My guess would be Asian Carp. They have been detected in the Chicago river and their DNA has been detected in Lake Mich I believe (doesn't necessarily mean the fish are there yet). They would absolutely devastate the local ecosystem of the Great Lakes. Once a breeding population gets into Lake Mich that's it. Game over. They have no natural predators and would repopulate without impediment, eating all of the natural fish and food supply along the way as they make their way through the entire great lakes system. Fishing is a multi billion dollar industry on the lakes and employs many. Other industries like tourism would be affected as well. chicago.suntimes.com

There are dozens from gobbi-sized on up, but the one that would be physically and economically a disaster for the Great Lakes, starting with Lake Mich. would be the Asian carp... firstly, there is not enough food in the great lakes to feed an expanding Asian carp population as well as salmon, trout, etc. -- even very large sturgeon are making a comeback -- I remember as a kid watching the commercial fishing boats come to the local harbor and offload sturgeon as big as a Humvee. Physically, the Asian carp can get quite big -- larger than a cat or small dog at least -- and they have this habit of jumping out of the water 6-8 feet. If you are on a power boat going 30-50 knots and an Asian carp jumps out of the water just ahead of you, it can take your head off -- people actually have died from injuries sustained by jumping Asian carp. The scary thing is that even carp native to Lake Mich. will simply grow and grow and keep growing as long as there's more food, etc. -- the old saying (and it's mostly true) is that carp in general are just gold fish that keep growing in size relative to how big a body of water they're in and its food supply... nobody knows how big these things might get if they make it to Lake Michigan. Right now, today, the only reason there are no sustainable populations of Asian carp in the Chicago area of Lake Mich., is that they've reversed the flow of the Chicago river back towards the MS River -- it used to empty into Lake Mich., which is much of Chicago's source of drinking water. And secondly, they have "electric fences" in the last few miles of the river closest to Lake Mich. that are triggered by underwater sensors and when they sense something the size, shape, etc. of an Asian carp, it triggers a high voltage shock across the entire river at several locations -- and I've seen videos of when that happens and suddenly hundreds, or thousand of these Asian carp leap out of the water, die and fall back down. This video gives you an idea: youtube.com it shows video of the carp jumping by the hundreds, and all of the various things they are doing to keep them out of Lake Mich. The entire video shows everything I've posted and some nice maps and diagrams along with actual operations on the river getting to Lake Mich... it's a long, but fascinating video story, well worth watching all the way through.
