Aquaponics is the use of both aquaculture (the practice of growing fish in tanks) and hydroponics (the practice of growing plants in a soilless environment) in order to create a cooperative living environment. The basic principle is that fish are raised in tanks, and part or all of the nutrient-rich wastewater is then circulated to the hydroponic plant production system. The plants take up the water and nutrients, thereby cleaning the water, which is then circulated back into the fish tanks.
