Recirculating aquaculture systems (RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. [1] Other types of filtration and environmental control are often also necessary to maintain clean water and provide a suitable habitat for fish. [ 2 ]

RAS requires specialized equipment and technologies designed to provide the fish with optimal water quality and control. A diagram and simple breakdown of these components can be explored by visiting the Recirculating Aquaculture Salmon-Network (RAS-N) website.
