Predator in Paradise

Sea lampreys kill fish by latching on with a tooth-filled, suction cup mouth, drilling a hole through the side of the fish, and feeding on the fish's blood. They invaded the Great Lakes from the Atlantic Ocean and by the 1950s, the once thriving fishery was nearly destroyed by this unyielding vampire. This is the extraordinary story of the sea lamprey's assault on the Great Lakes and how humans fought back - and won! This video tracks the story from the days when fishers watched in shock as sea lampreys ravished through the fishery, to today, as scientists use proven and cutting-edge ways to keep this noxious predator in check. The battle against this unwelcome predator in paradise continues!
