1. A fiberglass aquaculture tanks, most aquaculturalists will tell you that a round type of this tank is best if you have the space. That said, we know plenty of aquaponic gardeners growing in rectangular and square tanks that do just fine. Just make sure any fiberglass hatchery tank you consider does NOT have hollow pockets in the bottom or any other place where solid waste can accumulate.
2. In general, bigger fiberglass aquaculture tanks tend to be more stable, and it is best to shoot for at least 90- 100 gallons if you are growing edible fish to plate size.
3. You should stock your frp fish farming tank at our recommended “Rule of Thumb” of 1 pound of fish for every 5 – 10 gallons of water. An “average” amount of fish consumed per year according to the FAO is 37 pounds. A 200 gallon tank will produce about that each year.
4. You will want to have at least a 1:1 ratio of 12″ deep grow bed volume to fish tank volume. Much less than this will not provide adequate filtration for your fish. You can go all the way to a 3:1 grow bed : fish tank volume, but be sure to add a sump tank or two at that point so the water level in your fiberglass fish tank does not go too low during the flood cycle.
