Interpretive Summary:

Technical Abstract: Recirculating aquaculture systems (RAS) for the production of fish in land-based facilities reuse in excess of 90% of system water volume and can be applied to fish production at different life stages and in different environmental states. RAS are generally quite different in numerous ways compared to traditional fish farming methods, and therefore require a unique approach to managing the health of production fish in these settings. This chapter discusses the functional components of RAS, with descriptions of both fresh- and seawater systems, and describes issues such as artificial lighting approaches, rotational water velocity to stimulate optimal swimming levels, specific welfare considerations for RAS-raised fish, and typical and emerging pathogens that can cause health issues in RAS.
