Aquaponics

Aquaponics is a combination of the concepts of hydroponics and aquaculture. It incorporates practices from both of these concepts, allowing the waste products from one system to serve as a nutrient-rich fertilizer for the other. In aquaponics, effluent (liquid waste) from fish tanks is circulated through a special irrigation system to feed plants grown in hydroponic beds. This is an excellent model for sustainable food production, and its popularity is growing on both small and large scales. Aquaponic systems can be purchased from a supplier or constructed by hand.
