Dave I am not trying to minimize anything and don't worry about offending me.
This isn't a personal issue-in-all.

All those fish you are talking about represent very small populations in very
small areas. This is the kind of exaggeration I am talking about. A breeding
population in one canal doesn't make for a state wide invasion. As long as we
accept exaggerated blame we are doing no one any good. the really damaging
introduction in Florida has been the North American Flathead Catfish (their words
not mine). Most tropical breeding populations have been highly localized and
not significantly damaging. Even the notorious walking catfish didn't have
much of an impact. I am not trying to say exotic release isn't a bad thing I am
just saying the aquarium hobby is getting far too much blame for far too little

Florida official have backed off the disaster status for most of the releases
and the numbers you quote are misleading. if you have two dozen exotics in
one canal and no where else it looks bad when you figure just numbers of species
but it's like a drop of water in the ocean when you figure actual real-estate
colonized and actual numbers of fish. native fish occur all over the state,
the exotics occur in very limited areas. Not match-in-all on a one on one
comparison of species.

This is very bad and I don't want to down grade the effect in this river but

I agree but we should also make sure that regulations are based on reality
and not someone's perceptions of what is happening. Regulations that make
sense in South Florida have no meaning in South Eastern, NC. Any regulations
should be written with the reality of the area and the real possibility of
establishment of a specific fish. Blanket regulations would be detrimental to both the
aquarium hobby and the believability of the rules themselves. Banning
electric catfish in NC would be unnecessary, in South Florida it would be necessary.
