Invasive Species of Asian Carp May Have Passed Barrier to Get to Lake Michigan

CHICAGO, Nov. 20 (UPI) — Asian carp may have passed through an electric barrier intended to keep the invasive species out of Lake Michigan, new findings suggest.

The U.S. Army Corps of Engineers said Friday samples taken beyond the Chicago Sanitary and Ship Canal barrier and from Lake Michigan Sept. 23 and Oct. 1 indicate Asian carp may be within 8 miles of the lake, the Detroit Free Press reported.

Previous evidence had indicated the large fish were within a mile below the $9 million barrier.

Asian carp are seen as a significant threat to the ecosystem of Lake Michigan due to the large size of the fish — up to 50 pounds — and their tremendous appetites that could threaten native fish species.

The Milwaukee Journal Sentinel said to prevent the species from reaching the Great Lakes system, Army Corps officials plan to build a second barrier and temporarily poison the canal, which connects the Mississippi River to Lake Michigan.
