An Asian carp leaps into the air after being spooked by Captain Nathan Wallick of Peoria Carp Hunters so his customers can try to shoot the flying fish with bows and arrows on the Illinois River in Peoria, Illinois on June 19, 2012. Asian silver carp jump as high as 10 feet in the air when spooked by a boat motor or other disturbances in the water. The fast-breeding and voracious fish -- often called aquatic vacuum cleaners -- have wiped out native species and put a major dent in recreational fishing and boating on lakes and rivers across the central United States.

TRAVERSE CITY, Mich. β€” Officials say an Asian carp found in a Chicago waterway this summer apparently got past an electric barrier system intended to prevent the invasive fish from reaching the Great Lakes.

The Asian Carp Regional Coordinating Committee says an autopsy shows the 4-year-old male silver carp originated in the Illinois/Middle Mississippi watershed.

It was caught June 22 in Chicago’s Little Calumet River, about 9 miles from Lake Michigan.

That would suggest the carp somehow evaded three electric barriers 37 miles from the lake. But officials say they’re now sure how it happened.

Environmentalists and officials in some Great Lakes states say the barriers aren’t enough to stop the carp.

The U.S. Army Corps of Engineers recently released a list of options for strengthening defenses at a lock and dam in Illinois.
