What is aquaponics? Basically, it is a symbiotic merger of aquaculture (raising fish and other aquatic animals in tanks) and hydroponics (growing plants in water). It is an extremely sustainable system because the fish waste (nutrients) is not dumped into the environment but rather happily used by the plants, which serve as filters so that clean, oxygenated water can be recirculated back to the fish. Fluid Farms has become a regional model of aquaponics and source of information for others interested in developing such systems.
