A recent study evaluated the effects of a fishmeal-free diet on Atlantic salmon performance and fillet quality during successful growout to market-size in a commercial-scale, land-based, closed-containment system using water recirculation technology. Test fish performed well, with 97 percent survival
To evaluate the application of an air pressure-based transport method within a recirculating aquaculture system, the authors performed testing with harvest-size salmon at The Conservation Fund Freshwater Institute.
The use of larger and deeper tanks can reduce building, labor and other aquaculture production costs. However, the ability to grade and transfer large numbers of fish is more challenging when using large tanks. In a comparison of the effectiveness
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.
