New York's Salmon River Fish Hatchery and Oneida Lake Fish
Cultural Station are among the most modern facilities in North America.
The Salmon River
in Altmar produces about four million trout and salmon each year to help make sportfishing
opportunities in New York among the best in the world. The Oneida Lake Fish Cultural Station
in Constantia is the largest, state-of-the-art walleye hatchery in the country and the first facility in
North America intensively rearing large numbers of fingerling walleye.
The Salmon River Fish Hatchery, which began operation in 1981, is part of a major effort by
the New York State Department of Environmental Conservation (DEC) to meet stocking needs
Lakes Erie, Ontario and Champlain and their tributaries. The hatchery raises 250,000 coho
3.2 million chinook salmon, 600,000 steelhead, 200,000 landlocked Atlantic salmon, and
brown trout each year.
The Oneida Lake Fish Cultural Station was renovated and expanded in 1993, and is the most
modern facility of its kind. According to recent DEC statewide angler surveys, walleye ranks
after bass and brown trout as the most sought after fish. The facility's capacity is 400 million
producing 200 million fry and 250,000 to 300,000 4-inch to 5-inch fingerlings.
At one time, Lake Ontario supported the largest population of
lake-dwelling Atlantic salmon known to man, while both Lakes Erie and Ontario were excellent
trout fisheries. However, by 1900 the salmon had vanished. By 1950 the lake trout had also
disappeared from most of the Great Lakes. What happened? Destruction of habitat, over fishing,
predation by an exotic parasitic fish called the sea lamprey, and numerous dams which prevented
salmon from reaching spawning streams all led to the disappearance of these spectacular
Human disturbances and over exploitation also resulted in the substantial loss of the walleye
population in New York's waters. Walleye is a highly popular sport fish due to its excellent
quality. The Oneida Lake Hatchery's purpose is to increase walleye population in 89 existing
Through the work of the two hatcheries, world class sports fisheries have been created in the
waters of New York and the Great Lakes.
The hatchery operations are based on the reproductive cycles of
trout, salmon and walleye. Each fall chinook and coho salmon from Lake Ontario swim up the
Salmon River, then Beaverdam Brook, and finally up the ladder to the Salmon River Hatchery.
to three years earlier, these same fish were released from the hatchery smolt pond and swam
the same route to reach Lake Ontario.
During spawning operations, eggs and milt from adults are combined to start a new
Up to nine million salmon eggs can be incubated at one time at the Salmon River Hatchery. The
hatch after about one month and are transferred to "start tanks" after they have absorbed their
sac, about one month later.
While in the start tanks, the young salmon, now called fry, grow to about three inches in
and are then called fingerlings. Chinook salmon are stocked at this size, about six months after
hatching. Coho salmon are raised an additional year in the outdoor raceways and released the
following spring, at about five to six inches long.
Steelhead, which spawn in the spring, are also raised at the Salmon River Hatchery and are
stocked at about one year of age. Brown trout and landlocked Atlantic salmon, which spawn in
fall, are transferred in as fingerlings from other hatcheries and raised until about 14 months of
Trout and salmon raised at the Salmon River Hatchery are trucked to stocking sites and
released into tributaries, harbors or directly into the lakes. Once in the lakes, the young fish grow
rapidly. Chinook salmon in Lake Ontario, for example, may exceed 40 pounds after five
summers, while brown trout and steelhead may exceed 20 pounds. The current Great Lakes
record chinook (47-pounds, 13-ounces) and world record coho (33-pounds, 4-ounces) were
caught in the Salmon River during their spawning run to the Salmon River Hatchery. When
mature, salmon and steelhead return to the stocking site to spawn. Those released directly from
the hatchery return to it to start the cycle again.
Adult walleye are collected in 20-25 trap nets set in Oneida Lake. They are transported to the
Oneida Lake Hatchery in boats and placed in adult holding tanks. Here, the walleye are hand
as to male, ripe female (capable of being stripped on day of collection) or hard female (to be held
for later stripping). To collect the 400 million eggs the hatchery needs, over 40,000 walleye are
handled each year. This process usually occurs in an 8 - 14 day period during the first week or
of April. Fingerling rearing begins after the 21 -day egg incubation period when newly-hatched
are ready to be fed brine shrimp. After consuming brine shrimp for 40 days, the walleyes are then
switched to a formulated diet, reared for 100 days or more, and are released at four to five inches
The Oneida Lake Fish Cultural Station will help in the restoration of self-sustaining and
abundant walleye population in 33 waters. The hatchery is also trying to introduce and establish
walleye populations in 21 waters.
The Salmon River Hatchery is open to the public from 9 a.m. to
p.m. seven days a week from March 15 to November 30. Informative exhibits, including
and live fish, introduce visitors to fish hatchery operations and the DEC's Great Lakes
Program. A self-guided tour allows visitors to watch hatchery operations. Depending on the time
year, visitors may observe fish swimming into the hatchery, the egg taking process, and fish
Most people enjoy visiting the hatchery during the spawning seasons -- Salmon spawn in
October and steelhead spawn in late March/early April. You may call the hatchery in advance of
your visit to find out which activities are in progress. Approximately 200,000 visitors view the
