What's New Stockbridge HS invention to monitor Great Lakes pest Lansing State Journal (5/27) In Michigan, a team of Stockbridge High School students has spent the past year designing an underwater camera to keep tabs on the state’s fight against invasive sea lampreys. Next week their invention will get its first real test.
Sea lamprey control planned for Chippewa, Pine rivers Midland Daily News (5/12) U.S. Fish and Wildlife Service personnel will apply lampricides to the Chippewa and Pine River systems in Isabella and Midland counties, in Mich., to kill sea lamprey larvae burrowed in the stream bottom.
Great Lakes Science Waves (4/26) The latest edition of Great Lakes Science Waves, the newsletter of the U.S. Geological Survey - Great Lakes Science Center, is now available online. Topics include the Great Lakes Fishery Research Authorization Act of 2016, pheromone technology for sea lamprey control, and more.
Eel-ladder style traps: A new lamprey control tool (3/21) Under the Great Lakes Fishery Commission's sea lamprey control program, traditional funnel traps have been used for decades as a lamprey control method. With the recent development of new lamprey trapping technology, there is now a new tool to aid in lamprey control while protecting desirable fish.
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.
