Scientists from the National Oceanic and Atmospheric Administration (NOAA) intend to find ways to make it easier and more efficient to commercially harvest sablefish (Anoplopoma fimbria) as part of the federal agency’s efforts for marine aquaculture to contribute to meet a growing demand worldwide for seafood.
Sablefish, also known as black cod or butterfish, are a long-lived species native to the northeast Pacific Ocean and highly valued in Asia for its beneficial nutrients and delicate flavour.
In this research project being developed by the NOAA, the scientists are replacing algae with clay, which is used to help sablefish larvae better find their prey. Wild fish are caught off the Washington coast and used to develop captive brood stocks, or mature fish that are used for breeding, the agency Assocaited Press reported.
At the facility, the fertilized eggs grow in silos in dark, cold rooms before being moved to other indoor tanks where they are fed a steady diet of brined shrimp and other food. Large circular tanks hold fish in different growth stages.
