"The fight to keep invasive Asian carp from the Great Lakes reached the nation's highest court Monday as Michigan's attorney general sued Illinois, asking for the closing of two shipping locks near Chicago in perhaps a last-ditch effort to save the region's $7 billion fishing industry.

Contending that Illinois officials have been too lax in defending Lake Michigan from Asian carp, Attorney General Mike Cox asked the U.S. Supreme Court for immediate action in closing the O'Brien Lock and Dam in the Calumet-Sag Channel and the Chicago Controlling Works in the Illinois River -- hoping to seal off the most direct route for fish entering Lake Michigan."
