Not without aeration and some serious management efforts.
Assuming you mean managing the forage base so they have planty to eat, this has been my focus and major concern.
Aeration...
Are you concerned might have a kill or just lower oxygen in a small warm pond might limit growth potential?
other thought I had was winter temps, even if the temps dont get below leathal temps I think they get colder than they would stay in during the natural range and slow or stop them from feeding for about 2 months, Jan - Feb, that could limit or slow growth some too.......?
