CHICAGO - The dreaded Northern Snakehead, a voracious predator dubbed the "Frankenfish" that can breathe out of water and wriggle across land, has invaded the Great Lakes, authorities said. Scientists with the Illinois Department of Natural Resources identified the 18-inch-long (46-cm-long), sharp-toothed fish netted over the weekend in a harbor near Chicago's downtown by a fisherman, who put it in his freezer and posted a photograph of the creature on the Internet.
A native of China, the Northern Snakehead was first discovered in 2002 breeding in East Coast ponds - one of which was poisoned and another drained - and has since been spotted in the Potomac River in Virginia, in Florida and in other places - but not, until now, in the Great Lakes.
"These things are voracious feeders. They're a very aggressive fish," said Mike Conlin of the Department of Natural Resources. "We hope it's a stray, dumped there by somebody who got tired of feeding it."
Teams will use electric cables in the harbor to shock fish to the surface to look for more of the species, which can survive the cold Midwest winter and eats other fish, frogs and even birds and mammals. If it breeds, it could devour game fish and devastate the lakes' multibillion-dollar fishing industry."
