Aquaponics is the integration of recirculating aquaculture and hydroponics in one production system. In aquaponics, the aquaculture effluent is diverted through plant beds and not released to the environment, while at the same time the nutrients for the plants are supplied from a sustainable, cost-effective and nonchemical source. This integration removes some of the unsustainable factors of running aquaculture and hydroponic systems independently. The technology presented in this document provides a description of the concept of aquaponics and an overview of the three most common methods of aquaponics being utilized at present. In addition, the factors to consider when selecting a site for an aquaponic unit and the components essential for any method of aquaponics are described in detail in this document.
