I've heard lot's of things about these non-native fish. That they were imported to help clean up sewage and other types of waste ponds for one, they were a fast growing/multiplying food fish that would produce lots of protien cheaply is another. I am also aware of the threat they pose to our native fish today and would have killed the other one if I had known that then. If the gubmnt wasnt so broke, they might be able to pay fisherman a bounty to try to eradicate them. I for one would gladly try to help stop them from damaging our native fish stocks especially if i could be payed to do it, they are not abundant here in N.C as far as I know............We should have learned a lesson w Kudzu.
