TRAVERSE CITY, Mich. – Asian carp might have breached an electronic barrier designed to prevent the giant invaders from upsetting the ecosystem in the Great Lakes and jeopardizing a $7 billion sport fishery, officials said Friday.
Scientists recently collected 32 DNA samples of Asian carp between the barrier and Lake Michigan in waterways south of Chicago, although the fish have yet to be spotted in the area, said Maj. Gen. John Peabody of the U.S. Army Corps of Engineers.
