Eradicating a viable species that is thriving, after the environment has already adjusted to it is not just wrong, but borders on criminal. They are taking a chance on destroying an entire ecosystem because of some perceived notion of 'purity'. Here's a flash...you can't go back. Even eradicating the newer species will not necessarily restore the waters to what they were before. The ecosystem has already been irrevocably changed, forever. All you do is even more damage.

By their reasoning, then we shouldn't be allowed to fish for carp, brown trout (introduced from Europe in the 1880s), or bass and crappie (range greatly extended by stocking programs, making them a 'non-native' species throughout most of their current range). Oh, and cottontail rabbits would be also have to be eradicated, to the detriment of all the predators that have adjusted to having them for dinner. How about Nutria? Without them, hydrilla would choke off a lot of otherwise great fishing waters.

This madness needs to stop. We fund most of the so-called 'conservation' attempts in this country, and we should have a say in the matter. Write your elected officials.
