Aquaponics

[transcend]

Aquaponics (pronounced: /ˈækwəˈpɒnɨks/ (http://en.wikipedia.org/wiki/Wikipedia:IPA_for_English)) is a sustainable food production (http://en.wikipedia.org/wiki/Agriculture) system that combines a traditional aquaculture (http://en.wikipedia.org/wiki/Aquaculture) (raising aquatic animals (http://en.wikipedia.org/wiki/Aquatic_animal) such as fish (http://en.wikipedia.org/wiki/Fish), crayfish (http://en.wikipedia.org/wiki/Crayfish) or prawns (http://en.wikipedia.org/wiki/Prawn) in tanks) with hydroponics (http://en.wikipedia.org/wiki/Hydroponics) (cultivating plants in water) in a symbiotic (http://en.wikipedia.org/wiki/Symbiosis) environment. In the aquaculture, effluents (http://en.wikipedia.org/wiki/Effluent) accumulate in the water, increasing toxicity for the fish. This water is led to a hydroponic system where the by-products (http://en.wikipedia.org/wiki/By-product) from the aquaculture are filtered out by the plants as vital nutrients, after which the cleansed water is recirculated back to the animals. The term aquaponics is a portmanteau (http://en.wikipedia.org/wiki/Portmanteau) of the terms aquaculture and hydroponic.
Aquaponic systems vary in size from small indoor or outdoor units to large commercial units, using the same technology. Aquaponics - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Aquaponics)
