Aquaculture water use is water associated with raising organisms that live in water, such as finfish and shellfish, for food, restoration, conservation, or sport. Aquaculture production occurs under controlled feeding, sanitation, and harvesting procedures primarily in ponds, flowthrough raceways, and, to a lesser extent, cages, net pens, and closed-recirculation tanks. This web page provides an overview of USGS's research about aquaculture water use. It includes publications, related research and a collection of data and tools (Introduction).
