Aquaponics is a eco friendly food production method which mixes a conventional aquaculture (raising aquatic animals just like fish, crayfish or prawns in tanks) along with hydroponics (growing plants in water) within a symbiotic ecosystem.

With the aquaculture, effluents amass in the water, increasing toxicity for the fish. That water is sent to a hydroponic process during which the by-products coming from the aquaculture are actually filtered by the plants as essential nutrients, and after that the cleaned water is actually recirculated to the animals.

The word aquaponics is a portmanteau of the words aquaculture and hydroponic.
Aquaponic models differ in dimension from compact interior or outdoors units to huge professional units, employing the same know-how. The systems generally consist of freshwater, however salt water solutions are possible depending on the variety of aquatic animal as well as plants.
