Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants.
This modified system, known as "Speraneo Systems," employed bell siphons to facilitate an ebb-and-flow irrigation cycle, popularizing what is commonly termed flood and drain aquaponics. In 2005, Joel Malcolm purchased the Speraneo’s information kit and adapted it for use in Australia.
Saltwater aquaponics (also known as marine aquaponics) is a combination of plant cultivation and fish rearing (also called aquaculture), systems with similarities to standard aquaponics, except that it uses saltwater instead of the more commonly used freshwater. In some instances, this may be diluted saltwater.
In an aquaponics system fish effectively fertilize the plants, this creates a closed looped system where very little waste is generated and inputs are minimized. Aquaponics provides the advantage of being able to harvest and sell multiple crops. Contradictory views exist on the suitability and safety of RAS effluents to sustain plant growth ...
Plants placed into nutrient-rich water channels in an NFT system A home-built NFT hydroponic system. Nutrient film technique (NFT) is a hydroponic technique where in a very shallow stream of water containing all the dissolved nutrients required for plant growth is re-circulated past the bare roots of plants in a watertight gully, also known as channels.
Extended water purification systems allow for the reuse of local water. The largest-scale pure fish farms use a system derived (admittedly much refined) from the New Alchemy Institute in the 1970s. Basically, large plastic fish tanks are placed in a greenhouse. A hydroponic bed is placed near, above or between them. When tilapia are raised in ...
Aquaculture (less commonly spelled aquiculture [1]), also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants (e.g. lotus).
A grower utilizing a DWC system has to modify the environment as to provide the proper conditions for optimal growth. Although this is true for any protected-crop production system, such as greenhouses, indoor systems, or vertical farms; utilizing DWC comes with some specific responsibilities that the grower should heed. Most notably, the ...
