This chapter provides a full description of the concept of aquaponics, a technique for combining hydroponics and aquaculture in a system that cultivates plants in recirculated aquaculture water (Figures 1.1 and 1.2). It provides brief accounts of the development and nature of soil- less culture and general aquaculture. Aquaponics is then described, noting how these techniques are united, including additional considerations and a brief history of its development. An account of the major strengths and weaknesses of aquaponic food production is provided, as well as the places and contexts where aquaponics is most, and least, appropriate. Finally, there is a short description of the major applications of aquaponics seen today.
