ALBANY, N.Y. (AP) — New York environmental protection officials are reporting success in efforts to control sea lamprey populations in Lake Champlain.
The state Department of Environmental Conservation announced Wednesday that lamprey-killing chemical treatments conducted last year on several of the lake’s tributaries in New York and Vermont have improved conditions for landlocked Atlantic salmon and lake trout.
The treatments by the DEC, in coordination with the U.S. Fish and Wildlife Service and the Vermont Department of Fish and Wildlife, are meant to kill lamprey that attach themselves to other fish, often killing the host fish.
The control program also benefits other fish species including northern pike, walleye and lake sturgeon.
DEC officials say the treatment program will continue to benefit the lake’s fish population this year. The agency first began combating lampreys in Lake Champlain in 1990.
