These are going to kill sportfishing in Lake Michigan.
—”These are going to kill sportfishing in Lake Michigan.”
We, taxpayers, have spent millions and millions on the “electric fence” for fish...“We may be incompetent, but at least we are slow.”

Maybe not. The Asian Carp need long rivers with good current to breed / for their eggs to properly develop and hatch. And said river would have to flow that distance downstream into Lake Michigan.
So... For all intents and purposes, large scale migration in from the Chicago River is already blocked. I took a look at Lake Michigan's major sources, and only the Kalamazoo River looks like a potential problem / breeding ground. So, electric fence it, put in a reservoir along it's length (fish ladders for the trout are ok - what we want is a length of placid water to kill the carp eggs), figure out a way to harvest carp going upstream to breed... Etc. Possibly an electric fish fence would be needed at the Mackinaw Straits. The mitigation does not have to be totally effective, because the carp can't breed in the main lake or smaller tributaries. A few carp are not going to hurt the lake.
