Dams and canals also damaged the fish stock thus the need for Fish Hatcheries , particularly anadromous species that migrate between salt and fresh waters. Over fishing was wild. After industrial pollution, urbanization, as well as the launch of nonnative species further undermined the state’s waterways.
What are Fish Hatcheries
Hatcheries generally keep a brood stock of mature fish from which to get eggs for propagation. Eggs and milt may also be “milked” or “stripped” from wild fish netted in waters around the state. This usually means softly squeezing mature fish to discharge the eggs or milt, subsequently returning the fish to the water unharmed.
The gametes are taken to the hatchery and combined together under certain conditions. Fertilised eggs develop into “sac fry” in hatching jars and are subsequently transferred to raising units till they reach “fingerling” size, 3-5 in (8-13 cm) long. Most fingerlings are stocked in the springtime, but yearlings of some species may be published in the fall. Fry can be sent either in plastic bags full of oxygenated water or in bigger, oxygenated tanks mounted on trucks. Fingerlings are transferred by hand to tanks on the stocking trucks.
The earliest fish hatchery in New York State (and in America) is the Caledonia State Fish Hatchery in Livingston Co. It opened in 1864, founded by Seth Green (181788), “the dad of fish culture,” who was unnaturally propagating brook trout since 1837. By 1870 the Caledonia hatchery was being run by the state. Green introduced rainbow trout to New York from California in 1874 and additionally worked on raising shad generation. He ran a shad hatchery on the Hudson in the 1870s and is credited with fostering supplies of shad in the Hudson and other northeastern rivers.
Selected fish commissioner for New York State in 1868, a year after Green became the state’s first superintendent of fish culture. Fred Mather started to hatch various species at his farm in Honeoye Falls (Monroe Co) in 1868. He was likewise active in the propagation of shad in a number of states. He successfully hatched salmon in Roslyn [now in Nassau Co] for release in the Hudson River. In 1883 he imported brown trout eggs from Germany and was made superintendent of the state’s Fish Commission Station at Cold Spring Harbor (Suffolk Co), which created hatches of lobster, cod, and other marine animals.
Private citizens quickly took up the practice of aquaculture, and in 1870 the American Fish Culturists’ Association was formed in Nyc. Its members experimented with feeding, breeding, and restocking techniques, management of fish diseases, successfully recommended for international removal of barriers impeding fish migration, and lobbied Congress to produce the US Commission of Fish and Fisheries (1871).
In time several fish hatcheries, both private and state, would be created in New York State. In 2003 the New York State Department of Environmental Conservation (DEC) ran 12 hatcheries and one fish pathology lab, which generated about 900,000-1,000,000 pounds (408,000-454,000 kg) of fish. That supply replenished over 1,200 public streams, rivers, ponds, and lakes in 57 counties. The fish were used mainly for recreational purposes, but hatcheries additionally restored native species to their first habitats.
In 2003 a number of DEC hatcheries were creating various brown, rainbow, and brook trout: Caledonia, Bath (1893; Steuben Co), Chateaugay (1925; Franklin Co), Rome (1932; Oneida Co), Randolph (1933; Cattaraugus Co), Van Hornesville (1935; Herkimer Co), and Catskill (1948; Sullivan Co). Varieties of salmon, including Atlantic, coho, and chinook, were raised at hatcheries at Adirondack (1885; Franklin Co) and Salmon River (1980; Oswego Co).
The Oneida (1897; Oswego Co) and Chautauqua (1943) hatcheries increased walleye. The South Otselic State Fish Hatchery (1932; Chenango Co) raised tiger muskellunge. Uncommon species including tradition form brook trout, paddlefish, pure form muskellunge, splake, temiscamie, and lake sturgeon were also cultivated at several sites.
The Rome Fish Disease Control Center conducted research and diagnostics, with a specific concentrate on the parasite that causes whirling disease. All DEC hatcheries are open to the general public at specified days and hours through the year. In 2003 there were 40 in private run hatcheries licensed to manage. The hatchery at Cold Spring Harbour, created in 1883, became a not-for-profit aquatic instruction facility specialising in freshwater ecosystems in the 1980s.
