Dozens of land-based, closed-containment salmonid RAS systems are coming on line. New projects are bringing new principles into the salmon industry. Industry expansion hinges upon the development of pollution-mitigating technologies to reduce nutrients in effluents.
The benefits realized by recirculating aquaculture systems – including enhanced fish growth, product quality and survival, as well as reduced treatment costs – have made the RAS approach an important production trend.
A study to evaluated operating practices and system designs that could potentially enhance depuration of off-flavors from Atlantic salmon cultured in a semi-commercial-scale freshwater recirculating aquaculture system.
Research at the Conservation Fund’s Freshwater Institute is evaluating a prototype percussive stunning system for slaughtering food-size rainbow trout.
As confirmed in a U.S. study, partial-reuse systems are effective alternatives to traditional, serial-reuse raceway systems for salmonid culture.
