P. Bass starts dying below 60 degrees.
The P. Bass in Florida are non-native fish brought in by the State from S. America to control the exploding population of non-native cichlids that have proliferated in its waterways from accidental release from fish farms during floods and not so accidental release by aquarium hobbyists.
The P. Bass was designated as a SportsFish by the State to help them get established. This part of strategy worked so much it has taken over some lakes...It's a matter of time before they take over the Everglades....Could be good for some not so good for others....
That's what my research indicates. Google Florida Peacock Bass and you may dig up more about it.
