There are 4 basic types of aquaculture (simple to complex):
Home Systems
Cage Systems
Flow-Through
Greenhouse Aquaponics
This photo, to the left, is like one above-ground pool—similar to a Home system.
When the only available water is from a hose, a vinyl-lined above ground pool can be located in a basement, garage, or a yard. For a couple hundred dollars up to a couple thousand, (do fish REALLY need those ladders?) a 3-foot high, 12 foot-diameter pool will hold about 2000 gallons of water. When using unfiltered water, writer Steve Van Gorder says to expect only ~ 13 lbs of fish per year. BUT!! If you remove waste, ammonia, AND you oxygenate, that figure jumps to more than 100 pounds of fish. Almost a 10-fold increase! (And, it's not very expensive, stay tuned...)
