Carp may have been planted in Lake Calumet

August 5, 2010 (CHICAGO)

The bighead carp was caught in the South Side lake back in June. It was the first Asian carp to be found above an electronic barrier meant to keep the fish out of Lake Michigan.

The discovery intensified calls to close the locks on Chicago-area rivers to keep the Asian carp from the Great Lakes.

But, now scientists at Southern Illinois University in Carbondale say, tests and analysis finds the carp may have been planted by humans.
