Sea lamprey (Petromyzon marinus) are predaceous, eel-like fish native to the coastal regions of both sides of the Atlantic Ocean. They entered the Great Lakes through the Welland Canal about 1921. They contributed greatly to the decline of whitefish and lake trout in the Great Lakes. Since 1956, the governments of the United States and Canada, working jointly through the Great Lakes Fishery Commission, have implemented a successful sea lamprey control program.

Sea Lamprey Control Program Great Lakes Fishery Commission The GLFC's program of integrated sea lamprey management includes lampricide control, construction of barriers in streams to deny sea lampreys' entry, and an experimental program to reduce spawning success by releasing sterilized-male sea lampreys. The program has successfully allowed the re-emergence of the largest freshwater fishery in the world.
