A coalition of federal and state agencies will come together tonight to poison the Chicago Sanitary and Ship Canal in the hope of killing off any Asian carp that may have breached the electrical barrier and moved within a few miles of reaching Lake Michigan. The Detroit News reports:
Officials from the Environmental Protection Agency, U.S. Fish and Wildlife Service, U.S. Coast Guard and the Illinois Department of Natural Resources will use the toxin rotenone to kill whatever carp may be in a several-mile stretch north from the barrier.
Rotenone disrupts the fish’s ability to metabolize oxygen, leading to death.
Prior to the application, wildlife officials will attempt to remove native fish from that stretch by shocking them, capturing and relocating them.
Starting tomorrow, barges with cranes on them will start scooping up the dead fish — estimated to be as much as 250,000 pounds — from the canal.
