U.S. targets invading carp with poison, nets, shocks
CHICAGO (Reuters) - Looking for Asian carp that could pose a dire threat to billion-dollar Great Lakes fisheries, U.S. authorities announced plans on Wednesday to poison, net and shock any invaders in Chicago-area rivers.
Authorities want to find out if any of the invasive Bighead and Silver Carp -- which have populated the Mississippi and Illinois Rivers -- have made it past electric barriers erected near Chicago to keep them out of the Great Lakes.
Carp DNA has been found in Lake Michigan, prompting neighboring states to file a lawsuit seeking to have locks closed. The suit seeks a permanent separation of the century-old, man-made links between the Mississippi River and Great Lakes watersheds.
