Poison Fails to Reel in Asian Carp

Poison operation kills 100,000 pounds of fish

For the second time, a poisoning operation aimed at eradicating the dreaded Asian carp from Chicago's waterways has turned up nary a carp.

Officials laced a 2.5-mile stretch of the Little Calumet River with Rotenone Thursday in an effort to kill the Asian carp. They dropped the poison in a spot experts detected Asian carp DNA in the past. 

To be sure, the poison worked -- on just about everything else.

It killed more than 100,000 pounds fish, but of the 40 species killed, none was of the bighead or silver carp family. Scientists fear those two species of Asian varieties could slip into the Great Lakes and devastate the fishing industry.

John Rogner of the Illinois Department of Natural Resources says if Asian carp are in the area, there aren’t very many.
