f // 3sr /^y SH J3 .N8 W7 t Copy 1 FISH CULTUEE 2rrjE3: CJk.K;OLiisrj^. 3^,f4/ ■>. PREFACE. In presenting the report of S . G. Worth I call attention to section 7 of the Act creating the Department of Agriculture which charges the Board especially '-With the suj)ervision of all measures for the protection, propagation and culture of fish in the rivers and other inland waters of this State, and to this end they shall at once provide for stocking all available waters of the State with the most approved breeds of fishes." Though this Act was not ratified till as late as the 12th day of March, 1877, the services of an expert were secured aud a corps of young men of this State as assistants were stationed on Neuse river and the hatching of shad began. Prevailing freshets and diminutive run of shad interfered with full success of the work. Since that very great success has been attained not only in the propagation of shad but also in the propagation and intro- duction of California salmon, land-locked salmon and brook trout. For the propagation of the latter varieties a cheap hatch- ery was built at Swannanoa Gap in Buncombe county, and two seasons of winter work have been completed. The results are embodied in the accompanying report. Commencing only two years ago without a shad box, distri- buting can, or the least preparation of the necessary apparatus used in fish culture, or without a man in the State who knew the principles of the work, the peojole of the State may congrat- ulate themselves on what has been attained. I would especially note here that every effort has been official- ly made to prevail upon the authorities of the State of South Carolina to enjoin upon their Legislature to enact co-operative laws that our people might secure a partial benefit from the fish of streams running from this State into that. I regret to say that not the first response has ever been made. The salmon (4) being more perfectly adapted to the Yadkin, Catawba, Broad and Green, over 300,000 have been placed in those waters. Without laws prohibiting permanent obstructions and a whole- sale destruction of the fish south of our State line, it will be necessary to discontinue the release of more fish in those streams. It would not only be foolish to pursue our operations there, but unfair and unjust. It would be a repetition of the abuses on the Connecticut river where money was expended by New Hampshire, Vermont and Massachusetts and the shad increased seven times their former number, while the peo2:)le of Connecti- cut on the lower waters reaped almost the entire benefits. In the laws of Virginia they will make an exception of such streams as run into our State unless we remove the obstructions. They will place no fish into streams running into this State unless ob- structions to the passage of fish are removed and fish-ways or other means of crossing dams provided. So I am informed by the Fish Commissioner of that State. If proper laws are not enacted by our Legislature toward the protection of fish it will not and shall not be the fault of the Board under which I act. In my recent report to the General Assembly which received the unanimous approval and recom- mendation of the Board, I entered into the details and offered such recommendations as seem to embrace all the requirements to subserve the wants of the people of the State in this interest. The operations of the last two years have demonstrated the en- tire practicability of filling to its utmost capacity every stream in the State. One per cent, of the salmon released in this State are worth more than our entire out-lay has been, and one per cent, of the shad released at twenty-five cents apiece would bring over nine thousand dollars. From one end of this State to the other streams cover its face like a net-work, evincing the fact that the fishing interests can be made one of our greatest in- dustries. Successful demonstration proves that one acre of water in New^York State is more productive than several acres of land, hence any future policy in our governmental affairs which fails to take hold of our natural advantages and restore their (5) productiveness will fall short of the progressive strides of the day. Without depending on the uncertain aid of foreign experts whose time is elsewhere in demand, we have trained young men who were born and raised here in our own State who are fitted for doing all the work within our own borders. We need friendly and fostering legislation and with the re- commendations before them it remains for the General Assem- bly now in session to act. L. L. POLK, Commissioner of Agriculture. REPORT. Koi(. L. L. Polk : Sir :_ln accordance with your request I submit below the operations in Fish Culture in North Carolina since April 1st, 1878. My immediate presence in the execution of all the work done since that date, has given me the advantage of innumera- ble facts which bear directly on the future of this work. But I have written to you frequently as new points developed, and in numerous conversatione have so fully set forth the needs and requirements that were pressing, that 1 will not attempt to en- ter all of the details in this report. This art is so new that very few among us have had an opportunity of looking into it suffi- ciently to know its requirements or to pass judgement on past o erations. Hence, I infer, is due the honor your honorable Board has bestowed on me in leaving the execution and the de- tails of the work entirely in my hands. During the past twelve months, ending the 1st of April 1879, we have released in the North Carolina waters over three and one-half millions of young shad, three hundred thousand California Salmon, fifteen thous- and five hundred Land-locked Salmon from Maine, and fifty thousand Mountain or Brook Trout. All of this was done at an expense of less than three thousand dollars, and among the ex- penditures was a sum of not less than five hundred dollars in permanent structures and hatching and distributing apparatus, tools, &c., now on hand, including all salaries. This sum when compared with results will bear favorable comparison with similar work done any where on the globe. To convey an idea of the immense returns in fish culture, I will make a statement which may surprise you. California Salmon attain an average weight of 20 pounds, and sell readily at twenty-five cents a pound. If we suppose that ninety-nine per cent of the three hundred thousand hatched this season are never heard from and (8) that the one per cent which do return attain the average weight of other waters and bring a price of five cents a pound, the Sal- mon of the past season alune will more than pay the expense of the whole season, including the Shad, Land-locked Salmon and Trout. The immense losses in the eggs and fry offish seems to have been a great foresight of nature in giving to them the gieatest ow^beariug powers of any of the vertebrate animals. A 40- pound Salmon produces 30,000 eggs annually; the Yellow Perch (Raccoon Perch or Red-fin Trout) 20,000 to 30,000; AVhite fish of the Great Lakes 60,000 to 70,000; Shad 30,000; Carp over 300,000; Mackerel over 500,000; Turbot and Cod about 9,000,000; Sturgeon 7,000,000, and a species of Mullet 13,000,- 000 ! These figures are from scientists and fi^h-culturists, and an annual value of the fish-catch of the world, amounting to $120,000,000, will convey some idea of the millions and millions of eggs annually produced Irom a mass of fis?h aggregating so many millions of dollars. On examination of the nests of the California Salmon it is found that only eif/ht yter cent ot the eggs are impregnated. By the artificial method of inipregnaHon we secure ninety to ninety-five per cent ! After impregnation by the natural method the eggs are left a prey to enemies of innu- merable numbers. Shad eggs are exposed thiee to five days, and our common pond fishes twenty to thirty, and the Salmon fifty to seventy. After hatching, these fish are helpless, some a few days, (shad a week) some for months as in the case of Salmon, Mountain Trout and fall-spawning- fish generally. By the arti- ficial methods they are not only almost entirely impregnated, but they are kept in cones, troughs and other vessels, and each day the dead removed and further communication of fungoid growth stopped. And when the young are ready to go out they are conveyed to head streams, where other fish are scarce and where cold water suppresses the numerous hosts of insects and crustacenas that abound in the lower and warmer waters. We can see readily, that feiv arrive at maturity, when we recall that one single sturgeon produces seven million eggs and that a num- ber less than ten thousand are taken annually in the Cape Fear. Few realize the value of fish, but a moment of reflection will show that they cost us nothing, and that by replacing them in (9) the waters by aiding their imperfect efforts we restore to our land at a nominal cost its millions of wealth that our streams annually bear away to the ocean. Who knows the value of the constituents of our gliding rivers, and by what means can we reclaim it ? By the judicious expenditure of a few thousand dollars annually we can attain it. If our people look tins year for any return from what has been done, they must remember that the patient farmer sows his seed and waits till they have had time to develope and mature. No shad return in one year, and indeed no roe shad ever returned to fresh water till the third year. Long ago fish became scarce as the population of Europe in- creased and fish culture there is an estaUished thing. Millions of fry are annually liberated from their hatching houses, and such judicious laws have been made as to foster and protect them. In Great Britain a river yielding in 1853 less than 2,000 Salmon was made to produce in 1866 upwards of 20,000. The Tay then leasing for 143,500 came up in 1866 to 175,000; and in Ireland in 1866 one thousand tons of Salmon were transported against almost none ten years previous. In the United States we find shad now flourishing in the Sacramento river in Califor- nia, where they were unknown till placed there in 1871. The first results seen on the Connecticut from artificial propagation of shad increased the usual catch seven fold. Twenty-five thousand shad were taken in one locality one morning and the Northern markets were overstocked and the price of eighteen dollars per hundred reduced to three ! In that river the Sal- mon had entirely disappeared, but in 1872''73 fry were intro- duced and since that time sufficient numbers of 12 to 18 pounds weight have returned to justify increased operations. The fruits of past work are also being seen on the Delaware, Susque- hanna and all other streams where the fish have had time to ma- ture and return. On the Merrimack a dam of 25 feet height completely cut off the passsage of Salmon to their spawning grounds, and for thirty years not one was seen, but by introduc- ing the fry from other streams they have found that upwards of (10) one thousand went over the fishway on the same dam in the first year of their return. Propagation by the artificial method is an outgrowth of neces- sity. A hundred years ago every stream from the St, Johns to the St. Lawrence teamed with its thousands of shad. To-day they bave become so scarce that we are compelled to resort to the largest fisheries in the land to obtain enough spawn to make our work profitable. In the absence of any data relative to the run of shad in our own waters in former days, I will state that the catch of shad on tlie Potomac in 1835 was 2'? 500,000, which contrasts severely with any season approaching the jiresent. The alarming decrease in numbers of fish, when brought before the Congress of the United States and fully impressed, at once led to the creation of a commission for the purpose of enquiring into their decrease, and for the institution of measures for their increase and protection; hence originated the United State Commission of Fish and Fisheries which has been the great mo- tive power and educator in this branch ever since. Twenty- seven States are now actively engaged in resto.;king their waters, and I am glad to say that with limited means we have made & very decided beginning in North Carolina in two short years. With the finest sliad fishing grounds in the world, and many secluded mountr.in streams yet full of trout we are ful- ly capable of su])])lying every county in the State with as many fish as the jjcoplc can consume. In view of the fact that the shad caught in our waters sell in northern mar- kefs before the rtm of fish has extended into their streams, and since our sales there bring double the price of theirs by sup- plying the early demand, it is very plain to be seen that in re- stocking our sounds and rivers to ten times their present capac- ity^, we can supply every demand at home and bring into our State thousands of dollars from aljroad. As the truck-farms of the south are annually reducing the value of like products on those further nortli, in sui)plying tlie ready demand for early vegetables and fruits, so will the fisheries of Albemarle sound and other Avaters, in like manner reap large cash sums of money from northern markets if the millions of eggs now an- (11) ■Tinally wasted on the sein beaches, are only hatched and cared for. The taking and hatching of the many millions of eggs \ y the United States Commission last season, was simply saving the millions, not one of which would otherwise have produced a fish, SHAD. Early in April, in compliance with instructions from you, I repaired to the Albemarle Sound, with a few assistants to work in conjunction with the United States Fish Commission, that of the State of Maryland and that of Virginia.
