Live Asian carp found just 9 miles away from Lake Michigan

A 28-inch, 8-pound live Asian carp was found in a Chicago waterway.

The carp was about nine miles away from Lake Michigan, and officials say it made it past an electric barrier system that is used to keep the fish from getting into the Great Lakes.

On Thursday, a commercial fisherman caught the fish below a lock in the Calumet River on Chicago's south side.

Officials told the Chicago Tribune it's likely the carp was a loner that made its way to the unusual area.

The carcass of the fish has been sent to Southern Illinois University where biologists will try and see where it came from.
