Tonight on the Discovery Channel show 'Dirty Jobs', Mike Rowe will learn to wrangle the creepy and destructive invasive species, sea lampreys. Lampreys invaded the Great Lakes during the 1920's. They are eel-like creators who have toothy, suction cup mouths that attach themselves to the side of fish, saw holes through the skin and feed on the fish's insides. These invasives had nearly destroyed several species by the 1950's. Tonight, Rowe and his crew will catch, transport and sort the lampreys by gender. After which, they will be poisoned or the males sterilized and released.
