I have wasted far too much time in this debate attempting to "prove" my point. I have posted many source materials that cover the gambit from climate to breeding that shows a fish removed from it's native enviroment and introduced into another enviroment that this can give the introduced fish an unfair advantage. This is my point of debate and I think I have proven my case. I will let the other "sensible" members on this board make the final judgement.
