As an introduced and invasive species, those jumping carp have the potential of permanently disrupting the fresh-water ecosystem of the Great Lakes.

There are no longer any effective predators of them in the Great Lakes and they are voracious feeders. However, there used to be. The alligator garfish, I think it's called. A huge flat-headed fresh-water carnivore that was eradicated from the Great Lakes because it was mistakenly considered a pest and because their scales were useful for jewelry, armor, machining and if ground up, abrasives. They are dinosaur-like and can commonly grow to 400 pounds, six feet long and they do so love carp.

If reintroduced, and once an equilibrium is achieved, gars will force those carp to coexist like the popular bumper sticker emplores the rest of us to do.

Another strategery that is immediately dismissed because it makes too much sense, is to put a bounty on those damn carp until everybody remembers how nutritious and tasty they are when done up right. That's how they got here in the first place. Flooding allowed them to breach their paddocks and escape into the ecosystem via the Mississippi, I think.
