Interpretive Summary:

Technical Abstract: The benefits realized by recirculating aquaculture systems (RAS) - including enhanced fish growth, product quality and survival, as well as reduced treatment costs - have made the RAS approach an important production trend. Existing operations are demonstrating that land-based closed containment technology is adequate for the production of salmon and other food fish. RAS production is scaling up to achieve economies of scale. In addition, locally produced, RAS-grown fish offer many advantages that can be used to market the product. Improvements to optimize fish production, mitigate off-flavors, reduce discharges, cut costs and further enhance biosecurity are also featured in this review article. The article also highlights results from recent trials producing food size (4 to 6 kg) Atlantic salmon in RAS.
