Using technology to monitor lake menace Presque Isle County Advance (4/10) The Hammond Bay Biological Station in Millersburg, Mich., is working with the United States Fish and Wildlife Service on a new fish observation system to monitor sea lamprey as well as other fish species.
Sea lamprey public enemy No. 1 among invasive species Northumberland Today (2/25) Of all the invasive species threatening the Great Lakes, public enemy number one remains the sea lamprey, as no other species has caused more damage to the lakes and the lakes’ tributaries.
Ohio attempts to restore trout species to Lake Erie WEWS-TV - Cleveland, OH (1/3) The Ohio Department of Natural Resources has announced a pilot restocking plan to return lake trout, a species of concern due to sea lamprey predation and pollution, to Lake Erie.
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.
This series of pictures shows a close-up of a lamprey's mouth, lampreys attached to a lake trout, and the damage resulting from a lamprey attack.

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.
