Wisconsin joins other states in Asian carp battle

December 30, 2009 (CHICAGO) Wisconsin's attorney general filed a brief with the U.S. Supreme Court today supporting Michigan's request to close the locks on the Chicago Sanitary and Ship Canal to keep the carp from entering the lakes.

Ohio has also filed a supportive brief.

Scientists think the fish could destroy the ecological balance of the Great Lakes if it gets into the waters.

Wisconsin officials say the carp would have serious adverse effects on Lake Michigan.

The Supreme Court is expected to consider the injunction January 8th.
