Atlantic Salmon

Atlantic Salmon

Salmo salar

Atlantic Salmon migrates into northern coastal rivers from the ocean. It also lives in inland lakes where it became landlocked; these populations may be native or introduced by hatchery stocking programs. Dozens of tributaries of Lake Ontario, the Finger Lakes, the Saint Lawrence River and Lake Champlain had landlocked spawning runs until the 1800s when dams that blocked migration, pollution and over fishing caused declines leading to eventual extirpation in these watersheds. Stocking programs have supported fisheries in 13 watersheds but recruitment from natural spawning remains low.
