    Came out out of a 1/10th acre pond.

    Back when I studied fisheries decades ago it was thought a fish was limited by the size of the container it was in. It turns out it was not the size of the container, but the ammonia, nitrites, and nitrates that increased with the size of the fish or pounds of fish per water unit i.e. gallons liters etc. If one can keep those levels nil to none with bacterial and mechanical filtration the container itself is not the limiting factor.

    One can rear up to 2 pounds of tilapia per gallon of water with a good bacterial and filtration system which includes ozone. That's like having 20 pounds of fish in a. 10 gallon aquarium.

    I've reared 75 lbs. of yellow perch in a 150 gallon DIY. recirculating tank.

    At this point in time but who knows in the future? It would have to be something that removes the oxygen molecule from the water at precipitous rate. So yes I agree lots of energy required and possibly of massive size.
