What would the carrot be?

Additional species tend not to be turning up except for aquarium releases of
stuff in canals around Phoenix which typically don't make it through the
winter or just don't make it in general.  Pacu have started to turn up in one
of the lakes in the Colorado River though, who knows if they'll take off.
Most of the releases occurred early on and are related to either sport fish
releases, bait fish releases, or mosquito control.  The main expansion of non
native fishes today appears to be bait release and people putting fish in
stock tanks.  It is near impossible to detect translocations of native fish
(I'm defining translocation here as moving it within it's native range).

How is it in the fishes (especially the threatened ones--which is many
of them in AZ) benefit by allowing Joe Blow to take them and move
them around?  Many of the polititions in Arizona would probably rather be
without any native fish.
