Sea Lamprey Invade the Great Lakes

By Angelica Morrison

 

(WBFO) The sharp scent of chemicals bites the air as Jason Krebill wades in a creek and pulls out two slippery, slimy, parasitic creatures. He was holding dead adult sea lampreys one in each hand. They were about two feet long, with suction-cupped mouths, lined with nearly a dozen rows of sharp teeth. Like a vampire, the sea lamprey latches onto its prey and sucks the blood and nutrients out of fish in all five 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. The U.S. Fish and Wildlife Service is contracted by the Great Lakes Fishery Commission to apply lampricide to the creeks and tributaries throughout the Great Lakes Corridor.
