The U.S. Geologic Service has a "Nonindigenous Aquatic Species" section that tracks exactly this kind of information across the nation.For future reference, where can I find a complete and up to date list of invasive fish species in NY?
Go to NAS ... hit FISH .... then SEARCH BY STATE etc. It's well setup for easy navigation.
Whenever you run across an non-indigenous fish in a place you've not heard it's gotten to before, check with NAS, and if they don't know about it, file an online report. For example, I've reported brown hoplos three times in new drainages from which they had not been previously been known.
