HSWRI researchers were the first to successfully spawn and rear the larvae of California yellowtail from broodstock collected in the early 2000s. California yellowtail is an sportfish indigineous to southern California which is marketed as hamachi. Extensive research has documented the optimal conditions for farm raising this desirable finfish, which is usually marketed in sushi restaurants as hamachi. Farm raising of these fish will ease pressures on wild fish, reduce overfishing and provide a clean and reliable source of this healthy seafood.
HSWRI is conducting continuing research on these fish with ground breaking results. For example, a captive population of California yellowtail (Seriola lalandi) was used to document spawning patterns, including measures of egg production, population fecundity and egg and larval quality from 2007 to 2010. Spawned eggs were also used to document larval development and to develop rearing techniques for aquaculture in the region. This research represented the first documentation of successful spawning and larval rearing for S. lalandi in the eastern Pacific.
