A number of large salmon farming companies are now investing significantly to increase land-based, water recirculating aquaculture systems (RAS) in northern Europe and North America, and there is likely a need for more trained farm personnel to run and manage
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.
