Aquaponics

"Aquaponics is an integrated aquaculture (growing fish) and hydroponic (growing soilless plants) system. First, the waste from fish tanks is pumped to a section of the system to be treated with a natural bacteria that converts the waste--which is largely ammonia--first to nitrite and then to nitrate. At that point, the fish waste is in a state that can be used to feed the plants. The fish wastewater is then pumped to a media bed or other hydroponic system to be used as nutrient solution by the growing plants." -- Chia L., 05/29/2001
