CHICAGO, Feb. 18 (UPI) — Fishing crews said they found no Asian carp in the Chicago canal system during the first day of an expedition focused on the spread of the invasive species.
The Milwaukee Journal-Sentinel said Wednesday the first day of the two-week expedition yielded no Asian carp, which are seen as a threat to the ecosystem of Lake Michigan.
The expedition comes months after DNA tests indicated the invasive species bypassed an electric barrier intended to stop the fish from using the canal system to reach Lake Michigan.
Despite the results of last November’s tests, as well as other tests indicating Asian carp may have reached Lake Michigan, not a single member of the species has been located beyond the $9 million barrier.
If Asian carp are able to use the canal system to move from the Mississippi River to Lake Michigan, experts are concerned the species’ voracious hunger could threaten the Great Lakes fishery.
The Journal-Sentinel said the federal government is currently eying a plan to install new barriers in the Chicago Sanitary and Ship Canal to stop the spread of the species.
