Not just for "sport," IIRC there are some invasive species in the Mississippi River that got there when one of the floods engulfed some fish farms/hatcheries that had some exotic fish there to help maintain pests/algae/etc.

Also, Florida has a lot of iguanas (which are non-native), especially in the Everglades, you just don't hear much about it because the pythons are a larger issue.
