The invasive Asian Carp has been detected past the electric barrier on the Chicago Ship and Sanitary Canal, just 6 miles upstream of Lake Michigan. If the fish were to reach the Great Lakes, it would be an ecological disaster. The carp consume enormous amount of food that other fish rely on, muscling out native species. The fish can grow to up to 3 feet long and weigh 100 pounds, and have quickly dominated U.S. waterbodies where they invaded. The fish also pose a risk to people: the silver carp are easily startled and often jump out of the water when startled, making them a hazard to boaters, anglers and water-skiers.
