Optimizing depuration of salmon in RAS

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.

Off-flavors in salmonids raised in RAS

The presence of compounds such as geosmin and 2-methylisoborneol (MIB) in recirculating aquaculture systems (RAS) can result in earthy or musty off-flavors in salmonids raised in the systems. 


Off-flavors in aquaculture products, part 1

Off-flavors in pond and recirculating aquaculture systems have occurred through the biological production of geosmin and 2-methylisoborneol. The compounds are rapidly absorbed through the gills of fish, but depuration can require days or weeks.
