I do want to amend my "never put anything into a natural system, period." thought with, "unless it is part of a well-researched restoration project".
NEVER release an aquarium fish into the wild.

Welcome to MFK by the way, we try and do it the right way.
Red-tailed catfish will fit this one well.johno27;239864; said:Don't forget you can always eat the fish too
A lot of those have been sold in lfs and should never have been sold to domestic aquarists. Best to leave them in their native habitat.
I completely agree with everything about not releasing fish in the wild.
Very true.
Just for the record, golden apple snails and plecos weren't even native species of the Philippines. They were introduced here either intentionally or accidentally. So far, the pleco invasion has done far more damage.
Remember, it is also best to spay or neuter your politicians and never release them into the wild.
Now stillwater angling lakes in the UK are being stocked with ornamental sturgeon.
this was an extract of impacts, including of course, thinking of banning or restricting imports.
The effects of introducing non-native fishes may cause unpredictable and irreversible ecological damage, but the long lifespans of sturgeons mean that it may be some time before the true impact of introductions is apparent, say the authors.
"As yet, there is no evidence of their natural dispersal or naturalisation, implying species have yet to become invasive.
"Furthermore, as their presence is predominantly restricted to lakes, any adverse ecological impacts may be contained therein. Nevertheless, a number of these fisheries are located in floodplains or have connections to a river, providing potential for fluvial dispersal, for example during flood events.
"Should this occur, the risks to native fish fauna may include the adverse impacts of increased competition for resources, increased depredation on eggs and juvenile fish, and the transfer of novel parasites. This is because their natural diet consists of zooplankton, fish eggs, larvae and benthic invertebrates, and they host non-native parasites, including the nematode Cystoopsis acipenseris."
Britton and Davies believe that the sale of sturgeons must be restricted to prevent further introductions.
"Their sale could be restricted to individuals with an existing licence to keep them legally. This would, however, require very careful consideration, because when this restraint was imposed on the sale of pumpkinseed Lepomis gibbosus L. in England and Wales, ornamental trade in the species virtually ceased."

I can't imagine sturgeon causing much harm, but who can say? And stocking is to be determined by "qualified" individuals, not Wurms, or fishkeepers in general. Let the government screw it up, and fishkeepers remain blameless.
