What's New GLFC's new online video database (10/31) This week, the Great Lakes Fishery Commission launched an engaging, open-access video database on its website. The videos, available streaming and in HD, chronicle sea lamprey in the wild, sea lamprey spawning, various aspects of the sea lamprey control program, and cutting edge fisheries research.
How to beat the sea lamprey with its own pheromones, bile salts The Christian Science Monitor (10/11) The silver lamprey, a cousin to the sea lamprey but a native to the Great Lakes, doesn't shares the sea lamprey's predilection for bile salts. Thatís a find that could help researchers develop traps sparing the native lamprey species.
US poisons invasive Lake Michigan lamprey larvae Associated Press (6/4) Federal wildlife workers will go after one of the Great Lakesí greatest invasive pests this week when the larvae of sea lamprey are poisoned in a stream feeding Lake Michigan.
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 (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.
