Aquaponics is the symbiotic production of vegetables and fish. Fish eat food and release
metabolites into the water derived from the food. These metabolites are further metabolized by
bacteria, and the products of this metabolism are pumped into a plant grow bed where they are
taken up by plants for nourishment. Aquaponics is suitable for environments with limited land
and water because it produces about three to six times the vegetables (Resh 2004) and uses about
1% of the freshwater used by traditional aquaculture (Rakocy 1989).
