Aquaponics is an environmentally friendly technique in which both fishes, as well as plants, are grown in an integrated manner. It is a cycle in which fish waste provides fertilizer for growing plants. The plants absorb those nutrients and filter the water in the fish tank. So the fish can survive in freshwater. Aquaponics is a combination of aquaculture (growing fish and other aquatic animals) and hydroponics (growing plants without soil).
