Anyone ever use a hand dug well to raise edible fish or seafood?

6' diameter- 25' deep. 3000 gallons? +\- depending on rainfall?

Ideas / options?

Temps should stay 55 degrees even in dead of winter, right? It would be covered so no wind.

Catfish on bottom? Mesh on walls for fresh water prawn/ snails (harvest seasonally) etc, blue gill and trout can take low temps. Blue gill is coldest ive found down to 40! Turtles, frogs, snakes?

Winter survival is one thing but will it stay too cold for fish to spawn and grow properly? Maybe its only good as a holding tank...?

Obviously we would need aeration, and circulation/ clean out pump

Thx all!
