Commercial aquaculture operations for sablefish currently use fish obtained from the wild as a source of gametes for fingerling production. Sourcing broodfish from the wild results in a small segment of the natural genetic variation present as well as a continually changing genetic background from year to year. Domesticated broodstocks have a known genetic background, perform better in captivity and can be used for the selection of traits of interest such as fast growth. F1 sablefish broodstock families have been generated at the NWFSC's Manchester Research Station from single pair crosses and are being reared to sexual maturity. The genetics, growth, and reproductive performance of these fish are being continually assessed.
