COMMENTARY: Quagga mussels impact Lake Michigan salmon The Daily Reporter (6/15) Where did the invasive quagga mussels originate? It probably came from the discharge of ballast water from ocean ships. And now, it's part of the Great Lakes ecosystem. It's a new problem that impacts every aspect of the lake food chain.
Invaders of the Great Lakes... Sea Lamprey WBFO - Buffalo, NY (6/1) Like a vampire, the sea lamprey latches onto its prey and sucks the blood and nutrients out of fish in all of the Great Lakes. Krebill, a biological science technician with the U.S. Fish and Wildlife Service, is a part of a team whose job it is to control the invasive 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.
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.
