The lawsuit, filed Monday, follows the discovery in early December of a single Asian carp about six miles from the Lake Michigan’s Chicago coast. The fish, a bottom feeder, is presumed to have entered the Chicago Sanitary and Ship Canal, which links Lake Michigan to a tributary of the Mississippi River. The species has gradually migrated northward from Mississippi and Arkansas, where the fish were introduced in the 1970s to help clean catfish farms.
The discovery of the one Asian carp by the US Army Corps of Engineers, the Metropolitan Water Reclamation District of Greater Chicago, and the Illinois Department of Natural Resources raised alarms in neighboring states because the fish has never before been found this far north. Neighboring states say the huge carp, if they reach Lake Michigan, will destroy the ecosystem of the Great Lakes and, along with it, the lakes' $7 billion fishing and tourism industries.
