A live Asian carp has been discovered in a Chicago waterway about nine miles from Lake Michigan. Federal and state officials tell The Associated Press a commercial fisherman netted the silver carp below the T.J. O'Brien Lock and Dam. The fish was 28 inches long and weighed about 8 pounds.
Silver carp are among four Asian carp species threatening to invade the Great Lakes, where scientists say they could compete with native species and devastate the region's $7 billion fishing industry.
This is the second time a live Asian carp has turned up beyond an electric barrier network 37 miles southwest of the city that's designed to keep the invasive fish from reaching the lakes. A bighead carp was found in Chicago's Lake Calumet in 2010.
