Ross, it would be interesting to see what they do about a 100% milfoil pond. In the absence of anything else, I would probably eat liver and onions or even ducks. Not sure but probably.
Shorty, I expect you would lose some GC to predation. However, these things seem to grow and develop "shoulders" pretty quickly. At $15 each, I'd hate to lose any.
There is a downside to them. Like real carp, they can root around and muddy the water once the easy meals stop coming.
Catching one is a memorable experience. They are extremely strong. That's an understatement.
