The U.S. Army Corps of Engineers has found new evidence that Asian carp are crossing the electric barrier that is supposed to keep the invasive fish from moving into Lake Michigan.
The ACOE website shows that eDNA evidence of bighead and silver carp was found in the Des Plaines River close to Lake Michigan during sampling conducted in October. No further details were given about the discovery.
Late last year DNA from Asian Carp was detected beyond the electric barrier in the Chicago Sanitary and Shipping Canal as well as in Lake Michigan. Officials responded to these signs of carp migration by poisoning the canal system.
Over the summer a live 20lb. bighead carp was caught in Lake Calumet, a heavily industrialized northern Indiana lake with a barrier free connection to Lake Michigan.
Asian carp can grow up to 100 pounds and eat 40 percent of their body weight each day and experts have warned that if they become established in the Great Lakes they could decimate the region’s seven billion dollar a year fishing industry.
This week the Corps released
a plan for a study on how to stop the migration of Asian carp into the Great Lakes.
Michigan, Wisconsin, Minnesota, Pennsylvania and Ohio are suing the Corps for not doing more to stop the carp.
The states have asked an Illinois federal court to make the Corps accelerate its study and take other emergency steps to protect the Lakes.
