GREEN, Seth, pisciculturist, born in Rochester, New York, 19 March, 1817. He received a common-school education, but early manifested a passion for hunting, fishing, and woodcraft. For many years he was the proprietor of the only fish and game market near his home. In 1837 he conceived the idea of the artificial propagation of fish, and in 1838, during a trip to Canada, made observations on the habits of salmon. Observing that as soon as the spawn was cast the male salmon and other fish ate it, he devoted his attention to methods of protecting it, and increased the yield of fish till he had raised the product to ninety-five per cent. In 1864 he discovered a method of artificially impregnating dry spawn, and began the propagation of fish as a business at Caledonia, Livingston County, New York In 1867, by invitation of the fish commissioners of four of the New England states, he experimented on the hatching of shad at Holyoke, on the Connecticut River, and by his improvements hatched in a fortnight's time 15,000,000, and in 1868, 40,000,000. His work was afterward extended to the Hudson, the Potomac, the Susquehanna, and other important rivers, where he succeeded in artificially propagating fifteen of the more common species with largely increased products. In 1868 he was appointed one of the fish commissioners of New York, and soon afterward made superintendent of fisheries in that state. He transported in 1871 the first shad ever taken to California. As a result, over 1,000,000 marketable shad were sold on the Pacific coast in 1885. He has hatched artificially the spawn of about twenty kinds of fish, and has also hybridized striped bass with shad, shad with herring, brook trout with salmon trout, brook trout with California salmon, salmon trout with white-fish, and European trout with American brook trout. He has been decorated with two gold medals by the Societe d'acclimatation of Paris. He has invented important appliances for use in hatching shad, trout, and other fishes, and is the author of " Trout Culture" (Rochester, 1870), and "Fish Hatching and Fish Catching" (1879).
