For years, Asian carp have been slowly moving up the Mississippi River. In addition to competing with native fish, they jump out of the water when startled—sometimes even posing a hazard to boaters.
Now, with the invasive fish nearing Chicago, the Obama Administration has announced a new strategy for preventing the carp from entering the Great Lakes, where they could threaten a sportfishing industry worth $7 billion. The plan also includes money for research on how to battle the fish. However, the move appears unlikely to end a feud between midwestern states over what to do about the carp.
