As Michigan’s top lawyer, Attorney General Mike Cox should “vigorously pursue every legal means to prevent Asian carp from entering the Great Lakes,” Gov. Jennifer Granholm and Lt. Gov. John Cherry said in a joint release today.
DNA from the invasive fish has been detected beyond an electrical barrier designed to keep them from migrating from the Chicago Sanitary and Shipping Canal into the Great Lakes.
If the carp become established in the great lakes, they are expected to destroy native fish populations by eating up all available food. The fish can grow to be four feet long and can weigh as much as 100 pounds.
“We believe that emergency action to close the Chicago Sanitary Shipping Canal locks, and ultimately, the permanent biological and/or hydrological separation of the Great Lakes from the Mississippi system via the Chicago Sanitary and Ship Canal must be fully explored and appropriate legal action pursued as quickly as possible,” Granholm and Cherry said in their public letter to Cox.
Federal and state officials in Illinois plan to dump poison into a section of the Chicago Sanitary and Shipping Canal this evening in an effort to kill the carp before they reach the Great Lakes.
