What is Aquaponics?

Aquaponics combines aquaculture (raising fish in contained environment) and hydroponics (growing in a soilless, recirulating water system).  Using gravity, water is drained from the fish tank into a media bed.  Here, beneficial bacteria break down the toxic ammonia in fish waste to Nitrite and then to Nitrogen, a key nutrient for plant development.  This now filtered water is pumped to the grow troughs, where a variety of crops from specialty salad greens to tomatoes are grown.  The water is wicked up to the crops roots with the help of coir, a by-product of coconut shells and a sustainable replacement for peat moss, since no soil is used. Finally, the water flows from the growing beds back into the tank of fish. In an aquaponic system, crops are noted to grow 2-3 times faster than traditional soil environments.

When using aquaponics in a controlled greenhouse environment, fish and organic produce can be grown year-round to provide a healthy food source to anyone, anywhere.

As a sustainable agriculture, aquaponics can grow fish and produce using less than 2 % of the water, and 70-90% less energy than traditional farming, while producing eight times the vegetables in the same area in less time.
