The status of <scp>California</scp> yellowtail <scp> <i>Seriola dorsalis</i> </scp> as a commercially ready species for marine U.S. aquaculture

California yellowtail (CYT; Seriola dorsalis) is a promising candidate for marine aquaculture in the United States because there an existing market and cultured spp. command prices as high $27.70 per kg head-on gutted product. Methods commercial-scale fingerling production growout have been refined globally recent years. Spawning can be accomplished without hormone therapy adults spawn viable eggs when ambient water temperatures are between 15 22°C. Larval culture of CYT includes rotifers Artemia, with addition greenwater. survival to 1 g juveniles (45 days post hatch) typically at 30–60%. However, poor swim bladder inflation skeletal malformations require culling reduce this yield substantially. Growout size Hubbs-SeaWorld Research Institute (HSWRI) has completed on very limited basis flow through tanks where it takes 18–24 months achieve weight 3.5–4.0 kg. While species commercially ready from technical business perspective, research still needed improve inflation, deformities, optimize nutrition across all life stages, assist disease diagnosis control. Most notable among bottlenecks commercialization need capacity both net pen land-based culture.
