense is the fondness for the goldfish in the land of
Chinamen that it has begotten a study of them and their habits, that
amounts to a science, All the resources of the knowledge of them,
thus gained, have been exhausted in the production of new varieties
by the crossing of different species, and with marked success.

In the larger cities the fish are regularly brought to market and
offered for sale, very much as our florists offer their flowers and
plants. For that purpose they are separated into pairs, and placed
in little vessels made of bamboo, and, together with some bit of
water plant, are sold to ready and ever eager purchasers; the prices
ranging according to the variety and perfection of the specimens.

The mandarin, in person, may sometimes be seen in the markets
buying fish for his aquaria, which, indeed, are often made of carved
ivory, and inlaid with gold. These purchases he makes with the

same relish and delight that one takes in making a new and valuable
addition to his conservatory.

The most choice and beautiful varieties are obtained from a lake
in the province of Che-Kyang.

The first introduction of the goldfish into Europe is variously
dated, the years 1611, 1691 and 1728, A. D., each having claims for
that honor; it may be said also that the variety introduced was the
poorest and cheapest the Chinese had.

The first seen in France, however, were those imported for the
famous Madame de Pompadour. Soon afterwards they became quite
common, as it was found that they throve well in the waters of South-
ern Europe, especially in Portugal, where they sprang from a few
small fish, said to have escaped from a vessel newly arrived from
China. In that country they are now considered a delicacy for the
table. It was not long until several streams in the neighborhood of
Lisbon absolutely swarmed with them, and it is from this source that
all Europe became stocked with them. From Europe the fish were
brought to America, and quickly won their way into favor. For the last
forty years, perhaps, these fish have become wild in the United States.
Some having accidentally escaped into open waters, they soon made
themselves at home, became thoroughly acclimated, and in conse-
quence the goldfish has been quoted by several authors as a native
American fish. It is true that, having been born here, they are in
one sense native, but are of native in the sense, origin, as having
originated here. Living thus in a wild state, the fish has greatly
degenerated from the original standard. Through the efforts of
the late Admiral Dan. Ammen, U.S.N., the cultivation of the
goldfish in the United States has received a new impulse.

This gentleman, but a few years ago, brought from Japan a num-
ber of specimens of the choicest varieties which have since been

reproduced with marked success.
THE GOLDFISH AND ITS CULTURE.

ce

The annual sale of goldfish in this country at the present day
may be estimated at two millions, and of a value of $300,000.

Although this number is greatly exceeded by Europe, ours are
their superior in quality, and the wholesale prices received for them
are from one hundred to five hundred per centum higher than those
paid to European culturists, who are at present, in connection
with Japan, endeavoring to compete in.the American market.
CHAPTER II.

THE COMMON GOLDFISH.

(Carassius auratus.)

DER GOLDFISCH. LE POISSON ROUGE,

The goldfish belongs to the carp-family, and by some authors is
called Cyprinus auratus, which means gold-carp. A thorough inves-
tigation of the subject has led the author to the adoption of the
name used in the heading, which is also used by some other authors.
Besides being more correct, according to the anatomical structure of
the fish, is more distinguishing, as there exists a variety of the
European food-carp, known as the golden carp, or cyprinus aureus,
which is in no ways identical with the goldfish cavassius auratus.

The body of the fish is elongated, compressed upon the sides
and entirely covered with a coat of uniformly-sized scales.

The head is short, naked, that is, without scales; the lips well
developed and without barbles.

The color is generally an orange-yellow with a golden hue,
sometimes marked with white or black; the abdomen may be either
white or yellowish.

The name of the entire family, of course, had its origin in the
prevailing golden color of the species first introduced into Europe.

The dorsal fin is long, reaching from the middle of the back

nearly to the tail; specimens with a short dorsal fin are deformed.
9
Io THE GOLDFISH AND ITS CULTURE.

They may sometimes have a divided tail, giving to them, if viewed
from behind, the shape of a reversed letter ‘‘ Y,”

The size of the goldfish varies according to the locality in which
they are raised, and the circumstances surrounding them, it being
possible for them to attain a length of eighteen inches and a height
of six inches. It is said that they may live to be a hundred years
old, but this may be an exaggeration.

Goldfish enjoy a warm temperature, in bodies of water without
a current; just such water as ponds afford suit them best, though
they will make themselves at home in streams and multiply exceed-
ingly. They are very hardy, and thrive well under circumstances
that would be fatal to many other fish, this quality particularly
adapting them for life in the aquarium, specimens having been
successfully kept in this way, in good condition and health, from ten
to sixteen years. So far as food is concerned, the goldfish will feed
upon almost all kinds of vegetable matter, insects, worms, etc., even
preying upon small fish, and devouring its own spawn and young.
The food is taken in by a sucking motion of the lips; the mouth
being toothless, as in all carps, the mastication is accomplished by a
few bony tubercles situated in the throat.

In the spring or summer following the one in which they were
‘ hatched, goldfish attain their maturity. The size of the fish has
nothing whatever to do with the ability to spawn, though a large fish
will deposit more eggs than a small one. Asan instance, goldfish
one inch in length, nine months old, spawned in an aquarium kept
in a parlor; all the eggs hatched and the young grew up. In the
spring of that year, when the temperature of the water rises above
60° F., they become lively and vivacious, losing all timidity and
precaution, so that they easily fall a prey to their many enemies.

Two, three or more male fish follow a female, chasing her to
some shallow place where there is an abundance of water-plants.
THE GOLDFISH AND ITS CULTURE. II

They lash the water in a lively way, twisting the posterior portion of
their bodies energetically and shooting through the water near its
surface with short tremulous movements of the fins. At places they
gather together in a compact mass, one tumbling over the other.
This is the moment when the female drops her eggs, which are
immediately impregnated by the males.

This process is repeated throughout the summer, with intervals
of rest during the hottest period. The eggs are of the size of a pin-
head, and may be either semi-transparent, yellow.sh, or brilliant
yellow in color. Whether this difference in the color of the eggs
has anything to do with the coloring the fish will acquire after it is
hatched still remains an open question. With the eggs of the trout
the case is different, for the culturist can predict the color of the
flesh of the fish when grown up; it is possible that this may also
apply to the goldfish. The eggs are covered with some adhesive
substance, mucus probably, and adhere to anything they happen to
touch. The water-plants in the immediate vicinity of the place
where the fish have been rolling about will, upon examination, be
found covered very profusely with them.

The young are hatched out in from two to six days, the period of
incubation being determined by the temperature of the water and
the condition of the weather. Direct sunlight has the effect of
hastening the process.

During the first few days the young fish are not able to move
about much; they hang or lay about among the water-plants, obtain-
ing subsistence from their yolk-bag, but as soon as this is absorbed
they swim around on the search of something to eat.

The color of the skin of young goldfish is at first silvery gray, but
at an age of six weeks this color begins to change, becoming darker
and assuming a cloudy appearance, finally taking on the permanent
color. The whole process is sometimes completed in two days,
12 THE GOLDFISH AND ITS CULTURE.

though in some instances it is deferred until the following spring.
The perfection and rapidity of the coloring process depend upon
several causes, foremost among which is the proper selection of
specimens from which to breed.

This is a very important consideration, in truth, the prime factor

upon which hinges the character of the result.

When hatched, the young fish are further subjected to modifica-
tion by their surroundings, the temperature of the water, its depth,
quality, etc., all exercising more or less influence.

The complete result of the breeding, so far as the coloring is
concerned, can not be seen until the change has taken place, when
any errors that have been made are at once apparent. Those fish
that have failed to receive any coloring are then called silver-fish ;
should they have turned milky white (albinos), they are known as
pearl-fish.

The young, when kept in warm ponds—this means that the
ponds are so located that the sun can warm them thoroughly—may
grow six inches long in four months. As a general thing, however,
the length reached in that time is from two and a half to three
inches.

In connection with this may be mentioned that all the young of
the same spawning do not grow at an equal rate, some few doubling
the average size, while others fail to reach it. The latter are then
known as dwarf goldfish, and are much in demand for small aquaria.

Deformities occur oftener in this family of fishes than in any
other. Specimens minus a dorsal, anal, or even caudal fin, are
frequent; rarer are those destitute of scales or minus an eye or with
a lob-sided mouth.

From the habit of the goldfish to seek its nourishment on the

bottom of the pond in which it lives, and to its careless sluggishness,
THE GOLDFISH AND ITS CULTURE. 13

caused by its voracious appetite, the goldfish, especially in its
younger days, falls the victim of innumerable enemies,

In fact, so easy is it to destroy them, that anything else living in
its company in the pond and of sufficient strength to master it, may
be set down as its enemy.

When arrived at maturity its peculiar mode of reproduction
renders it a welcome prey to enemies that do not live in water. It
is likewise subjected to diseases of various kinds, and considering all
that, it may be said that it is a mere accident when goldfish multiply
to any considerable extent without the protection of man, or that
the circumstances under which they increased were exceptionally
favorable.
CHaPTER III.

JAPANESE GOLDFISHES.

(Carassius japonicus.)
JAPANISCHE GOLDFISCHE, POISSON D’ORIENT.

In introducing this variety of fish to the attention of the reader,
it may be said that the description of the mode of reproduction,
habits, etc., regarding the common goldfish, equally apply to the
Japanese and Chinese varieties, as they are members of the same
family, differing only in shape and color.

The Japanese specify the goldfish by the shape of the body and
that of the fins, the coloring in most species being the same. The
prevailing colors are vermillion, gold and white, if indeed the last
can be called a color.

The Japanese classification being rather complicated, the species’
names will be omitted for convenience sake, and the fish described
in the manner others have been, though at the same time retaining
the foreign nomenclature.

THE TELESCOPE.

This fish is indeed an odd looking affair. The body is spherical
very much like that of a frog-tadpole, and covered, as all goldfishes

are, with medium-sized scales. The fins, are very delicate in struc-
Mu

ture; the anal fin mostly absent; the caudal fin is double, very large
and deeply divided. The eyes are large and project forward, having
the appearance of a small telescope adjusted to the eye (see illustra-
tion), from this the fish received the name it bears. To make the

 

THE TELESCOPE.

eyes more prominent the Japanese culturist resorts to an ingenious
device. He places the young fish in small dark-glass vessels shaped
for the purpose, and which obliges the fish to look constantly in but
one direction.

The color of the fish may be either vermillion, white or part of
both, the markings in that case being very beautiful. The body of
the fish is all out of proportion to the size of the fins, and in conse-
quence propulsion is a difficult matter.

In spawning, thé male rolls the female about among the stones in
a most pitiful manner, sometimes for days together; this is an effort
of the male to assist in the extrusion of the eggs. When spawned
the eggs attach themselves to the stones and other substantial objects
rather than to water-plants, probably because it is amongst the
stones that the extrusion takes place.

When the young are first hatched, they appear exactly like the
common goldfish. They rest upon the water-plants or other sup-
ports for a couple of days, at the end of which time the yolk-bag is
absorbed; then commences the struggle for existence. The double
16 THE GOLDFISH AND ITS CULTURE.

tail, which is even then large enough to be distinguished, hinders
the tiny creatures (but one-quarter of an inch in length) in their
movements in the water. Should they find sufficient food to make a
bountiful meal, matters become still worse, they lose their balance
and can not go at all until digestion is completed, in the meanwhile
falling an easy and welcome prey to numerous enemies.

For this reason, which is the main one, and because the fish is
very difficult to propagate, it is exceedingly rare, even in Japan.

When mature, the telescope fish is about the size of a man’s fist.

THE FRINGE-TAIL.

The body of the fringe-tail is short, egg-shaped and slightly com-
pressed; the eyes normal, but very variable in the color of the iris,
which is that curtain in the anterior portion of the eye that by its
contraction and dilation, regulates the quantity of light that enters
the optic, In this fish the color of the iris may be any color, except-
ing green only, in different individuals.

The fins are large and of very fine structure; the anal fin is
double, while the caudal may be either double, treble or quadruple,
as the case may be, and is larger than the body, drooping very grace-
fully. (See illustration.) These special characteristics, among all the
fancy varieties, are not fully developed until the second year. In
the coloring of the body and fins this fish is not surpassed by any
other, making one of the most valuable and desirable objects for the
aquarium. ‘There are specimens the back and sides of which are
deep vermillion, the abdomen, throat and eyes of rich gold, while
all the fins are milk white. Others again will be found presenting a
rich vermillion on that part of the body forward of the dorsal fin
including the throat, part of the abdomen, and the respective fins,
while all back of that is pure white. Some there are with body all

white, the fins red, and we versa; others pearly, dotted with irregu-
larly shaped pink spots, the eyes being blue; again, the entire fish
will be white, the only touch of color being the deep red of the large
eyes. In fact, it is impossible within the limits of this sketch to
enumerate the endless variety of the markings to be seen, and one

can only get an adequate idea by examining a large number.

 

THE FRINGE-TAIL.

Strange as it may seem, this beautiful species of fish was nearly lost
to this country through the caprice of private individuals who
happened, or rather were lucky enough, to possess perfect specimens,
and were unwilling that others should enjoy the possession of the like.

But fortunately the late Mrs. Larz Anderson of Cincinnati, O.,

a lady both generous and appreciative, rather than that the stock
18 THE GOLDFISH AND ITS CULTURE.

should die out, loaned to the author for the purpose of reproduction
several fine specimens she had recently obtained. The pure stock
may now be considered secure for the future. In evidence of the
extreme beauty of the species, it may be stated that private parties
paid for fine specimens twenty times the weight of the fish in gold.

What has been said about the difficulty of raising telescope fish,
may with almost equal propriety be repeated for the fringe-tail.
Unlike the former, the latter fish spawns against aquatic plants, the
extrusion of the eggs not being so difficult.

THE FANTAIL.

The body is elongated and compressed ‘on the sides; the head
pointed ; the fins are short and stout, the anal sometimes double, and
occasionally found wanting. The caudal fin is comparatively short,
is double, with the upper edges grown together; it is sometimes erect
like that of the fantail pigeon (see frontispiece), or projects horizon-
tally. The colors are mostly vermillion and white; in some cases
the whole body is white, with the exception of the abdomen, this
being golden; in others the body is dark red, the belly also golden.
The color of the eyes is variable.

It may be mentioned here as an advantage of the double-tailed
fish, that they are unable to jump out of the water. This fact is
undoubtedly one to be appreciated by those keeping an aquarium.

THE COMET.

This is a noble looking fish, and greatly resembles the fantail.
Its body is slender, the fins very large and of fine structure; the
caudal fin is single and deeply divided. The coloring is identical

with the preceding.
THE GOLDFISH AND ITS CULTURE. 19

THE NYMPH.

The body of this species is oblong, and much compressed on the
sides; the head is short, and fins normal. The color varies from a
light to a deep vermillion, sometimes white; a background of white
beautifully dotted with crimson, the throat golden, makes a magnifi-
cent combination that is very ornamental indeed.

The sub-varieties of this are the Ramsnose and the Hognose.

THE RAMSNOSE.

That part of the body of this fish from the mouth to the dorsal
fin forms a bow, like the forehead ot a ram, this feature giving the
fish its name. The lower part of the body from the mouth to the
tail continues a straight line.

THE HOGNOSE.

The peculiarity of this fish is just the reverse, concaved, greatly
resembling the head ot a fat hog.

All of the goldfish described above do not attain a very great size,
seldom attaining a length of more than eight inches.

CHINESE GOLDFISHES.
(Carassius orientalis )

CHINESISCHE GOLDFISCHE. PoIssON D'ORIENT.

The Ghinese species of goldfish differ more from each other in
color than in the shape of the body and fins, the contrary being the
dominant characteristic of the Japanese species, described above.

So startling are these colors that one is almost immediately
reminded of the story in the ‘‘Arabian Nights’ Entertainments”
of the enchanted lake, the fish in which were of four colors, yellow,
blue, red and white, and were people of four races, who had in
some way incurred the displeasure of a genius, who, in revenge,
had thus transformed them.

The Chinese reckon seven distinct species, each with its sub-
varieties, the most of them very beautiful indeed. Of the species
King-Yu, the variety called

THE MOTTLED BEAUTY

is very remarkable. Beneath, the fish is simply silvered, but on the
back and sides it is mottled with rich hues of blue, yellow, black and
rose, the latter color deepening into pure crimson at the gills.

Along the ridge of the back, especially near the tail, the black
20
THE GOLDFISH AND ITS CULTURE. 21

becomes very intense, and has the rich appearance of a piece of
Lyons velvet.
Another of the same species is

THE SUPERB.

This magnificent fish, when fully developed, is nearly fifteen
inches long. The under part is silvered like the preceding, but the
back, which is remarkably broad, is splendidly varied with scarlet and
black, the scales being delicately edged with a metallic gold color.

THE SMALL BLUE.

This, like the others, is also silvery on the abdomen, but which,
however, is delicately flushed with pale rose. The whole of the
sides and back are of a rich azure, which shines with a metallic
luster.

THE MOOR, OR DARKEY,
is another distinct variety, and is a large fish. The back and sides

are very nearly black, which becomes violet underneath. All of the
scales are edged with a red-toned bronze.

THE PIE-BALD.
Species Ouen- Yu.

This is a very beautiful variety, the ground color of which isa
delicate flesh tint, and upon which there are large patches of rich
brown, very much like the markings of a pie-bald horse.

THE RUBY.
Species Nin-eubk- Yu.
This is a fish of exquisite beauty, being of a delicate semi-opaque,
violet crimson, gradually shading off to pale rose underneath.
A peculiarly fine variety of this species is
22) THE GOLDFISH AND ITS CULTURE.
THE RED-FIN,

the body of which is a delicate azure, while the head, tail and fins

are an intense scarlet.

THE TUMBLER.
Species Kin-teon - Yu.

This is a remarkable fish, and one that seems quite distinct.
The head and tail are bent upward, giving to the entire fish the form
of a crescent.

When swimming it has the habit of throwing itself over and over
in the same manner that tumbler pigeons do when flying. The color
of the fish is a magnificent blue flushed with orange making a gor-
geous display.

THE ELEGANT.

This is a variety of the species Ouen-Yu, or ‘‘ lettered kind,” so
named because the streaky markings are not altogether unlike
Chinese characters.

It is of a pure white sparingly dashed with patches of pearly
pink on the body, and having some exquisite letter-like markings or
tracings about the head and tail. Another variety of the species is
rich scarlet, shading off to black on the back, in the midst of which
is a large cross of pure white having two transverse bands like the
Cross of Lorraine, by which name the author thinks proper to desig-
nate it.

THE PONDS AND THEIR CONSTRUCTION.

ABOUT FISH-PONDS IN GENERAL.

 

A basin of water in the open air, so arranged or constructed that
the water may be drawn off at any desired time, is called a pond. A
body of water not under control, in the full sense of the word, is
usually known as a pool ora lake. The dimension of such body of
water does not necessarily regulate the name applied to it, as for
instance, a pond may either be but a few feet in length and breadth,
or it may cover an estate of hundreds of acres in extent, just as the
requirements of the case may be.

In countries far removed from the sea-shore, or any other natural
source from which fish may be obtained in large quantities, the
necessity arises for supplying the want by some means or other.
This can only be done by cultivating them on a large scale, and in
quantities sufficient to meet the demands of a steady market. The
cultivation of fish for the purpose of food has been carried on for
many generations, and so far back as the Middle Ages considerable
attention was given by the monks to pond culture, in order that they
might havea reliable source from which to procure fish during lent.

From those days virtually dates the systematic culture of fish in

waters that are thoroughly under control,
25
26 THE GOLDFISH AND ITS CULTURE.

At that time means of transportation were meager and very slow,
so that the cultivation of fish in the interior was a prime necessity,
yet notwithstanding the rapid transit on the railroad of the present
time, putting inland places in close connection with the ocean and
other natural fish reservoirs, pond culture may be and is carried on
with both success and profit. Though the railroad has made the salt-
water fish a great rival of that cultivated in fresh water, the latter
nevertheless has the advantage of always being marketable and close
at hand,

To so successful a degree has pond culture arrived at the present
day, that one is enabled to propagate the scaly tribe in quantities
without limit.

The fish that was principally, if not to say exclusively, cultivated
in ponds in former days, was the famous German carp; the estab-
lishments founded three and even four centuries ago being still in
successful operation, and may at any time be seen in various parts of
Austria and Germany. So thoroughly has the industry been studied
that it might almost be dignified with the name of ascience. The
profits arising from it are enormous, and it may be that interest has
had something, if not very much, to do with the pond culture as it is
now carried on.

To give the reader an idea of its extent in those countries, it may
be said that the carp ponds belonging to the manor of Wittengau
number 250, and cover an area of 22,000 acres, the annual yield of
fish from which is one-half million of pounds. Similar establish-
ments are found on the manor Kénigswartha, in Upper Silesia, with
205 ponds, covering 9,000 acres; the manor Peitz-Cottbus (Branden-
burgh) with 72 ponds, covering 5,600 acres. These and many other
large establishments, to say nothing of thousands of ponds scattered
all over Central Europe, give ample evidence that the industry is one
of magnitude and importance.
THE GOLDFISH AND ITS CULTURE. 27

In this country the cutting down of timber, the draining of the
land, and the establishment of new industries have no doubt greatly
increased the value of the soil, but have also influenced the decline
in the productiveness of the water.

This is a matter of serious importance, and one which is already
claiming the attention of intelligent journalists who see the necessity
of fighting the evil ere the remedy is beyond our reach. In fact, the
fish industry of the country is one of national interest, and was, not
many years ago, the cause of diplomatic difficulty between England
and the United States, putting the latter to the expense of millions of
money before the matter was satisfactorily adjusted. In view of these
facts it will not be long before the necessity of cultivating fish for the
market will make itself felt, just as it is in Europe to-day.

The consumption of food-fish, of course, increases with the
increase of population, while on the other hand, for reasons given,
the supply is rapidly decreasing in quantity and quality. Besides the
creeks and rivers are now becoming the sewers into which the wash-
ings and dirt of the nation are poured, and the gradual destruction
of our fish is consequently taking place right under our eyes.

In the author’s opinion, the decrease of our fish is not so much
due to the use of small mesh seines, as many pretend, as it is to the
increased demand for fish as food. The destruction caused by a few
careless fishermen is more than counter-balanced by turtle-hunters
and snake-killing boys, the one making it a business, the other
engaging in it for sake of the sport, who between them catch and
kill a multitude of these voracious enemies of the fish, which, in
the water all the time, manage to destroy untold numbers of fish.

The oft-repeated remark, ‘‘in former years this river used to be
alive with fish,” is very well in its way, and is, moreover, true; but
it must not be forgotten that in former years there were not so many

people requiring them for food.
28 THE GOLDFISH AND ITS CULTURE.

A bit of forest in which grow a few chestnut-trees was, by the
then few village boys said to be ‘full of chestnuts,” but now, when
the village has become a large town or city, the few chestnut-trees
are not looked upon with the same admiration because, though in
equally good condition, they do not furnish chestnuts enough to
go ‘round.

A piece of land of given size supplies in plenty, vegetables for
one family, but if the family increases in numbers, and additions
have to be made to the house at the expense of the piece of
land, it can no longer furnish the original quantity of food. New
land then is added to the field, or, if that is impossible, that remain-
ing is forced to increased production by the use of manures.

Now then, why not apply to pisciculture the rules guiding agri-
culture, when viewed in this light? The fish-consuming family has
inordinately increased, its dwelling is enlarged at the expense of the
fish-producing rivers which are now made to serve other purposes.
New additions are consequently necessary and possible by the
proper use of water-courses that are now going to waste.

Pond-culture is not solely confined to the production of food-fish,
there being many large establishments devoted to the exclusive
culture of ornamental fish.

The largest of these are also in Europe, one in Oldenburgh cov-
ering twelve acres, yielding anually 300,000 goldfish, and affording
employment to many people, A still larger establishment is that in
Austria, belonging to Baron de Washington.

There are besides many smaller establishments scattered about
all over Europe, and generally near the large cities, just as we find
florists in the immediate neighborhood of our own cities.
CHAPTER VI.

THE CONSTRUCTION OF PONDS.

 

The fish-culturist recognizes three kinds of ponds,- which are
designated by the source from which they receive their supply.

First, the creek and river ponds; these are fed from the source
that gives them their names, and which may be, in fact, usually is,
in the immediate neighborhood. The water may be conveyed to -
the ponds either by the action of a pump or by means of a drain,
the latter undoubtedly being the least expensive, and the most relia-
ble, besides requiring no further attention than to turn on or off
when so desired.

Second, spring-ponds, those fed by a spring, and it may be said in
favor of such ponds that the supply of water is steady and of uni-
form quality and temperature, besides being free from mud.

Third sky-ponds, those that receive their supply from the rain that
falls, and which is drained off or runs from the surface of adjoining
fields.

The value of a pond is based upon the reliability of its water
supply, the quality of the same, as also that of the soil that forms
the floor of the pond. Last but not least, is the location of the
pond. The locality ought to be such that without any special
expenditure of time, the pond can always be under supervision, thus

guarding against pilfering upon the part of mischievous boys, the
2)
30 THE GOLDFISH AND ITS CULTURE.

depredations of muskrats, herons, cranes, etc. The water that
supplies the ponds would better come from a spring or be gathered
in the manner described for the sky-pond, as by this way one will
avoid the annoyance and destruction caused by snakes, muskrats,
frogs, etc., that are always found in small rivers and creeks, and
which are sure to find their way to the pond, causing much
trouble, to say nothing of the money value of that which they
destroy. Besides this, the ponds should have some natural protec-
tion against the high winds of spring time. This is very well
afforded by a clump of trees close by, but much better if the pond
is situated in a hollow between two or three small hills, These not
only shelter the ponds, but tend to keep them warm by retaining the
warmth of the sun in the spring, just at a time when it is most
needed. In a warm and protected location of this kind, the fish
will spawn several weeks before the ordinary beginning of the
season, the young, of course, being ready for sale that much sooner,
and the ponds are vacated for a second crop, thus bringing a quicker
and more liberal return on the investment.

Lastly, it is of but little use to locate ponds in a neighborhood
that does not afford a market for the product, unless, indeed, the
amateur should be in correspondence with such parties as would be
likeiy to find it to their interest to handle his stock,

The foregoing remarks on ponds and those which follow are
made with an especial view to the culture of goldfish, so that the
novice as well as the amateur may get a distinct idea of the proper
method of locating and constructing them, for upon this depends
the success of the enterprise, and more so when it is engaged in for
the purpose of yielding an income,

We come now to a consideration of the immediate and practical
points concerning the subject upon which we are engaged and which
we wish to see in running order. After having determined to
THE GOLDFISH AND ITS CULTURE. 31

devote his spare time to the cultivation of goldfish, the amateur will
hardly know where to commence or what to do first, neither will he
know how to do it. That want the author thoroughly appreciates,
and it is his aim to supply it in these pages, at the same time bearing
in mind that the great majority will probably have but a small capital
with which to commence business, and must necessarily confine
themselves to such things as are most needed when making a start.
After a beginning has been successfully accomplished, other and
useful accessories may be added from time to time that will undoubt-
edly greatly reduce labor and enhance the enjoyment of the pursuit,
for if one does not take any interest in what he is engaged he can
not hope to derive from it either pleasure or profit.

The first thing then is to determine on a favorable site for the
location of the ponds, This, as previously stated, should be one
protected from cold winds and fully exposed to the sun, not for-
getting that the soil to form the floor of the ponds should be as rich
as possible. It must also be borne in mind for it is a very essential
requisite, that every pond must be drawn off at times, and independ-
ently of all others. When this can not be accomplished by turning
to account the natural declivity or resources of the site, the series
must be so arranged that this may be accomplished in sections, or, in
other words, the ponds so situated that two or three or more, as the
case may be, can be emptied at will.

The manner in which ponds are to be constructed in any given
case is, as a matter of necessity, to be governed by the circumstances
as they exist, anything favorable for them to be taken advantage of
and turned to good account. A natural valley or hollow may be
dammed up at the lower end, thus enabling the culturist to place his
ponds on top of the ground, so to speak, or they may be made by
digging out the soil to the required size and depth to receive the
frames hereafter to be decribed.
32 THE GOLDFISH AND ITS CULTURE.

As before stated, there are many enemies which prey upon the
goldfish, and all of which are to be guarded against in the construc-
tion of the ponds in which they are expected to live and increase.
If left alone and without the protection of man, the circumstances
must be exceptionally favorable under which they can thrive and
multiply. For the systematic raising of goldfish, therefore, a series
of ponds is indispensable, each of which is constructed and arranged
to meet the requirements of the specific purpose for which it is
intended. All of them, however, are based upon the same funda-
mental principle and must have adjustable inlets and outlets, other-
wise they can not be under complete control, the reason for which
a little experience will soon explain. ‘The number of ponds needed
for the culture of goldfish does not exceed four, and in their order
are the spawning-pond, rearing-pond, storage-pond, and winter-pond.
The spawning-ponds or ‘‘beds” are those ponds in which the parent
fish are placed when the breeding time arives, and are to be kept
there throughout the duration of that season, and solely for the
purpose of depositing the eggs. The 7vearing-ponds are those in
which the young fry is placed or ‘‘ planted” and to keep them until
they are of a marketable size. The storage-ponds are for the purpose
of keeping saleable stock until wanted, and in a situation readily
accessible at a moment’s notice. The last in order is the wénter-pond,
in which the parent fish, and those of the younger that are intended
for the same purpose, are carried through the inclemencies of the
winter.

The greatest depth of all the ponds, the winter-pond excepted,
should not be made to exceed twenty-four (24) inches, and this to be
at that end where the outlet is placed. From twenty-four inches at
one end the depth should gradually decrease until the water depth
at the head is not greater than six (6) inches. (See illustration.)

The upper edges of the dams of the ponds should not be less
THE GOLDFISH AND ITS CULTURE. 33

than six inches above the highest water capacity, thus avoiding over-
flow during heavy rain-storms; neither should they be less than
eighteen (18) in width. It is also necessary that the dams be made
very carefully, so that when soaked with water they will not sink or
cave in with their own weight. A most excellent material of which
to build them consists simply of sod cut into suitable pieces and laid
one upon another, just as a stone-mason lays one stone upon the
other, the whole when thus laid becomes very solid and compact,
and capable of resisting considerable pressure, and will withstand
the wear and tear of the weather and the weight of the body when
walking over them. Where there is danger prevailing from a

sudden freshet in an adjoining creek, it is a wise precaution to build,
in addition, a strong dam on the outside and in the direction from
which the danger is expected. For greater safety this dam may be
in its turn protected with boards, so as to prevent gradual washing
away. Each inlet, 7. ¢., the point at which the water supply makes
its way into the pond, is to be guarded with galvanized iron netting
of atolerably coarse mesh, about eight to the inch, as a small mesh
clogs very readily, and only adds the additional care of keeping it
clean. The outlet is formed of two gutters of which one fits in an
upright position tightly on the end of the other, which leads through
the bottom of the dam, forming a right angle. .(See illustration.)

The one leading through the dam is closed tightly on all four
sides, but on the upright one the side facing the pond is closed
with adjustable sections cut from flooring boards. By means of
34 THE GOLDFISH AND 1TS CULTURE.

these movable parts the level of the water in the pond can be
regulated as occasion may require. The overflow, that is, where
the water is running out, is guarded by a wire screen of the same
sized mesh as before mentioned, and adjustable in the same manner
as the other boards protecting the opening.
When it is desirable to drain the pond, one
section or board is removed at a time, always
taking care to place the wire screen upon
the top by letting it slide down into the

 

grooves, (See illustration.)

OUTLET FoR Ponp. A most important point, and one to be
insisted upon in the construction of ponds, is to so arrange the water
supply that it will at all times be under complete control. Each pond
is to receive its supply independently of all the rest, and the water
must also, when need be, be cut off from the pond without inter-
fering with the supply of others. The supply channel must likewise
have an independent ‘‘run,” so that the water it contains when not
wanted for use in the ponds, may find its way out of the establish-
ment. This point is one of great importance, especially during heavy
rain-storms, as the large increase in the volume of water would cause
the ponds to overflow and probably do great damage.

THE AUTHOR'S ESTABLISHMENT.

 

The accompanying diagram will serve as a reliable guide for the
construction and arrangement of a complete establishment for the
raising of goldfish.

It will be observed that the ponds are arranged in a semi-circle,
not because the ‘‘horseshoe” is all the rage, but simply for the
reason that the little valley in which they are located is encircled by
small but steep hills running in that direction. As previously stated,
the disposition of the ponds must of necessity be in accordance with
the topography or ‘‘lay of the land” in the locality determined upon,
and the amateur will have to follow accordingly, though there are
changes and modifications that he can make, and in many instances

with great advantage.

THE PROPAGATING BED.

 

Having now had a general view of the ponds, the reader’s
attention is directed to a detailed study of them, each one separately,
the method of their construction, and the reason why they differ
from one another; for, being made each with a specific purpose to
serve, they of course must be built with that object in view.

The spawning-pond, or ‘‘propagating bed,” is situated at that
end of the rearing-pond where the water makes its entrance. Itisa
division consisting of a board frame eighteen (18) inches in depth
and four (4) feet wide by eight (8) feet long, fashioned very much
like the frame of a gardener’s hot-bed. This frame, when ready, is
to be sunk about two inches into the soil composing the bottom of the
pond, and very accurately at that; for if this precaution is not taken,
the fish are very apt to escape from the pond through any aperture
that may be left. The upper edge of the frame should be not less
than six inches above the usual level of the water, thus preventing
the danger of overflow. In the side facing the supply drain, about
two inches above the water level, and in the other forming the
division of the rearing-pond, about one inch Jdelow this level, small
openings for the entrance and exit of the water are cut and care
fully covered with galvanized iron-wire gauze, of about eight meshes
to the inch.

a
38 THE GOLDFISH AND ITS CULTURE.

This box, the bottom of which is formed by the floor of the pond,
is to be covered with a well-fitting frame, mounted upon hinges and
also covered with galvanized iron-wire netting of one mesh to the
inch. This wire screen serves to prevent the approach of numerous
enemies that would otherwise greatly interfere with the spawners, if
not destroy them altogether. By following the above given direc-
tions for the construction of the frame the greatest economy possible
can be had, for the lumber in the board as obtained from the dealers,
measures twelve (12) and sixteen (16) feet in length, so that the
measurements, eight by four feet, can always be had without unnec-
essary waste of lumber. Besides this, the wire netting is obtained in
any length, and also four (4) feet in width, so that here too is a
saving of material, and consequently of expense.

Inside of this frame, or box, as it may be called when placed
into position, another frame upon which wire netting is stretched, is
to be sunk. The size of the mesh is to be such as is best adapted to
the size of the fish that are to be placed in the pond. It is very easy
to see that this false bottom subserves a very useful purpose, and
often saves time that at the moment is otherwise valuable. When,
for one reason or another, it is desirable to remove the fish, the only
requirement is simply to raise the frame to get it into shallow
water, when the whole contents of the pond can be examined at
ease.

A spawning-pond, such as the one described, can be, and with
propriety too, constructed separately and wholly isolated. But if it
is made a division of the rearing-pond, a good advantage is secured,
namely, the stream of water that passes through it will carry into the
rearing-pond such of the young fish as were hatched from undiscov-
ered eggs. They will thus escape being devoured by the parent, and
besides will get into the place intended for them, and where the
chances for their growing up are vastly in their favor.
THE GOLDFISH AND ITS CULTURE. 39

THE NURSERY.

This is merely an apartment temporarily established in the
storage-pond, which serves the purpose of protecting the young
during their earliest infancy,

THE REARING POND.

This pond differs from the preceding in several respects. To
begin with, it is five times as large, the size eight (8) feet by twenty
(20) being in many ways the most convenient, as experience has
abundantly proven.

In constructing this, as well as the others, it is not absolutely
necessary that the outlet should be directly opposite the inlet,
though such an arrangement insures the most complete changing of
the contents (the water) by the current passing from one end to the
other. The location of the outlet and inlet must be determined by
the judgment of the builder when seeking to get the best results he
can, from the circumstances and surroundings of the locality in
which he places his ponds. It zs necessary, however, that the inlet |
should be one or two inches above the water level, so that the fish
will be prevented from getting into the supply drain, should there
happen to be a defect in the guard. In constructing the pond, the
remarks applying to ponds in general are to be respected. The
dams must reach six inches above the water level, and the floor be as
uniform as possible, with a regular incline of from six (6) inches
depth at one end to twenty-four (24) inches at the other. The
deepest part to be at the outlet, insuring a perfect and even drawing
off, whenever that may be needed.

One or two plants, such as Nymphaea only, should be planted in
the soil of the bottom, as their floating leaves afford shelter to the
fish in very hot weather. Besides it offers greater convenience for
the fish to reach deep water upon the approach of danger, as in such
40 THE GOLDFISH AND ITS CULTURE.

cases fish always dart to the bottom, and being there, they get out of
the way much ‘sooner. If placed near the outlet, it is also easier to
gather the flowers when the plants are in blossom; this is probably a
small point, but one that will be appreciated upon trial. Should the
plants not be available, one or two pieces of board left floating on
the water will answer the purpose. If it is impossible to isolate the
rearing-ponds from each other, the consequences are not at all
serious, but things should be so arranged that the very large fish are
not mixed up with the small ones, as the latter would then be
deprived of their share of the natural food the pond itself supplies.

THE STORAGE POND.

This pond is for the sole purpose of keeping the saleable fish
where they can easily be secured when desired, assorted according to
variety, color and size, and kept in good condition till wanted.

It is to be so located that it will not interfere with the draining off
of the other ponds.

Its construction does not differ in anywise from that of the
rearing-pond, as indeed it can be used for rearing, if not wanted for
nursery purposes (of which we will treat further on), until wanted
for its destined purpose.

It is best, however, to divide it with boards into different parts of

equal size, so as to secure a general fit of wire covers.

THE WINTER POND.

This is best located close by a spring, so that the constant flowing
in of a stream of water of even temperature will prevent the surface
of the pond from freezing over entirely, in which case the fish would
die. The depth of the pond ought not to be less than three feet,
and its sides closely lined with boards or masonry, thus affording
THE GOLDFISH AND ITS CULTURE. 4i

protection from enemies and preventing caving in. The flow of
water is to enter at one end, traverse the length of the pond, and
leave at the opposite extremity. The dimensions of the winter
quarters need not be very large, as during the winter season, fish in
a natural state, pass that time in a semi-torpid condition, eat no food,
and are not revived until they get the warmth cf the sun in early
spring.

A compartment of four (4) feet by eight (8), and of the above
depth, will carry about fifty fish of eight to ten inches in length
safely through the winter.

Where it can be done, the-fish may be wintcred over in a green
house cistern, or in aquaria where they may be under close observa-
tion, and at the same time be of some ornamental value. If in the
open air, the winter-pond is, of course, to be covered with wire
netting to keep out the various birds and animals that would prey
upon them; it is also well to protect the greater part of the top with
boards, keeping out as much snow as possible.

PART III.

THE PROPAGATION AND CARE OF THE GOLDFISH.
CHAPTER IX.

“Nature my school, the water my field.’””

THE ANATOMY OF THE GOLDFISH.

 

Before we enter into the details of the propagation of the fish,
it is necessary to learn something about its anatomy.

A study of the accompanying cut (which is merely diagramatic)
will greatly assist the reader in getting a clear understanding of the
internal arrangement of the several parts with which it is most

necessary to be familiar.

 

ANATOMICAL SKETCH OF GOLDFISH.

We will consider first the scales, as they are almost the first thing
to strike the eye. These scales are so arranged upon the surface of

the body that they overlap each other just in the manner that a
45
46 THE GOLDFISH AND ITS CULTURE.

carpenter lays shingles on a roof, being disposed in such a way
that the friction incident upon the movement of the fish in the
water is reduced to the smallest proportion. As the fish grows
older and larger the scales increase in size.

Near the middle of the body and running along each side of the
fish, there is a line or row of scales that possess peculiarities distin-
guishing them from other scales.

These scales are pierced with a tubular aperture, and the tubes of
which they are the exit are quite distinct, and form the so-called
‘lateral line.” Through these
tubes a slimy substance or mu.
cous is exuded, which covers the
entire body, seemingly for the
\ purpose of making the fish water-
J proof and of further reducing the
friction in the water. These

 

E tubes always point from the ma-

SCALE FROM LATERAL LINE. (Enlarged.) trix, or root of the scale, towards
the tail of the fish. It is scales of this description that naturalists
refer to when seeking to learn the species to which the fish belongs,
because the peculiarities of their structure differ in them. (See
illustration. )

The next thing most noticeable are the jims, these being named
according to their location upon the body of the fish and subserve
various purposes. The fectoral fins (fig. a.) are those situated in the
place corresponding with the fore-legs of animals, the ventral fins
(fig. b.) being placed where the hind-legs of animals are found.
The dorsal fin (fig. c.) is that one found upon the back of the fish.
That fin situated behind the anus receives its name from that part,
and is known as the anal fin (fig d.), while the tail of a fish is prop-
etly called the caudal fin, (fig. e.)
THE GOLDFISH AND ITS CULTURE. 47

The water in which the fish lives is very nearly as heavy as the
fish itself, the latter then requiring comparatively little strength to
move about. The motion necessitating the greatest expenditure of
power is that of propulsion forward, and is accomplished by the
action of the caudal fin. The pectoral fins are used to change the
water in the neighborhood of the gills, thus serving as adjunct
respiratory organs.

The ventral fins are mainly useful as a brake when the fish wishes
to come to a sudden stop when in motion, or for a backward move-
ment; the dorsal and anal fins serve the purpose of balancing the body.

The gills, which are organs of respiration, are situated on each
side of the head, protected by ‘‘opercles” or gill-covers. (fig. f.)
The gills themselves consist of bony arches which are covered with
a tissue containing a large number of blood-vessels. As a rule there
are four of these arches on each side of the head. The life-giving
principle that supports animal life is a gas called oxygen, and as this
exists in the water, the function of the gills is to extract it. When
the water passes through them, as it does when taken in by the
mouth of the fish, and is pressed through the gills, it comes in con-
tact with the blood-vessels, the oxygen being absorbed into the blood
for the nourishment of that fluid and the body generally.

It will thus be seen that it is not the water that the fish breathes,
as many suppose, but the air contained in it, as can be proved by
placing fish in water from which the air has been taken, by pro-
longed boiling or otherwise.

Fish that are kept in a vessel will come up to the surface where
the air can be mixed with the water when that in the water of the
vessel has become exhausted. It would seem from the fact that as
the fish breathes only the air and not the water, that it could just as
well live in the open air, where it could get plenty. Such is not the
case however, for the gills are so constituted by nature that they
48 THE GOLDFISH AND ITS CULTURE.

need something to keep them apart, so that their surfaces may be
exposed and perform their functions properly, otherwise they would
close together, the blood-vessels would cease to absorb the oxygen,
resulting, of course, in the death of the fish. It is necessary, then,
that a stream of water should constantly flow through them, as it
does, the absorption of oxygen then going on as nature intended.

The feart of the fish lies just behind the head and between the
gills (fig. g.). It is a muscular organ consisting of three parts, an
auricle, a ventricle, and an arterial bulb, The venous or stale blood
is pumped into the gills by the heart, where it receives a fresh supply
of oxygen. From the gills it is sent to an arterial trunk, lying along
the under side of the vertebral column, (fig. h.) from which it is
distributed all over the body of the fish.

As fish have no lungs, they can not possess a voice.

The goldfish is supplied with a divided as7-bladder (fig, i. 1.) which
can be filled or emptied at will. This bladder is a sac formed of a
tough membrane, and is situated between the spinal column and the
stomach, (fig. k.)

It appears that the air-bladder is either for the purpose of increas-
ing the weight of the fish when empty, and decreasing it when full,
thus exercising a modifying influence upon the weight of the fish
when compared with that of the water.

The eves of the goldfish are well developed, but so far as hearing
is concerned, opinions differ, and the question is still disputed. It
may be stated that if fish hear at all, it is with great difficulty.

It is the custom in some places where fish are kept to call them
to their feeding place by the tolling of a bell, and they come, but it
is a question whether they come because they hear the sound, or
that they see the motion of the person ringing the bell, or that of
the bell itself; this, then, can not be cited in proof of the theory
that they hear.
THE GOLDFISH AND ITS CULTURE. 49

Music or the report of firearms does not affect them at all, but
the flash from the discharged gun will scare them.

Do fish sleep? Yes.

In the act of sleeping they do not close the eyelids, for the very
good reason that they have none; neither do they select the night
for the purpose. Goldfish have been seen asleep in the broad sun-
light of the forenoon, and the same varieties have also been found
sleeping at midnight. Their time for resting then, does not occur
at stated periods, but whenever the desire comes upon them. The
fish may very easily be observed in slumber, remaining perfectly
still, the only motion being that of the breathing apparatus and the
pectoral fins, the action being very slow but regular. All the other
fins are at rest, and the pupils of the eyes appear to be drawn back.
The other senses /aste and smell are very well developed.

We come now to the consideration of the process of reproduction.
The organs for this purpose are distributed between two individuals—
the male and the female. The female organs consist of two sacs
located immediately below the spinal column on each side of
the air bladder, uniting towards the posterior end in a single
oviduct which discharges outside, behind the anus (fig1.). These
contain the eggs by thousands and which increase in size when the
spawning season arrives, greatly distending the ovarian sacs. The
ripe egg when it separates from the ovary, passes through a tube
(the oviduct) (fig. m,) the opening of which, as before stated, is
outside, immediately behind the anus. (fig. n.)

In the male fish the spermatic organs which are located the same
as the sacs in the female, secrete a thick white fluid which contains
innumerable small organic bodies, which when discharged and in a
fresh condition, move about, enter the egg, impregnate it and start
the development of the embryo. These bodies which are called
spermatazoa, consist of an anterior thicker part, the so-called head,
50 THE GOLDFISH AND ITS CULTURE.

and the more attenuated part or tail. In the water these little organ-
isms can live but one or two minutes, but when taken from the fish
and placed in a bottle kept at a proper temperature, they may be
preserved alive for six days. This discovery was made by a Russian
fish culturist in 1856 and is very important to the artificial propagation
of fish as it enables the crossing of different species.
The 885 when first spent in the water have the shape of a slightly
pressed in rubber ball, and as soon as they
come in contact with liquid, they expand and
suck it in through a microscopically small
hole. (See illustration.) Zhe spermatic germs
Cc of the male being present in this liquid are thus
introduced and fertilize the egg.

A—Spermatic Corpuscle. B—Germinative Disk.
FERTILIZATION OF FisH Eee. C—WNutritive Yolk.

 

The fecundation of the egg consists in the entry of the spermatic
corpuscles and the subsequent production of a subdivision of the
germinative disc, which phenomenon is called the process of ‘‘seg-

” This is followed by a series of successive

mentation” or ‘‘ furrowing.
changes, of whick the final result is the edéryo, which, subsisting or
being nourished by the yolk, gradually develops into the perfect fish.

The young fish when first hatched is supplied with a sac called
the yolk-bag, from which it derives its nourishment during the early
period of its independent existence. When this has been exhausted
it is then ready to seek other food and this it finds in various
microscopic organisms that exist in profuse abundance in the water.
As the fish grows larger and gains strength, other and coarser food is

sought and devoured.
CHAPTER X.

PROPAGATION.

 

Among fish culturists it is the universal custom to divide fishes
into two classes according to the season in which they spawn; we
thus have summer spawning and winter spawning fish. They are
further more distinguished as they differ in the mode of depositing
the eggs, as some are laid on or in receptacles usually called ‘‘ nests,”
especially prepared by the fish for that purpose, and others again are
dropped loosely into the water without any precautions having been
taken for their protection. In the latter case they again differ in
being either ‘‘adhesive” or ‘‘non-adhesive,”’ in the one instance
adhering to anything they may happen to touch and remaining until
hatched, in the other sinking to the bottom or floating about at
random on the surface.

The goldfish belongs to the summer spawning class, builds no
nest and its eggs are adhesive in the full sense of the word. In those
fish depositing non-adhesive eggs, the extrusion of them by hand,
and their artificial impregnation is profitable, but with the carp-like
fishes, a higher percentage of young is obtained when the spawning
is allowed tc proceed in its natural manner. Besides, their eggs not
being mature all at the same time, would make the operation of
extrusion an oft-to-be repeated affair, and which, furthermore, would
greatly endanger the life of the fish and require much time and

attention.
51
52 THE GOLDFISH AND ITS CULTURE.

Goldfish raising is therefore confined to:—

I. Guiding Nature with regard to the ‘survival of the fittest,’ and with it
of course the pure strain.

II. Assisting Nature by securing suitable spawning resorts.

TIT. Regulating the spawning season, and

IV. Protecting their spawn and young.

SELECTION OF BREEDERS.

As scon as the spring weather sets in with sufficient sunshine to
affect the temperature of the water, the fish in their winter quarters
rise near the surface and become lively again. This is the time to
get the spawning beds ready for action. Whatever month or date
that may be, is determined by the respective locality of the ponds,
viz., their situation in a northern or southern climate, and there,
whether they are exposed or protected. The beds are then filled
with water to the proper level, and all details concerning the pond
are attended to, so that it will be in complete running order. When
all is ready, the fish from which it is intended to breed are selected,
and right here reside the fundamental conditions upon which depend
the production of a good and saleable crop of fish. The fish used to
breed from should be healthy in every respect, of good shape and
color, and of gentle, fully domesticated habits, All these qualities
will be inherited by their young. In regard to the color of the fish,
it is of great importance to know at what age this was acquired, as
such fish that colored at an age of six to eight weeks transmit the
same tendency to their young on an average of 98%. In contrast
with this, those fish whose coloring was delayed until the second
year, when bred, produce but 5% of young that will color in the
first year, while the remainder do not assume their red, yellow, or
white coloring until the second year, a great many never changing,

always remaining ‘‘silver” fish.
THE GOLDFISH AND ITS CULTURE. 53

The coloring attained by the fish generally remains so, though
there are instances in which the red markings may become milky
white, and what was previously white changes to red, or black spots
may appear, or if present, be lost. This may occur either wholly or
in part. A satisfactory reason for this phenomenon can not be
given.

The selection of faultless beauties for breeding purposes, how-
ever, is not absolutely necessary, such specimens are best kept for
exposition purposes. Any fish whose fins may have become injured
in any way, by accident or otherwise, but have grown again in some
crooked or objectionable shape, are nevertheless perfectly fit for the
spawning bed, if they are otherwise in perfect condition, though for
ornamental purpose they would be of little account.

It may be remarked in this connection, and with propriety, that
certain peculiarities in the shape of foreign fish, 7 ¢., those newly
introduced, are in the course of time, lost, when imported into the
United States, the change of climate, locality, food, etc., producing
gradual changes in their typical forms, assuming or acquiring, so to
speak, an Amerrcan type. In view of this, the culturist should
never neglect to infuse new blood into his stock whenever a favor-
able opportunity offers, for by so doing he can keep it up as near to
the original standard as it is possible to do under the change of
circumstances.

At the breeding season the sexual differences are plainly revealed
to the practiced eye of the patient observer—not before. Upon
close inspection the bony plates that cover the gills, the gill-covers,
or opercles, wili be found covered with small white prominences,
usually denominated tubercles. Those fish bearing this distinguishing
mark are male fish. These tubercles appear on the fish when it
is in condition for reproduction, and disappear when that
function ceases to be in an active state, This period may be of longer
54 THE GOLDFISH AND ITS CULTURE.

or shorter duration in different individuals, and it will also be seen
that the number of the tubercles will vary in the different specimens
upon which they are observed. (See illus-
tration.) ‘The usual method of distinguish-
ing the male from the female by not-
Zing the presence of a short dorsal fin
is not reliable; in fact, it is not only
misleading, but false, as such short, or
more properly speaking, ‘‘ deformed”
dorsal fin, is found just as frequently
upon female fishes. The tubercles are

sharp, very similar to the projections upon a

 

rasp, and seem to have for their function
the assisting of the female to pass its eggs through the canal. This
theory is apparently substantiated by the fact that the male uses
them in such a manner by pressing against the belly of the female
that one is irresistibly led to the conclusion that they can exist for
no other purpose.

The females to be selected must show an expanded belly, which
evidences the maturity of the eggs, as it has been stated before, that
when arrived at that period, they increase in size, and it is by this
appearance only that the culturist can decide that the time for the
female to spawn has arrived.

It is worse than useless to place in the spawning bed fish that are
not in perfect condition to perform the functions, as some goldfish
are sterile, and will only disturb the arrangements that have been so
carefully made for that purpose. Whether these particular fish will
remain sterile for a season or for as long as they live can not be
decided, As arule, it is best to select three females and four males
when of good size, or six females and four males, when the former
are small yearlings, for each spawning bed. It is also important to
THE GOLDFISH AND ITS CULTURE. 55)

match the sizes of the fish; should this not be possible, in case the
females are larger than the males, two or three males may be
required to mate with the females. The best age for spawners is that
between two and four years.

The selection having been made, all those fish not wanted for
present use are returned to the winter pond.

 
CuHaptTer XI.

PREPARING THE SPAWNING BED.

 

As the goldfish deposits its spawn upon plants that live in the
water, it is necessary that the natural condition of things be closely
imitated in preparing the bed in which the fish are expected to
spawn. These plants can be obtained from any neighboring creek
or marsh (that with a gravel bottom preferred). Those marsh plants
possessing fibrous roots are either pulled or dug up with their roots
entire; they are then washed thoroughly to cleanse them of the
adhering mud, and clesely examined to see that there are no eggs of
other fish or insect larvee upon them, Having secured enough of
these for the present, say half a dozen good clumps for each bed,
they are then placed loosely in the water of the bed, along that side
where the sun shines upon them in the morning. On these roots the
females will deposit their eggs Later in the season, when aquatic
plants have commenced to grow, these roots can be removed and
replaced with such aquatics as the Horn or Waxworth (Ceratophyllum
demersum), and the Canal Pest (Amacharis canadensis), These plants
are especially good to catch the eggs when dropped by the fish.

The water supply is now shut off from the bed, only an occa-
sional supply being let in to preserve the proper height at which the
water should remain.

If the goldfish are kept in places where it is impossible to get

them out, and their spawn is wanted, large bunches of the fibrous
56
THE GOLDFISH AND ITS CULTURE. 57

roots can be tied to a string fastened to the shore, and allowed to
float about upon the water. When containing spawn, they can be
brought out merely by pulling the string, when the eggs can be
removed and taken care of by the one in charge.

When the fish are wintered over in sheltered localities, as a green-
house for instance, the spawning season will commence a great deal
in advance of that outside. In such a location, spawn may be
expected from the middle of February, while that event seldom takes
place in the open air earlier than the latter part of April or the begin-
ning of May. When the spawning has begun, it is continued until
the setting in of frost, with now and then an interval of a week
or two.

In northern climes, where the season is short, it may be length-
ened by placing over the spawning bed and nursery frames covered
with glass, the principle being the same as that of the gardener’s
hot-bed. If this is done, it must not be forgotten that in fair weather
an abundance of air should be admitted, and also that the bed is to
be protected from great and sudden changes of temperature, as
either would be fatal; in fact, the breeder is to exercise his intelli-
gence in the matter, for he certainly must know that as he is keeping
up a kind of artificial climate, he must not forget to preserve it as
evenly as possible, otherwise one cold night would (if the frame had
not been replaced after airing the bed) destroy many days of patient
toil.

If, in between spawning periods, the fish should rest longer than
is desired by the breeder, the males are to be changed from one bed
into the other, and the water in the latter well aerated by letting a
stream flow through it for a whole day, when the spawning will soon

be in full process again.
CuaPTER XII.

CARE OF THE EGGS.

 

“In the morning sow thy seed,” says SoLomon :—This advice
of the Sage of the East has many applications to the affairs of
every day life, and amongst other things it may well apply to
the subject under consideration, not in its literal sense, but in the
spirit of the admonition. As the early morning is the best time to
sow seed, so is the morning of the season the best time to spawn the
fish, as they are then in their best condition for that process, and
besides the young will have a much better opportunity to grow with-
out molestation, their most inveterate enemies not appearing until
after the season is further advanced. Thus it is that a greater per-
centage survives, which, becoming marketable before the main crop
arrives, bring higher prices and give the culturist encouragement by
a quick return upon his labor and capital.

Again our quotation hits the mark, for the earlier the spawn is
taken from the bed the greater will be the reduction of losses, as by
leaving it exposed, the spawners themselves devour it.

The early morning is the favorite time for the goldfish to spawn,
though it is sometimes kept up until noon. The fish are seen chas-
ing each other and rolling over the material thrown into the water
for that purpose. Upon inspection of the loosely floating clumps of
roots, we discover that they have adhering to them a great many
small round watery-white, creamy or yellow colored balls about the
size of a pinhead; these are the eggs of the goldfish. The bunches
of roots are then carefully removed from the water, and the individ-

_ual rootlets bearing the eggs are either cut off with a knife or pair of
58
THE GOLDFISH AND ITS CULTURE. 59

scissors, or they may be detached with the thumb-nail. Great care
must be taken not to disturb the eggs or injure them in any way
while detaching the rootlets. They are then placed in a one-gallon
candy jar, filled with clear water of the same temperature as that of
the bed. Such a jar is best not over-crowded, about one hundred
eggs being as many as that capacity can safely and conveniently
carry, the object being to give the young fish, when hatched out,
plenty of room, both to move about and obtain sufficient fresh water
for respiration. When the jars have received their quota of eggs,
they are taken into the house or put into some other convenient
place selected for the purpose, but in such a situation that they will
constantly be under close supervision.

It is best to set them near a window, within the reach of the
morning sun, there to remain untouched until the eggs are hatched.

The time required for the hatching varies from two (2) to six (6)
days, it taking place most rapidly in warm weather, The temperature
of the water, most advantageous for the hatching is between 60” F.,
and go° F., more or less is dangerous.

This method of caring for the eggs secures to them a more
effective guard against enemies, as well as muddy water, heavy rains,
and hail storms, all of which would militate against them if hatched
in the open air and in the ponds. The candy-jar system furthermore
recommends itself for the hatching of the eggs in this, that the whole
process is under complete control and offers every facility for close
inspection at all times. The jars can be obtained anywhere, are
cheap, and are very convenient to handle, in short, just the thing for
the purpose. For convenience of study, the marking of dates,
names of varieties, etc., together with any notes that it is desired to
make, a piece of paper can be pasted upon the outside of the jar,
it will always be there, and the record kept upon it can always be
seen at a glance.
CHAPTER XIII.

FIRST CARE OF THE YOUNG.

 

About the second or third day after the young have left the
eggs, they become strong enough to swim freely about in the water,
and can then be transferred to the nursery, temporarily established
in some part of the storage pond, which is generally not in use at
this season. Here they are carefully guarded until they become
about half an inch in length. For this purpose the storage pond is
filled with water to a height of six inches at the deepest part; all
living creatures, especially insects and their larva, are to be removed
with the aid of a fine dip-net. No plants should be placed in the nurs-
ery, as it is important that it always be under the control of the eye.
Each morning the young are carefully inspected, and any enemies
that may happen to have made their appearance must instantly be
removed and killed. During the remainder of the time, a cover is
kept over the frame in order to prevent the dragon-flies from deposit-
ing their eggs in the water, as these, when hatched, are very destruc-
tive to the young fish.

As the different lots of eggs are hatched in the jars, and the
young become strong enough to swim about, they are placed in the
nursery until a division of four by four (4 by 4) feet contains from
four hundred (400) to five hundred (500) fish. The next division
is then prepared and stocked in the manner described, and so on

until all the spawn has been so treated.
Go
THE GOLDFISH AND ITS CULTURE. 61

At the expiration of about a week from the time the first young
were placed in the nursery, the strongest are taken out in the follow-
ing manner: A candy jar is filled half-full of water from the nursery,
and set right in the center of the bed and resting upon the bottom of
it. The largest fish are now slowly and gently caught with a
small dip-net, one at a time, and immediately in the same careful
manner placed in the jar, counting them as they are transferred. It
is not advisable to place more than fifty of these little fish in the jar
while removing them, neither should they remain in it longer than is
necessary to transfer them into the rearing ponds, the whole time
consumed in the operation should not exceed a few minutes.

The morning is the proper time of day to perform this operation,
as the temperature of the water in the various ponds is at that time
most uniform. If the manipulation is done at any other period of
the day, it becomes necessary to gradually equalize the temperature,
as a difference of a few degrees only would prove fatal to the tender
young if suddenly removed from one water to another.

 
CHAPTER XIV.

SETTING OUT THE YOUNG FISH.

 

The day before the fish are transplanted from the nursery into the
rearing pond, the water is let into the latter, but not sooner than this.
The reason for this is, that the water, if allowed to stand longer,
would produce an over abundance of food, and with it, of course, a
host of dangerous insects. If the young fish were put in the pond,
while in this condition, the insects would at once give chase and
devour them.

The little food these tiny fish require, during their first days of
existence, is found in sufficient quantities in the new water. By the
time their enemies make their appearance, especially those of the
insect kind, the fish have grown too strong for them, and are very
well able to look out for themselves.

In transferring the young from the jar, to the rearing pond, it is
much better to sink the jar and allow the fish to make their escape at
will. This precaution enables them to gradually become accustomed
to the change, thus avoiding a shock by the sudden emptying of the
jar.

In this manner the young are ‘‘ planted” in the rearing ponds,
at the rate of 250 to each pond, of 8xzo feet in size. Here they
remain until they have acquired their coloring, and have grown
large enough to be saleable.

This may be variously from six weeks to four months, according

to circumstances, and the care expended upon them.
62
THE GOLDFISH AND ITS CULTURE. 63
FISH CULTURE IN THE PARLOR.

Though the instructions detailed above were given with reference
to cultivation in the open air, yet by following them the same thing
can be done in the parlor, but on a small scale, and with limited
resources. The writer has often delighted his customers by furnish-
ing them with sprigs of water plants, upon which eggs were adherent.
These they hatched in a glass tumbler, placed upon the window sill,
gradually increasing the size of the vessel, and consequently the
quantity of water as the young grew up, until they were finally ready
for permanent residence in the aquarium. Such specimens are
generally looked upon with great pride by their owners because they
are home-bred and grew up in the midst of the household, where all
could watch them and learn a bit of natural history without an effort.
The spawn for this purpose can frequently be obtained from any
well managed aquarium, if the habits of the goldfish are understood.

 
CHAPTER XV.

CARE OF THE PONDS.

 

It being the intention to raise goldfish for aquarium purposes,
this final end must never be lost sight of, for with that end in view
we direct all our efforts to make the net result in every way
satisfactory. To that effect the water in which they are grown
should have no current, neither must there be a continuous supply of
fresh water from the outside. The natural habitation of the goldfish
is standing water, and if they are cultivated in like conditions, they
will the better be fitted for the life of confinement in the aquarium.

It is only necessary to add water to the ponds now and then,
just as the fluctuations of the season may dictate, and only in
quantities sufficient to preserve a uniform height in the ponds.
When additional water is required, it should be turned on from the
supply drain, in the day time only, as one can then watch it better
and keep out any extraneous matter that may happen to be in the
drain.

Under no circumstances should it be allowed to run in during the
night, nor in the absence of a reliable person who could turn it off in
time, in case a storm should come up. Any possible damage to the
ponds can be prevented by keeping out the accumulated water
during a heavy fall of rain.

The supply drain should always be kept free from obstructions of
any kind, and especially when a storm is approaching, it ought to be
examined to see that it will quickly carry off the rainwater without

interruption.
4
THE GOLDFISH AND ITS CULTURE. 65

The grass and weeds that grow along the edges of the dams are to
be kept closely cut, for, if permitted to remain, they not only detract
from the appearance of the establishment, but they afford excellent
shelter for the numerous enemies that constantly threaten the fish.
The ponds themselves require a daily examination, and anything
found in them that is not wanted can be removed. Bits of cut
grassor leaves from neighboring trees do not harm anything particu-
larly, but they are liable to clog the outlet and cause the water
(should a storm of rain arise) to rise to an undue height.

Besides these, there will often be found insects, larve, etc., which
can be removed with a dip net, while other and larger enemies may
appear that will require the services of a trap or the exterminating
influence of fire-arms.

When the fish have been taken out of the ponds in the fall
(which is done by draining off the water, to be described elsewhere),
the soft mud is removed from them witha hoe. This mud, when
frozen thoroughly, will make a first-class compost for flower beds in
the following spring. The wire guards from the inlets and outlets,
together with the adjustable sections from the drain pipe, are taken
into the house for safe keeping during the winter, the ponds being
left in a dry state until again needed the succeeding spring. The
frosts of winter will kill any remaining vermin, purify and fertilize
the soil of the bottom while the absence of water will offer no
inducement to muskrats, whose advent would greatly damage the
dams.

Any projected changes, alterations, improvements, or the con-
struction of new ponds should be completed in the fall, so that
everything will be in readiness for the spring; then a late season that
crowds spring-work in the fields and garden will be of little conse-
quence, as the culturist is prepared to take advantage of the first

coming of warmer weather.
CuapTer XVI.

FISHING THE PONDS.

 

For the purpose of taking the fish from the ponds, the water in
the latter is drained off. But before this is done two or more large-
sized clean tin vessels are to be provided—tin buckets or wash-boilers
will answer very well. Also two dip-nets must be obtained, the one
with a handle about seven feet in length, the other a smaller hand-
net. The storage ponds are then prepared for their final purpose,
and when this is all correctly done, the movable sections at the out-
let of the pond containing the fish are removed one at a time.
When the water is sufficiently low, the fish are carefully taken out
and at once put into the tin vessels, which have previously been
partly filled with clear water, assorting the fish according to size,
color, etc., at the same time. When this is completed, the fish are
put into their respective quarters in the storage pond with as little
delay as possible. It is also at this time that the breeder makes his
selection of those fish he wishes to breed from; these ought at once
to be put into the winter pond.

During this fishing process it is impossible to avoid making the
water muddy; so, to prevent the weakening of the fish, the supply
drain is opened, allowing a constant stream of fresh water to flow

through the pond.
66
THE GOLDFISH AND ITS CULTURE. 67

Again the writer admonishes caution; do the work gently and
neatly, as every broken fin or lost scale reduces the value of the
fish so injured,

DOMESTICATING THE FISH.

When in their respective ponds, it is not necessary to feed the
goldfish, as nature provides them with all the food required for their
proper growth and nourishment; but when removed to the storage
ponds, additional food in small quantities may be given to them.
This may consist of stale (but not moldy) white bread, dried in an
oven or the open air, and crushed to resemble fine hominy or corn
meal. Either of these, or both, in small quantities is strewn on the
water; the fish being unaccustomed to it will eat but little at first,
neither will they snap at it immediately. Gradually, however, they
take kindly to it, and the quantity may be increased, keeping pace
with the appetite they evince for it, giving it to them at a regular
hour each day.

This feeding is not intended for the purpose of making them
grow, but rather to prepare them for the change of diet that will
ensue when transferred to their future homes.

When the fish take such food and thrive upon it, they may be
considered domesticated, and can be disposed of as pets, they then
being in condition to take readily to the more confined life in an
aquarium.

When performing work of any kind on or near the ponds,
or other receptacle where fish are kept, or in feeding or hand-
ling them, a patient and gentle manner is advisable, as it tends to
tame the fish by giving them confidence. On the other hand, if
they are frequently scared, they become of a wild, restless nature,
and will dart away on the slightest provocation,
CuHapTer XVII.

CARE OF FISH IN STORES.

 

When fish are kept in tanks as merchandise by dealers, the loca-
tion of such reteptacle should be well lighted, airy, and not per-
mitted to freeze. As was stated in another chapter, it is the oxygen
contained in the water that the fish breathes, and it is therefore nec-
essary to consider what means can be employed to keep up a contin-
uous supply of it. One way, the most in use, although the worst for
the retail customers, is to keep a stream of water constantly flowing
through the tank. Now, thisiswrong. Goldfish are intended to live
in standing water, and should not be made accustomed to the con-
trary, as the reversing again of the character of the water often
proves fatal to them.

The proper way to keep fish is in pure standing water, to which
the necessary oxygen is supplied by the action of aquatic plants,
these every dealer in fancy fish is compelled to keep on hand, if he
understands the principles upon which the aquarium is managed, and
if he wants to make the handling of fish a financial success.

Aquatic plants, when in a healthy condition, exposed to the light,
consume the carbon in the carbonic acid gas which is produced by
the fish as refuse matter, and give off the oxygen, which in turn is
appropriated by the fish. This answers the question as to how many
fish can be kept in a certain tank, for it is easy to understand that a
locality favorable for the growth of plants will produce the greatest
amount of oxygen in the water. Large fish consume more oxygen
than small ones, so the proportion of fish to the tank must nat be

greater than the supply of oxygen the tank can produce. Besides all
68
THE GOLDFISH AND ITS CULTURE. 69

this, a light location is more beneficial to the color of the fish, and
also affords a better control of the contents. Such a store-tank may
consist of a large aquarium with glass sides, or it may be a wooden
trough thirty (30) inches in width, ten (10) or twelve (12) inches in
depth, and of any convenient length. The frame to form the sides
and ends is made of one and one-half (134) inch stuff, the bottom
being formed of flooring boards, as they are fitted with tongue and
groove. To make a tight job, pieces of flag leaves, such as are used
by coopers, are laid upon the edge of the frame, and the strips of
flooring board nailed down securely, one at a time. The groove
in each piece is thickly painted with pure white lead ground in oil,
the tongue of the next then being tightly fitted into it, and so on,
piece after piece, until the bottom has been completed. The best
way, probably, is to nail the flooring crosswise upon the frame, as
that makes the trough very strong and capable of carrying a con-
siderable weight of water, the smooth side of the boards is of course
turned towards the inside of the tank.

Such a tank, however, when in operation should not contain a
greater depth than six (6) inches of water, rather less probably, both
for the convenience of catching the fish and the better admission of
light. The trough must be kept clean, every now and then removing
all the contents and thoroughly sponging the interior.

This may appear to contradict the author’s method of managing
an aquarium ; it may be said in explanation that dealers’ tanks are, as
arule, overstocked, and therefore require a somewhat different treat-
ment; they are, in comparison with a regular aquarium, the same as
a hotel is, compared with a private residence.

While in the hands of the dealer the fish should receive a limited
but regular supply of food, and should disease make its appearance,
the sick fish are at once taken out and put by themselves.
CuHaPTeR XVIII.

THE CARE OF GOLDFISH IN AQUARIA.

 

An aquarium may be made of any water-tight vessel, the material
of which will not alter the qualities of the water by impregnating it
with anything that would stain it or give it an offensive odor, either
of which would be detrimental to the health of the fish.

The shape of such a vessel is usually determined by the require-
ments of the duty it is expected to perform, and should not, therefore,
be wider at the top than at the bottom, for then the fish would leap
out; neither should it be too narrow at the upper part, for this would
exclude the atmospheric air by a reduction of the water surface.
The old-fashioned fish-globes are about the worst vessel that can be
selected for the keeping of goldfish as pets; they will do well enough
for a temporary display of the fish, but for permanent use they may
be compared with the Black-hole of Calcutta. Besides they are
extremely dangerous, in regard to their round shape, as there are
several cases on record where fish-globes, hung near a window, set
fire to the lace curtains or the carpet, the globe acting like a con-
densing lens.

When the vessel in which to keep the pets has been selected, it
is thoroughly cleansed with water only, the bottom is then covered
with well-washed river, or white sea-sand, to a depth sufficient to
allow the planting of one or more varieties of aquatic plants. The

number of these from which to make a choice selection is large, but
70
THE GOLDFISH AND ITS CULTURE. 7k
in these pages only the leading and more desirable ones need be
mentioned, the list being arranged according to their relative value
as oxygenators. For use during the winter season, we select all or

part of the following varieties :

Myriophyilum spicatum. Vv Sagittaria natans.
Ludwigia Mulerttii. Ceratopnyllum rosa.
Cabomba Caroliniana. Fontinalis antipyretica.

Either one of these, grown as a single specimen, if of sufficient
size, will do the work of aerating the water during the colder season.

   

AQUARIUM.
If the tank is of a sufficiently large size, specimens of all of them may

be introduced, and as all bear differently shaped and colored foliage,
they will greatly enhance the attractive appearance of the aquarium.

For the summer season we may make our choice from the following:

Ceratophyllum demersum. Ludwigia Mulerttii.
Anacharis canadensis. Vallesneria spiralis,

’ Sagittaria natans, Potamogeton crispus.
Potamogeton pussilus. Cabomba roszfolia.

In both seasons we can add to the aquatics named, various kinds
of marsh plants and those aquatics that float upon the surface, all of
which add to the ornamental beauty of the collection. It may be
mentioned that the plants put in a vessel containing fish are not

placed there for the fish to eat, as many suppose. Some fish, how-
72 THE GOLDFISH AND ITS CULTURE.

ever, have the habit of biting and tearing the plants from a spirit of
mischief, very much like the restless horse that gnaws its crib.

This destruction of the plants can be obviated by placing in the
aquarium such varieties as the fish objects to, for it is a fact that they
manifest a liking for one kind and a repugnance to another.

The roots of the plants are imbedded in the sand, and bits of
rock or pebbles placed around them to retain the plant in place, so
that it will not be shifted about in the water. The vessel is then
filled with ‘“‘pure drinking water” to within a couple of inches of
the top (See illustration); the water, if not fit to drink, can not be
fit to be put in the aquarium, so that it is very essential that it be of
prime quality.

When the water is in, one or two frog-tadpoles and a couple or
more of pond snails are put in for the purpose of consuming any
decaying vegetable matter that may appear, and to keep down as
much as possible the growth of conferve; the number of tad-
poles and snails must be determined by the size of the vessel and
the rapidity of growth of the alge, etc.

When all these preparations have been made, add a pinch of

table salt, and the aquarium is ready to receive the fish.
Before they are put into it, however, the temperature of the

water in the vessel in which the fish are brought must be equal with
that in the aquarium. This is easily accomplished, and does not
subject the fish to any risks that would either make them sick or be
fatal to their lives.

When the temperature has been equalized, the fish are gently
introduced to their future home, taking care that they are not
plunged in so roughly that they become frightened. This perform-
ance may, under some circumstances, consume an hour’s time,
when, for instance, the fish have been carried a distance during
severely cold weather, as then the changing of them from the
THE GOLDFISH AND ITS CULTURE. 73

transporting vessel into the aquarium must be made with great
care.

The shape of the aquarium and the location in which it is placed
determine the number of fish that can comfortably live in it. Should
the location be bad as regards light, the amount of oxygen generated
in the tank will be less, while if the situation is highly favorable in
‘every respect, the evolution of the life-giving gas will reach its max-
imum degree.

The quantity of water required for a given number of fish is
regulated by their size and the nature of the treatment they have
received before they came into our possession. If, for instance, they
were raised or had been kept in running water, or were newly caught
in a large pond, they will naturally require a much larger quantity of
water than if they had already been accustomed to a life of captivity.

As a rule, and it is a reliable one, each fish of three or four
inches in length should be supplied with a gallon of water in which
to live. Of course this norm may be disregarded for a limited
period with impunity, but for the continuous wellfare of the fish it
must have its proper share of water.

The location of the aquarium should be such that the plants in it
will be stimulated to their full capacity of growth, as this is the prime
factor upon which depends the maintenance of the aquarium in a
proper condition.

The subject of food is one that is but little understood by the
majority of people, and is also a matter of no little importance.
Most persons, in their anxiety to supply their pets, greatly overdo the
thing; the waste material accumulating in the water, remains until it
putrefies, thus polluting the water and rendering it detrimental to the
health of the fish.

The feeding time should be but once a day, and that at a regular
hour, the food to consist of flies or prepared fish-food, such as is
74 THE GOLDFISH AND ITS CULTURE.

obtained from the dealers. The quantity administered ought not to
exceed what they will immediately consume. Once a week they may
be given finely chopped fishing-worms, or raw beef scraped from the
piece, but only in such quantities as to allow each fish a small mouthful.
If any remnants of the last meal are found in the water, they should be
removed at once, and the feeding entirely suspended for one or two
days following. In cold weather the goldfish has but little or no
appetite, while on the other hand, they eat voraciously in the sum-
mer. The best ten:perature for the water is somewhere between
60° F. and go° F., though the fish can stand it as low as 32” F. and
as high as 110° F. without injury, if the change is not suddenly
made, and a corresponding supply of oxygen present. Cold water
retains the most oxygen, and also has the power of absorbing more
of it from the atmosphere than warm water does. The warm water,
however, is most favorable to the growth of plants, so that the
quantity they furnish fully makes up the difference. It is poor
philosophy to put ice into the aquarium to reduce its temperature,
and it is equally foolish to wrap an aquarium in a bag and allow ice-
water to drip upon it, as this is hardly the thing to do if the person
cares anything for the parlor carpet.

When the fish come to the surface of the water to breathe, it is a
sure indication that the oxygen has become exhausted. A fresh
supply is easily introduced by simply stirring the water with the hand
or dipping it up with a cup and pouring it back again, it is much
better to do this than to put in a lump of ice.

The frequency with which an aquarium is to be cleansed depends
altogether upon circumstances and the individual taste of the owner.
An aquarium kept in the parlor of a suburban residence, and ina
locality surrounded by flourishing shrubbery, needs re-arranging
twice a year only, viz: in the spring and fall. On the other hand,
an aquarium located in a smoky city and kept in a close, badly
THE GOLDFISH AND ITS CULTURE. 75

ventilated apartment, must be emptied frequently and a new supply
of fresh water put into it.

Some people object very strenuously to the formation of alge
upon the glass sides, and on that account clean the vessel very
deligently, removing every particle they can find. Others again
change the water because it does zot form, their taste preferring the
fish in all the natural surroundings of a rural locality.

The former carefully wipes each pebble till it shines, and would
polish the fish too if it were possible, while the latter will walk for
miles to some creek in order to procure some moss-covered rocks,
so divergent are tastes in this matter.

One must be able to exercise his own judgment as to the best
time and when, for the changing of the water in the aquarium,
as it may sometimes be better to leave it undisturbed for some
length of time, and at others to change it several times.

The best means to clean the glass sides from the adhering alge,
when an aquarium is emptied, is by the use of ordinary cooking
salt applied with wet fingers, this will remove every speck with-
out scratching the glass.

The best side of a room for the aquarium is that having a window,
near which it is to be placed, as the light can be increased or
reduced by opening and closing the shutters.

In the winter this position is the best, for the constant ventilation
that goes on in the immediate vicinity of the window protects the
water from the injurious effects of coal and tobacco smoke, and the
poisonous fumes from the gas-burner; in the summer, in close hot
weather, before a thunder storm, it can be easily and effectually
aerated.

There remains yet one point: ‘‘Should the sun shine upon the
aquarium?” This too is a matter of taste, though we would
recommend a middle course, that is, let the fish have the sun part of
The best location for an aquarium is near a window with a

If the goldfish are kept in water that contains no aquatic
ants, it will have to be changed frequently as the oxygen in it

.$ it is consumed by the fish,

 
CHAPTER XIX.

TRANSPORTATION OF FISH.

 

The vessel best adapted for the shipment of live fish, to any
reasonable distance in this country, is a tin can, clad with wood.

The shipping can should be perfectly smooth upon the inside, so
that the fish will be subjected to the least percentage of injury while
en route, At the upper end the can should taper off, forming a kind
of neck or shoulder, similar to that seen
upon the common coal-oil can. This makes
it easy for the contents to slide out when
the vessel is to be emptied. The opening at
the top is five (5) inches in diameter, and
closed with a perforated lid that is fitted in
like the top toa milk can. The perforations | H. MULERTT
consist of half a dozen one-half (14) inch
holes, punched through from the under side

FROM

of the lid, thus leaving the sharp rim of the
holes on the outside where they can do no

 

injury to the fish within the vessel. (See
illustration. ) SHIPPING CAN.
Those cans very extensively used in the coal oil trade, and usually
designated ‘‘ wooden jacket cans,” are about the very best thing
that could be invented for our purpose.
As the Express Companies demand that tin vessels be protected in
some manner or other with wood, we find in these vessels the

17
78 THE GOLDFISH AND 1TS CULTURE.

fulfillment of all requirements of that nature, and at a slight increase
in weight. Besides, these cans are readily obtained in the large
cities, (and smaller ones, too, in all probability), the only necessity
being the enlargement of the opening to make it a complete shipping
can for fish.

When it is desirable to make a shipment of live fish, it 1s
necessary to take into consideration their size, the length of time
they will be upon the road, and the season of the year in which they
are transported, all with reference to the all-important supply of
oxygen, without which, of course, the fish cannot live.

The shipping can is filled with pure water, to four-fifths (4-5) of
its capaciiy only, thus providing ample space for the water to splash
about during the journey, as it is by this constant motion of the
water in the vessel that it is aerated and made capable of supplying
the fish with oxygen.

The hour of shipping ought, if possible, to be so arranged that
the journey on the road may be made at night, as it is cooler in the
summer, does not expose the fish to the great heat of sunlight and
the arrival is made usually sometime in the morning or forenoon
when those at the destination are on hand to receive them. The
cans must be plainly labeled, stating the nature of their contents, so
that they may receive more care in the handling from the express
agents, consequently running less risk of damage. It is also
advisable to notify the party to whom the fish are sent that the
shipment has been made, in order that he may take them from the
agent as soon as possible, otherwise, if they are left to remain quiet
at the express office or freight depot, the fish will be in great danger
of their lives from want of proper care.

If the shipping can is an ordinary small tin bucket, such as are
on sale at the tinsmith’s, the ventilating holes would better be
punched in the center of the lid, the remainder being left unmolested,
THE GOLDFISH AND ITS CULTURE. 79

forming a shoulder against which the water can splash without being
spilled. In all cases the lid must be securely fastened with strong
twine or wire, so that a jar will not displace it.

The above directions apply more especially to shipments that do
not occupy any great length of time in the transit.

If the fish are to be sent great distances over our own country or
exported to foreign parts, the safest plan is to put them in a vessel
fitted up like a regular aquarium. Japanese goldfish have been sent
to Europe with perfect success in the following manner:

A one-gallon candy-jar, (such as are used for hatching spawn) is
fitted up in proper style, with sand, water-plants, snails and tadpoles,
and filled nearly to the top with pure water. In this may be placed
four two inch fish, the top then covered with a perforated tin lid,
and the whole set aside for observation for about a week. Dur.
ing this time a tin bucket is obtained of such a size that the entire
candy-jar aquarium will nicely fit into it, the top of the jar being
neither higher nor lower than the upper edge of the bucket. This
tin bucket, or sheath, if you will, serves as a perfect guard against
breakage, and should any accident occur to the jar, the bucket is on
hand to act as a substitute. Furthermore the tin is provided with a
convenient handle to carry it by, and for greater security the jar can
be retained in its place with a heavy wire bar across the top, so
adjusted that it can be removed at will.

On board the ocean steamer, the buckets are suspended by the
handles, the water is not changed, neither are the fish fed anything.

As will be seen, the uncovered shoulder of the jar will admit
plenty of light, so that the plants can act on the water and keep it
fresh, neither can the water in the jar be lost by splashing out, as
when this does happen, it merely falls into the bucket, from whence
it can be returned; the perforated lid admits the air, but at the same

time prevents the accidental escape of the fish.
80 THE GOLDFISH AND ITS CULTURE.

This description of a trans-Atlantic shipping can is not at all
expensive, and is further recommended by its reliability. Make ita
rule, however, to ship only such fish as are in perfect health and
fully domesticated.

While on the road the water in the can should be changed only
in exceptional cases, and then with great care, If the fish become
weak it is a sign that they are not in good condition, and that a
mistake has been made in preparing them for travel, and the simple
changing of the water then will not prevent their dying. The rule
is, do not crowd the shipping cans.

When, upon the arrival of a lot of fish, there happen to be any
dead ones in the vessel, and the balance weak or in a dying con-
dition, or look slimy and pale, with bloody streaks on the fins or
around the scales, it is a sure sign that suffocation has been the cause
of the death of some, and will speedily cause that of the others.
The living ones should at once be placed in a large vessel in the
open air, filled with fresh water, to which a good handful of common
table-salt is added. A clean wash-tub answers the purpose nicely,
and besides, has the merit of usually being close at hand.

This treatment, if resorted to immediately, will, in most cases,

restore the fish to good health.

ENEMIES AND DISEASES OF THE GOLDFISH.
REQUISITES, TOOLS, ETC.
CHAPTER XX.

‘Knowledge is power.”

THE ENEMIES OF THE GOLDFISH

It has been stated elsewhere in these pages that the raising of
goldfish consists largely in the protection of them against their
enemies, and to make the defense most effective it is essential that
we know something about the transgressors, for by being acquainted
with them and their habits, we can more intelligently combat them.
For this end the author has described them in the following lines,
adding to those that are less familiar to the general reader, an outline
of their natural history and viewing them in the successive stages,
during which they endanger the life of the fish. :

Before beginning the description of insects, however, it is proper
to say that the spawn of the goldfish immediately after its deposition,
is sought for by other fish and devoured, the spawners themselves
also engaging in this nefarious practice. Those eggs that have
escaped the notice of the fish are consumed by various smaller
enemies, foremost among which is

THE COMMON POND SNAIL,
(Lymnea fragilis. )
which devours them.
THE WATER ASELL.
(Asellus aquaticus.)
This little creature, of which the accompanying illustration gives a

good idea, is a crustacean, not more than one-half of an inch

in length. It crawls about upon the bottom of the ponds and over
the water plants, searching for food, part of which consists of fish
eggs, to which they are very destructive, devouring them wherever
found.

Another voracious enemy of the crustacean tribe is

THE WATER FLEA
(Gamarus pulex.)

or Flea Crab, Buck Crab, etc. This lively little creature is closely
related to the shrimp found in the ocean. It furrows through the

water in any direction lying on its side, because its back is naturally
bent. (See illustration.) In all stages of its growth it feeds upon
the fish eggs, but in turn, furnishes an excellent food for young fish.

THE BOAT FLY
(Notonecta glauca, )

or ‘‘ Shoemaker, ”

as it is commonly called, is a most voracious
insect. The body is long, contracted posteriorly, convex abcve
and flat below, having hair at the sides and extremities, which,
when spread out, supports the insect upon the water. The
head is large and presents a large eye upon. each side, giving
the possessor the power of vision in all directions. The color

of the body is a greenish grey, the wings are white, of the legs,
THE GOLDFISH AND ITS CULTURE. 85

the four nearest the head are short, but the third pair are very
long, different in shape from the others, very much resembling
boat oars. When in the water, the insect swims upon its
back, using the hind legs as oars for propulsion, while the front ones
are instrumental in seizing its prey. Young fish, tad-poles, and
also insects, ail contribute to supply it with food, to the former,
especially, itisa very dangerous enemy. The instrument or weapon
with which the insect makes the attack upon the victim is a strong,
conical beak.

It is believed that when making the attack, the boat-fly injects
poison into the wound it makes, as seems to be proven by the fact

 

THE Boat FLy. Larva OF DRAGON FLy.

that when once attacked, though subsequently escaping, the victim
always dies in a short time. When upon land, this fly crawls along,
in an upright position, dragging its oars behind it. In the evening,
and at night, it likes to leave the water and make excursions to
other ponds or creeks; from this habit the culturist may take
warning. Its eggs are deposited against the stems of aquatic plants
in the early spring, and again in mid-summer, so that one season
produces two crops of them.

The young make their appearance soon after, immediately
following the example of the parents by swimming upon the back
and eating almost anything they happen to meet. The accompany-
86 THE GOLDFISH AND ITS CULTURE.

ing illustration shows the insect as seen from below when in the
water.

There are two or more varieties of this fly that differ in coloring,
and of smaller size than the one described, though all are extremely
destructive to the young fish —the one just delineated, more
especially.

THE YELLOW-BANDED WATER BEETLE.
(Dytiscus marginalis.)
This rather pretty beetle, lives entirely below the surface of the
water, never leaving it, except during the night when the air is

damp or in rainy weather, and then for the purpose of making
excursions to other localities. The body is of a greenish black
color, encircled with a brownish yellow band—this feature giving
itits name, When taken from the water it exudes a milky fluid of
a most offensive and disgusting odor. The hind legs are shaped
very much like those of the boat-fly, and serve the same purpose.
This beetle is very courageous, attacking fish of any size, as large
ones have been caught, into whose flesh the beetle had eaten large
holes, the beetle itself found in the hole hard at work eating up the
fish. The larva, which is produced twice within the same season,
lives and grows upon tadpoles and young fish.
THE GOLDFISH AND ITS CULTURE. 87

When of sufficient size, and the proper time has arrived, it
changes into a pupa, which in turn, becomes the perfect beetle. (See
illustration.)

THE BLACK WATER BEETLE.
(Hydrophyllus piceus. )

As the name indicates, this beetle is black, shining with a rich,
purple lustre. (See illustration.) It is of larger size than the preced-
ing, and strong in proportion.

 

THE BLack WATER BEETLE.

The beetle itself is a vegetarian, and as such, is not directly
dangerous to the fish, its larva, however, is voracious without limit,
destroying all that comes in its way.

The female of this species spins a white cocoon around the
posterior portion of its body, with the aid of its hind legs, the cocoon,
when completed, being the size of a hazel nut. In this it deposits
its eggs, and after closing it carefully, fastens it to a floating leaf,
adding to it a little projecting point on the top, which by the
way resembles a small mast, retires to the water underneath and
mounts guard. After a few days the young grubs make their
appearance, at first resembling little whitish worms, but possessing
six legs near the yellow head.

It is by the motion of these legs that the grub is propelled through

rest on a water-plant, the head with its fearful apparatus, formed of
a strong pincher with two pairs of adjuncts, which can be moved in
any direction, is placed in such a deceiving position as to almost
always lure an unsuspecting little fish, tad-pole or insect, within its
reach,

As the grub gets larger, it turns darker in color, until having attained
a size of about four inches in length, it has become nearly black
on the back; the under part is then of acreamy white, and the sides
have been fringed with hair. In this state its appearance is extremely
repulsive, being about as ugly as anything can be imagined. The
earliest and best time to destroy them is when the cocoon has been
finished, and the female is standing guard in the water beneath, both
can then be captured and obliterated, in this way great damage is
prevented before there has been an opportunity for development;
very much on the principle of the old proverb: ‘A stitch in time
saves nine.”

The grubs breathe through the posterior part of the body, and
have to come to the surface occasionally for that purpose, at which
time they are easily caught with a dip-net.

In general appearance, the color excepted, the grub of the black
water-beetle resembles that of the preceding.

The beetle, moreover, is very prolific, spinning several cocoons
at two different periods, namely, in the spring and high summer.

Other varieties of this insect exist, the one under discussion being
the most dangerous to the fish. So far as the others are c¢rcerned,
it is sufficient to remember the injunction, allow noth: 1g alive to
remain in the company of the fish when newly hatched.

THE DRAGON FLIES.

The dragon flies (commonly known as snake-feeders) may be
divided into three classes, all very destructive enemies of the fish.

x. The Zibellula possesses a short, flat body, about two inches
in length. (See illustration).

2. The Aeshma is longer than the above, its slender, round
body sometimes measuring six inches in length.

3. The Agrion is not large, the body small and-slender, varying
in length from 14% to 214 inches.

The wings of the first two named, are, when the insect is at rest,
always expanded horizontally, while those of the latter are folded
together, pointing backward.

THE DRAGON FLy.

The hind part of the body in all of them is long, slender, and
composed of ten rings, On the forepart of the body, they have
three pairs of legs, and two pairs of transparent, webbed wings, the
latter in some species glitter like gold, in others they are dotted with
spots of different color; in the Agrion species they are of the same
color as the body. The coloring of the bodies of all, especially the
zshma, is very brilliant, being of a bright green, blue or scarlet,
and sometimes mottled and spotted with various colors,

The eyes are large and prominent, giving the insects a very large

field of vision.
go THE GOLDFISH AND ITS CULTURE.

They all fiy very rapidly, feed upon insects of every description
that they catch flying about, and from this fact they may be made
useful to destroy the mosquitoes in bedrooms and elsewhere. Al-
though very voracious, they are perfectly harmless to man—they
can not injure him in any way. The manner of their copulation is
somewhat curious. The male fastens the extreme back part of its
body to the neck of the female, and thus attached, both fly about for
one or two hours, when, over some water, they separate. The
female then deposits her small white eggs by immersing the posterior
part of the body in the water, attaching them to the submerged
surfaces of water-plants; there they remain until hatched.

The larvee or grubs of the dragon-flies live in the water; those
of the libellula are short and thick, while those of the other genera
are more slender, corresponding with the shape of the adult. The
color of these grubs varies from blackish-brown to a brilliant green.
They breathe through the posterior part of the body, which apparatus
is also used to propel them forwards through the water, making them

good swimmers.

They are extremely destructive to young fish and fish-eggs, upon
which, together with tadpoles and snails, they manage to make a
good living. Instead of hunting their victims, they lay concealed in
the mud with the eyes only protruding from the surface. Whenever
a victim comes within reach, they produce their concealed pincers
by a rapid motion, rarely missing the mark they aim at. (See
illustration. )

There are instances on record where one of the larve of the
libellulae, which was overlooked in the fish-tank, destroyed two
thousand (2,000) young fish in a week’s time.

After they have attained their full growth, the grubs leave the
water, climb upon some object projecting from it, when the _perfect

fly makes its appearance through the back of the grub, rising upon
its wings into the air as soon as they are unfolded and dry.

The eggs are also produced twice in a season, the grubs from the
last deposit, living in the mud during the winter, and produce in the
early spring the first dragon flies of the season.

Their natural enemies are the frog and the water-spider. The
latter, small as it is, compared with their own size, is, nevertheless a
powerful antagonist, attacking them when in the act of depositing
their eggs. The attack is made upon the eye, the largest dragon-fly
thus being easily overpowered by its small but intelligent enemy.

How strange it is that just those animals with which man has the
least sympathy are among his best friends! Such are the toad and
the spider!

 
CuHapTterR XXI.

THE CRAY OR CRAW-FISH

(Astacus fluviatilis)

Is also known as the fresh-water lobster, and should be killed
whenever and wherever met, as it is very destructive to the eggs of
fishes.

It will also occasionally catch a young fish, and often injure
others by snapping at them, tearing away parts of the fins and flesh,
thus rendering a beautiful and valuable fish wholly valueless as
merchandise.

The main damage done by the craw-fish, however, is the under-
mining of the dams, which is not only annoying and costs much time
and labor for repairs, but makes it possible for the fish in the several
ponds to get mixed by passing from one to the other.

THE WATER-FROGS
(Rane var.)

As the heading indicates, there is a recognized distinction between
frogs, there being water-frogs, tree and grass frogs, the latter in no
ways molesting the fish in the ponds, in reality on the contrary,
making themselves very useful to the culturist by destroying harm-
ful insects. The common frog is the one we have to guard against,
both itself and all its varieties, whose destructive habits far outweigh
the little benefit derived from them. Just as soon as they have
completed their gradual metamorphosis, and become perfect frogs,
they prey upon anything that has life, including young ducks, turtles,
snakes and cray-fish, as well as fish. Besides this, the adult deposits

92
THE GOLDFISH AND ITS CULTURE. 93

its spawn in the ponds, and when the tad-poles are hatched, they
consume a great per centage of the natural food found in the pond,
thus depriving the young fish of proper nourishment, in this way
being indirectly injurious.

The frogs are furthermore dangerous, through their habit of
wandering in the night from one locality to another, during their
spawning season, and thus often unconsciously introduce into the
ponds, the spawn of minnows, which being adhesive, sticks to the
skin of the frog, and is, of course, carried about by it.

The frogs make their appearance early in the spring, and it is at
that time that they can be most effectually destroyed in the following
manner: water is let into one of the ponds, to the height of several
inches, in this pond they will collect at night, in order to deposit
their spawn. Next morning, most of the frogs themselves can be
caught with a dip-net, and the spawn also removed and exposed to
the sun to dry up, by merely placing it upon the ground, where the
sun canreach it. If this process is systematically carried out, during
their spawning season, not many frogs will trouble the establishment
during the season. When it appears that all are captured, the pond
is drained off, so that any tad-poles that might have been hatched in
it will die by being dried up in the sun.

In destroying the frogs the culturist must be careful not to
mistake the common American toad (Buffo americanus) for the frog,
as this innocent creature is worthy of our protection. They may
very easily be distinguished by their color, which is brownish and
yellow, the skin moreover being warty. Their eggs also differ from
those of the frog by the manner in which they are joined together;
those of the frog are found in one compact mass, a lump, in other
words; those of the toad, in strings; the eggs of tree and grass frogs
in sheets. If the amateur will bear these distinctions in mind he will
have no trouble ridding himself of a pest and preserving a friend.
94 THE GOLDFISH AND ITS CULTURE.

It will pay to remove the toad-spawn carefully, and put it into a
pond where it can hatch unmolested, which is completed in June or
July. .

Toads in the neighborhood of ponds and gardens are a blessing,
and should not, therefore, needlessly be exterminated.

One of the natural enemies of the frog is the water-spider, which
attacks the young in the eye and kills it. Although the water-spider
has been repeatedly mentioned as a friend, it is not out of place to
keep an eye on him, as he also frequently catches young fish.

SALAMANDERS AND NEWTS.

All the varieties of those tailed batrachians frequent the water in
the spring, for the purpose of depositing their eggs or young — some
being viviparous, In all the stages of their growth, from the tad-
pole state to the perfect animal, these creatures are destructive to
both the fish eggs and the young fish, they should therefore be kept
out of the ponds.

The newts spend their entire life in the water. In certain
localities they may exist in such vast numbers that it is necessary to
take especial precaution to keep them away.

Neither of these creatures, however, is harmful to man, the larger
varieties living in the river, such as the water-dog and the hell-bender,
excepted, nor are any of them poisonous.

They may, with perfect safety, be handled with the bare hand.

As the season advances various other enemies, in addition to those
already mentioned, make their appearance. Most particularly must
a sharp lookout be kept for

WATER SNAKES.

These will be found concealed near the water’s edge, or in the
corners of the several ponds. They lie hidden from view, the head
THE GOLDFISH AND ITS CULTURE. 95

only exposed, all the while playing the tongue in the water. This
they do to allure their prey within reach, the fish mistaking it for a
worm rush to their certain destruction.

The best means of exterminating them is by the use of some kind
of fire-arm. A smooth bore, 22 caliber Flobert gun, loaded with a
cartridge containing shot, and a good marksman at the proper end of
it, generally makes a combination that forever prevents that snake
from exercising his fishing propensities.

If young snakes are about, they may easily be discovered by placing
pieces of board here and there about the ponds; these boards are
lifted up in the morning, often revealing two or three of the little
snakes that had sought shelter there, when thus found they are easily
despatched.

A good snake trap was accidentally discovered as follows:

A wire coop made of % inch mesh galvanized iron wire netting,
served as the dwelling of a couple of muskrats, which the children
kept as pets. These having died, the coop was used to confine live
frogs, and kept outside of the establishment in the water, just at the
point it leaves the ponds.

The next morning a large water snake was found caught in the
meshes of the wire, and dead.

It had evidently tried to get into the coop, and help itself to a frog
or two, and was thus caught, the wire preventing the entrance of the
entire body, the scales of the reptile at the same time precluding
the possibility of retreat. Since then this trap, and smaller ones,
have been used with very good results, and being simple they are
easily made.

Following the snakes, and at the time the ponds are filled with
water, one must be on the watch for fish-eating birds, among which
are
96 THE GOLDFISH AND ITS CULTURE.

CRANES AND HERONS,

which, seeing the surface of the water below whilst flying above, are
attracted by the glisten, and immediately descend to reconnoitre.
These birds visit the ponds at regular hours, wade in the water and
catch with consummate skill all the fish they can get. The fact that
their stomachs are sometimes found to contain nothing else than
crayfish must not mislead the amateur into the belief that they prey
only on these crustaceans, as the following fact abundantly proves
that they prefer fish whenever they can be obtained. A heron was
seen flying towards the ponds; to secure the ever-ready shotgun
from the lodge, sneak within range and fire, did not take more than
five minutes’ time. Yet within that short interval, the bird had cap-
tured and devoured three 234-inch long, brilliantly colored goldfish,
which, though already dead when taken out of the bird’s stomach,
were still perfectly bright, showing conclusively that they had just
been swallowed.

If these birds discover that fishing in the ponds pays well, they
will become frequent visitors, and, if not killed, soon clean out the
establishment. But, as before stated, they come at regular hours,
thus affording the one on duty at the ponds an easy chance to be on
the watch to kill or trap them.

THE KINGFISHER.

This bird may likewise be expected to visit the ponds, but it gen-
erally advertises its arrival with a lusty kar-r-r-r-r-ack! that may be
heard quite a distance.

It selects projections over the water, such as a branch of a tree,
a post, or the outlet pipe of the ponds, from whence it shoots down
upon the unsuspecting fish, seldom missing, It also supports itself
upon its wings immediately over the water, darting down upon its
prey with like success,
THE GOLDFISH AND ITS CULTURE. 97

These birds, although not so easily shot as the crane or heron,
may readily be caught in a trap, if the latter is somewhat concealed
and laid on the post or outlet pipe, which the birds mostly frequent.

TURTLES AND ALLIGATORS.

These reptiles are both extremely destructive; the latter, of
course, not being found in the Northern States, need not be looked
for in that locality. Neither of them, no matter how small, should
be permitted to remain in or near the ponds.

THE MUSKRAT.

Not only do these animals destroy the dams of the ponds, but
they will also destroy the entire stock of fish, if not stopped in time.
Luckily for the fish-culturist, they are easily mastered. One or two
muskrat traps of the old-fashioned style (Hawley & Norton’s No. 1),
used by professional trappers in the Far West, can be procured at
almost any hardware store for thirty cents apiece, the chain included.
The muskrat holes are looked for and will be found leading into the
bank and a little below the surface of the water. At a short distance
from such a hole (the length of the chain on the trap), a peg is
driven securely into the ground, and the free end of the chain.
fastened to it. The trap is then set wethout bait, and laid a little to
one side immediately into the hole, in such a manner that the animal
in going in or out is obliged to tread upon the plate that springs
the trap and over one or the other evd, thus it is always caught by
one of its legs.

If the trap is placed at right angles with the hole, so that the
animal has to walk over the bows, these latter, in coming together,
will throw the rat upwards, and fail to catch it.

It is advisable also to catch the muskrats in the surrounding
98 THE GOLDFISH AND ITS CULTURE.

neighborhood of the ponds, as they make excursions during the night
to the ponds in order to fish.

This long list of enemies may be increased by adding the raccoon,
the zk, and water-fowls such as ducks, geese, and swans.

In stores where fish are kept in tanks they must be watched and
protected from ouse-vats and cats, both of which will occasionally
make a descent upon the tanks if not prevented.

 
CHAPTER XXII.

THE DISEASES OF THE GOLDFISH.

 

The goldfish, when in perfect health, carries the dorsal fin in an
erect position, in other words, fully expanded. Its colors are very
distinct, the body of the fish glistening as though highly polished.
The fins appear very clear, translucent, allowing an examination of
their structure, they are also very flexible moving in the water with
animation and grace. When closed by the fish, the gill covers fit
tightly against the head.

Liveliness is not always an indication of good health, and, on the
contrary, sluggishness is no positive evidence that the fish is ill.

But when the brilliant red color fades away into an off-colored
pink, or the milky white portions of the body become intermixed
with bloody streaks, or the fins of the fish appear to be coated with
something unusual, or seem inflamed and stick together, or are carried
close to the body, or when the gill covers appear so swollen that they
will not fit tightly in their proper place, then the health of the fish
has failed, and danger is close at hand.

Most of the diseases of the goldfish are the direct result of ill
treatment while kept in captivity, and nearly always originate in the
breathing apparatus; the gills, when affected, fail to supply the blood
with oxygen. Some of the diseases, to which the fish are subject,
originate from improper methods of feeding, and always manifest
themselves in disturbances of the stomach, and other digestive
organs.

99
100 THE GOLDFISH AND ITS CULTURE.

Again there are diseases that make their appearance periodically,
the origin of which is involved in as much obscurity as that called
‘¢ pink-eye, ”’ which attacks horses, and of which all have heard more

or less.
ASPHYXIA.

This affection is the one most commonly met with. The fish
become weak, the colors fade away rapidly, the appetite is lost, and
the fish finally die if the disease is permitted to run its course without
hinderance

The cause of the disease may be looked for in the interrupted
functions of the gills. These organs become inflamed by the irritat-
ting and poisonous gases that may exist in the water, or by the sudden
changes of temperature in the same.

If the disease has not already advanced too far, the ailing
individual or individuals, should be taken from the collection, placed
in a vessel containing a sufficient quantity of water, and in which a
number of flourishing aquatic plants are growing.

An even teaspoonful of common salt is then dissolved: in the
water, the whole then put in a light, well ventilated place, and kept
at a temperature between 70° and 80° F, During the first few days
no food is necessary, and should not be given, after which the
feeding may be re-commenced, beginning with very small quantities,
administered at a regular hour each day. As the fish brighten up,
and approach convalesence, the quantity may gradually be brought
up to the usual amount.

TUBERCULOSIS OR CONSUMPTION.

The first sign of the presence of this disease shows itself in the
indifference manifested by the affected individual. They are seen
swimming about in a careless, purposeless way, now and then
THE GOLDFISH AND ITS CULTURE. Iol

stopping to make the vain attempt to remove something from their
gills that annoys them. They are apparently coughing. Their
appetite decreases. It is evident that the gills are out of order,
they thus failing to take up oxygen for the blood.

As the disease progresses the fish becomes lean, as seen back of
the head, on the back, and the sinking in of the abdomen, causing
the head to appear too large and out of proportion. The gills
become agglutinated which results in the destruction of their
structure by decay. Having arrived at this stage the fish is too weak
to balance itself and swims head downward, finally standing on it,
because it is the heaviest part of its body, and dies in that position.

The duration of this disease varies in different individuals and
seasons, it being of shorter duration during cold weather.

The origin of this disease may be traced back to unnatural
treatment while in captivity, as fish in native waters never get it, and
in well managed aquaria they very seldom have it, while in those
badly managed they frequently die of this disease. The cause of
the disease arises from invisible organisms called ¢ubercular baccille,
these being inhaled by a fish whose breathing apparatus is in the
least out of order, infest these organs and destroy them.

The disease proves fatal in all cases, or has invariably done so in
the writer’s experience, who has so far failed to discover an effective
remedy. The disease may be avoided by keeping the aquarium in
perfect condition.

SLIME OR ITCH.

This disease generally appears during the colder season of the
year, seldom manifesting itself when the weather is warm or hot.

The body of the fish becomes coated with a layer of some whitish
substance, the deposit beginning on the back near the head.

This white, slimy substance, when examined under a powerful
102 THE GOLDFISH AND ITS CULTURE.

microscope, reveals a number of parasites darting about hither and
thither across the field of the instrument, These minute organic
bodies, technically termed dacteriz, resemble a wood-tick in general
shape. They appear to eat into the skin of the fish, destroying that.
structure, and in consequence interfere very much with the function
the skin performs in throwing out poisonous substances that form in
the tissues inside. The beautiful colors of the fish disappear from
the tainted parts, they becoming quite black. The result of the
disease is the death of the fish.

When afflicted with the trouble, the fish can be observed rubbing
itself against the plants, the rocks, or in the sand upon the bottom of

the aquarium.

The cause of the disease may be found in the usual over-feeding,
in which case the remnants of food remain in the water until decom-
position sets in. The temperature not being favorable for the pro-
duction of water-purifying insects, the Jacterie make their appearance
greatly to the detriment of the fish.

The name ‘‘slime” has heretofore been applied to this description
of disease, but without any apparent reference to the cause producing
the trouble. In the author’s opinion, it is the presence of the para-
sites that makes the whole difficulty. They annoy the fish by their
presence, their attacks upon its skin setting up an increased flow of
blood to the part upon which the thick coat of slime is found.
Manifestly the best method of treating the disease is the removal, or
rather the prevention, of the cause, for if the dacterie are not allowed
to develop, they of course can do no harm.

Tadpoles and snails should be put into the aquarium to consume
any remaining particles of food, and the feeding itself more carefully
attended to. Place the aquarium in a warm and light location,
adding to the water a pinch of table-salt when filling the vessel.
THE GOLDFISH AND ITS CULTURE. 103
DROPSY.

Dropsy, as every one knows, is a swelling up of the body, caused
by the presence of watery fluid in the tissues, so it is with fish when
affected in this way.

It generally begins near the tail, but sometimes about the middle’
of the body and progresses forward. When it first makes its appear-
ance, afew scales in a circle around the body lose their firm attach-
ment, at this stage, if the affected specimens are immediately removed
and placed into water brought from some other locality than that in
which they had been when taken ill, they will recover in a short

time.

The disease having started, will, if not immediately attended to,
spread over the entire body until it becomes almost spherical, so
great is the distention of the skin. The scales become erect, giving
the fish the appearance of a ‘‘ruffed grouse,’’ the eyes at the same
time being greatly protruded from their sockets.

During all this while the fish shows a good appetite, and con-
tinues to do so until the end, which soon follows.

No cause, as yet, has been found producing the disease; it
appears upon fish in Europe, as well asin this country, and also upon
fish kept in open air ponds, as well as those inhabiting the aquarium,
and in any season of the year, and at any age of the goldfish.

The disease may run a course of four months, at the end of which
time it results in the death of the fish. It also seems to be intermit-
tent in character, disappearing for several weeks, and returning
again upon the same individual, but always in such cases with fatal
effect.

There seems to be no other treatment than making the fish as
comfortable as possible, taking that chance for recovery.
ro4 THE GOLDFISH AND ITS CULTURE.

ERYSIPELAS.

This disease is indicated by what appears to be a nervous rest-
lessness of the fish. They are seen swimming with very quick
motions, darting here and there with great rapidity, and with no
other apparent reason than a desire to flee from their torment, for it
seems that they suffer from muscular pains. After this extreme
activity which covers a period of several days, the fishes (for they
all become affected at the same time) huddle together on the bottom
of the tank, now and then resuming their mad capers.

The external appearance in this case is characterized by a closed
dorsal fin, bloody streaks upon all of the fins, which, moreover,
instead of being nicely rounded upon their extremities, as in health,
become agglutinated and appear like the spikes upon a catfish. The
tissue between the spines decays, the latter looking like the disar-
ranged bristles on a brush; this is the beginning of the end.

The appetite continues in good condition, the fish, nevertheless,
become lean and weaker each succeeding day until death takes place.

The cause of the disease, also, can be traced to improper
methods of feeding, the stomach in consequence becoming over-
taxed and the entire system disarranged.

When it does appear, all the fishes are attacked at the same time;
the aquarium then should be placed where it will be exposed to the
sunlight, the temperature of the locality being kept at about 70° F.,
and no food administered for about a month. Snails and tadpoles
should not be omitted when stocking the hospital tank, as they are
excellent scavengers, and by their presence will prevent a complica-
tion of diseases.

The diseases described above constitute the main ones we have
to expect, and, with the exception of dropsy and tuberculosis, are
easily managed, if the treatment is carried out properly.
THE GOLDFISH AND ITS CULTURE. 105

ACCIDENTS.

According to the old saying, ‘‘accidents happen in the best reg-

>

ulated families,” so will they happen to goldfish. In most cases,
nature, if let alone, will repair damages with surprising skill, though
a little assistance often helps to secure a desirable result. Scales
that have been knocked off will be replaced, just as a finger-nail is
when bruised.

Injured fins grow again, but the form afterwards does not always
assume perfection.

If an eye has been torn out, it will not necessarily kill the fish,
as in most cases it heals kindly, and indeed might (for appearance’
sake) be replaced by an artificial substitute, such as are in use by the
taxidermist.

When we wish to assist nature to heal a wound, we must bear in
mind that a warm temperature is most favorable for that purpose, and
is also not favorable for the growth of fungi, which would certainly
collect on the wound and reduce the chances of complete recovery.
As an additional guard against the formation of fungus, table-salt in
quantities mentioned above in treating asphyxia, is good, as also is a
solution of carbolic acid, five drops to the gallon of water.

We conclude this description of the various diseases with the
homely phrase, ‘‘an ounce of prevention is worth a pound of cure,”
so bearing that in mind, one will see to it that his aquaria and ponds
do not suffer from neglect, as that always tells upon the fish.
CHAPTER XXIII.

REQUISITES AND TOOLS.

 

Not many of these are necessary for the raising of goldfish. In
addition to the ordinary gardening tools used in constructing and
repairing the ponds, four sizes of dip-nets should be kept near at hand.

ist. A large one consisting of a heavy iron wire ring, about the
thickness of a lead-pencil, and measuring about fifteen inches in
diameter. This ring is securely fastened to a hickory pole seven feet
in length, and covered with heavy mosquito netting, the bag to be
about twelve inches deep. .

and. A medium-sized dip-net of oval shape, measuring six inches
by ten inches through the center. This is best made of No. 10 brass
wire, fastened to a handle four feet in length, and covered with finer
mosquito netting, forming a shallow bag similar to the bowl of a
spoon. This net is used to remove insects and small fish from the
water.

3d. A hand-net of the same size and material as No. 2, with this
difference, that the handle may be made of the same wire that forms
the frame.

4th, A small dip-net, also made of brass wire, No. 16 or 17, in this
case of sufficiently small size to use in removing fish or insects from
the hatching-jars.

Several one-gallon candy-jars for hatching the eggs; several tin
buckets of different sizes, for carrying and removing fish; a yard or
two of mosquito netting; some wire netting of the same mesh as that
used in the guards on the outlets; a thermometer, a couple of musk-
rat traps, if needed, and a gun to dispose of snakes, birds, etc.,
complete the outfit that is necessary for the proper performance of

the work in hand.
106
CHAPTER XXIV.

PROFITABLENESS OF GOLDFISH PONDS.

 

The question will naturally arise in the mind of the reader, should
he have any desire to engage in the culture of the goldfish, ‘‘ Will it
pay?” ‘‘ Are the profits accruing sufficient remuneration for the time
and labor expended, to say nothing of the capital invested?” To
these questions the best answer is the book upon which the author
has expended so much time, for he is certain that the proper cultiva-
tion of the goldfish will pay, though there are some considerations,
the absence or presence of which somewhat determine the result.
If looked at from a business point of view solely, it wholly depends
upon the local demand for them, though more especially upon
the class of customers one is expected to supply. In some places
the finer qualities and varieties pay best, as the demand for them
comes from a source that is both discriminating and critical, at the
same time willing to pay for the very finest that can be had. Sucha
market is usually found in the larger cities where the wealthy classes
generally reside, and it is from among them that the culturist may
expect to find a ready and remunerative run of custom. In other
places the demand is for quantity not so much care being taken
whether the varieties are the best or not; for instance, a gentleman
wishes to stock a lake upon his premises or in his garden with orna-
mental fish, he does not care especially to invest his money in a few

choice varieties, but would rather have a greater number of a less
107
108 THE GOLDFISH AND ITS CULTURE.

desirable kind in order that the lake or pond may contain them in
plenty, so that they can always be seen, no matter from what poini.

The percentage of young grown to perfection from a given num-
ber of eggs depends altogether upon the attention paid to them, the
locality in which they are raised, the season in which they are bred,
and the variety to which they belong. The number of saleable fish
may thus be but ten, or it may be eighty-five, realized out of one
hundred eggs. The rules governing the productiveness of ponds are
much the same as those that govern the crops raised from the soil.

There is this difference, however, the raising of goldfish is confined
almost exclusively to the nicest season of the year, and makes it a
highly interesting out-door recreation, and one that can be begun on
