‘Milestone’ Fish Found in New York Lake For 1st Time in Over 60 Years
New York officials say this is a "significant milestone."
On Wednesday, New York State Department of Environmental Conservation Commissioner Basil Seggos today announced a significant milestone for lake trout rehabilitation efforts in Lake Erie following the confirmed identification of wild fry collected by DEC's Lake Erie Fisheries Research Unit for the first time in over 60 years.
The discovery of wild lake trout fry is a historic restoration indicator for a population that was once plentiful but collapsed due to overfishing, habitat degradation and invasive species, officials say.
"Today marks a key milestone in the restoration of lake trout in Lake Erie after six decades of significant investments to improve water quality and habitat and promote sound fisheries management," Seggos said. "This phenomenal Great Lakes story of recovery is a testament to the perseverance of the researchers and biologists from DEC and partner agencies who worked tirelessly to help restore this fishery."
The recent discovery is the result of an acoustic telemetry study, conducted by DEC expert staff and partners, which identified potential lake trout spawning areas in eastern Lake Erie.
Lake trout were once the top predator in Lake Erie with records of fish measuring in excess of 50 inches and weighing 75 pounds. Commercial fishing for lake trout in Lake Erie began in the late-1700s, and by the late 1800s, the population had significantly declined. By the 1930s, the commercial fishery had all but ceased, and by 1965, lake trout were considered extirpated from Lake Erie. Modern-day efforts to restore lake trout began in 1982, with annual stocking by USFWS in partnership with DEC and PFBC. In 1986, the Great Lakes Fishery Commission began suppressing the invasive sea lamprey population to support lake trout rehabilitation efforts. The sea lamprey is a parasitic jawless fish that feeds on other fish by attaching to them using a suction-disk mouth filled with rasping teeth and a file-like tongue.
Recently, biologists determined that adult lake trout stocks had improved to a level at which natural recruitment could be detectable. Although the number of wild lake trout fry collected earlier in 2021 was small, the discovery of evidence that lake trout are spawning and their eggs are surviving and successfully hatching is historic. Following decades of research, this finding validates that restoring wild lake trout populations is attainable. Biologists conduct annual assessments of the population in the eastern basin to measure progress toward rehabilitation goals.
