The status of California yellowtail Seriola dorsalis as a commercially ready species for marine U.S. aquaculture

Abstract

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

Characterization of supply of marine finfish species with potential for commercial growth in the United States

“…Rexroad et al (2021) summarized the results of a series of workshops held to identify marine finfish species with potential for commercial farmed production in the United States. These include: almaco jack, Seriola rivoliana , Atlantic cod, Gadus morhua (Nardi et al, 2021), black drum, Pogonias cromis , black sea bass, Centropristis striata (Watanabe et al, 2021), California flounder, Paralichthys californicus (Stuart et al, 2021), California yellowtail, Seriola lalandi ( formerly S. dorsalis ) (Rotman et al, 2021), cobia, Rachycentron canadum (Benetti et al, 2021), Florida pompano, Trachinotus carolinus (Weirich et al, 2021), greater amberjack, Seriola dumerili , olive flounder, Paralichthys olivaceus (Stieglitz et al, 2021), red drum, Sciaenops ocellatus , red snapper, Lutjanus campechanus , sablefish, Anoplopoma fimbria (Goetz et al, 2021), southern flounder, Paralichthys lethostigma , spotted seatrout, Cynoscion nebulosus (Blaylock et al, 2021), spotted wolffish, Anarhichas minor , striped bass, Morone saxatilis (Andersen et al, 2021), summer flounder, Paralichthys dentatus , tripletail, Lobotes surinamensis (Saillant et al, 2021), and white seabass, Atractoscion nobilis (Drawbridge et al, 2021).…”

Current status of carangid aquaculture and way forward

“…(2.3) Induced spawning technology: Some carangid species reach gonadal maturation and spontaneously spawn in captivity, such as blue trevally (Moriwake et al, 2001), California yellowtail (reviewed by Rotman et al, 2021), greater amberjack (Kawabe et al, 1996(Kawabe et al, , 1998, yellowtail amberjack (Moran et al, 2007;Setiawan et al, 2016) and white trevally (Nogueira et al, 2018). However, in most cases, hormonal administration is required by either injection of hCG or injection/implantation of luteinizing hormone releasing hormone analogue (LHRHa), as detailed in Table 3.…”

Influence of broodstock nutrition on egg quality and fatty acid composition in California Yellowtail

“…2020; Rotman et al. 2021). In 2021, the commercial landings of CYT in California amounted to 17.6 metric tons and had an exvessel value of US$111,690 (California Department of Fish and Wildlife 2022).…”

“…The California Yellowtail (CYT) Seriola dorsalis, also formerly known as the Yellowtail Kingfish Seriola lalandi, is a carangid fish found in the temperate waters of southern California, with recreational, commercial, and potential global culture value (Martinez-Takeshita et al 2015;Ben-Aderet et al 2020;Rotman et al 2021). In 2021, the commercial landings of CYT in California amounted to 17.6 metric tons and had an exvessel value of US$111,690 (California Department of Fish and Wildlife 2022).…”

“…Since 2003, research into the development of culture methods for CYT in the United States has been largely accomplished by Hubbs-SeaWorld Research Institute (HSWRI; Rotman et al 2021). For every cultured species, the reliable production of juveniles is dependent on high-quality eggs, which are especially influenced by nutrients obtained from the broodstock diet (Bromage and Roberts 1995;Brown et al 2006;Migaud et al 2013;Biswajit et al 2020;El-Gamal et al 2020).…”
