Update December 3rd 5:13 pm:

Marc Gaden of the Great Lakes Fishery Commission says "as far as I know, no one thinks there are any Asian Carp in Lake Erie." He says Lake Erie is colored red in the USGS map above because two Bighead carp were found in commercial fishman's nets several years ago. They colored the entire Lake red based on these two incidents.

The state of Michigan has suffered another legal setback in its effort to keep Asian Carp from reaching the Great Lakes.  

A federal judge in Chicago has denied a request by Michigan and several other states to order the closure of canals which link Lake Michigan to the Mississippi River basin. Asian Carp are a voracious invasive species.  The carp have devastated Mississippi River fish populations.  

“The court agreed that Asian Carp are indeed a threat," says Joy Yearout,  a spokeswoman for Michigan Attorney General Mike Cox, '"But the judge also ruled the actions the federal government has taken over the last several months prove they are addressing the threat enough to make it not immediate enough to require a court order."

Federal agencies have stepped up construction of electric barriers to keep Asian Carp from passing into Lake Michigan.  Other methods are also being studied. 

The states may continue their legal fight.  They are also asking President Obama to order the canals closed.

The Associated Press reports that The Charles Stewart Mott Foundation is giving $500,000 to the Great Lakes Commission to help it find ways to stop the invasive Asian carp from entering the Great Lakes.

The fish started make their way up the Mississippi River system more than ten years ago after they escaped from fish farm ponds in the south. They were imported to control parasites in the ponds.
