well in the summer the temps reach 100+, while at winter it gets well below freezing.Define "cold". If you can maintain water temps under 65 you can probably keep Brown Trout, which imo will taste better than any of the previously mentioned species. Otherwise I would say Yellow Perch.
first, id like to keep the fish in the pond year round, and a stable population n whatnot. also, i think tilpia are out because of the the cold winters correct? someone please correct me if im wrong, but from a quick google search they say 70f for tilpia.Tilapia are generally considered the most efficient food fish as far as turning food mass into body mass in a short period of time....start with some small ones in the spring, power feed them all summer, and have a fall fish fry..
you my dear think to much like a tank person. this will be an actual pond.one issue i think would be the dechlorinator used in the pond. .
correct, the summer months get really hot. i personally would like tilpia, but i think thats out, so 2nd option i was thinking of was native blue gill and large mouth bassOhio is not always a "cold water" state. I live in PA (similar climate) and last summer when we were camping, there were scores of dead carp in the river we camp near. The water was like bath water - and that's a flowing system that theoretically should have more O2. I can only imagine how O2 depleted a closed system would be in those conditions (unless it was really deep).
All the Rock Bass, Smallmouth Bass and various sunfish we caught were none the worse for wear however. Maybe investigate those species (although Smallmouth and Rock Bass are usually riverine species). Largemouth Bass can manage at a wide variety of temps as well.
