“…The trend of decreasing egg and oil size as the spawning season progresses has been documented for other Seriola species such as S. lalandi, S. quinqueradiata, S. rivoliana, and S. dumerili (Mushiake, Kawano, Kobayashi, & Yamasaka, 1998;Quiñones-Arreola et al, 2015;Roo et al, 2014). Egg hatching rates and larval survival to first feeding for CYT vary over the season and yearly averages (n = 3) range from 60 to 62% and 64.5 to 67%, respectively (Stuart et al, 2020). Both egg hatching rates and larval survival to first feeding have been correlated with good F I G U R E 1 Relationship between water temperature and egg production from a CYT spawning group at HSWRI in 2019 quality eggs in other marine species (Aristizabal, Suarez, Vega, & Bargas, 2009;Bourque & Phelps, 2007) but this was not found to be true for CYT or red snapper, (Bourque & Phelps, 2007;Stuart et al, 2020).…”

Extensive nutrition research in CYT has demonstrated that broodstock diet plays an important role in egg and larval quality, with components such as taurine, linoleic acid, and arachidonic acid being important to successful egg and larval production (Salze, Stuart, Jirsa, Davis, & Drawbridge, 2017;Stuart et al, 2020;Stuart, Johnson, Armbruster, & Drawbridge, 2018).…”

“…Egg quality assessment and parentage analysis research have allowed us to understand that broodstock age and condition are likely correlated to egg viability and egg quality, with the oldest and largest females (>30 kg) displaying lower viability; the cause likely due to the senescence of fish nearing the end of their natural lifespan (Gruenthal, Gauger, & Drawbridge, 2014;Stuart, Armbruster, Johnson, & Drawbridge, 2020). Over the past 13 years, we have looked at egg and larval morphometrics, hatching rates, and survival to first feeding, in an attempt to determine indicators of good quality eggs.…”

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. Most notable among bottlenecks to commercialization in the United

“…lalandi ; Martinez‐Takeshita et al, 2015; Purcell et al, 2015; Baxter, 1960), is poised to become one of the first commercially developed offshore aquaculture finfish species in Southern California. Similar to other pelagic finfish, Seriola are aggregate, broadcast spawners, releasing gametes in multiple synchronized events during warmer months (Baxter, 1960; Poortenaar et al, 2001; Rodriguez‐Barreto et al, 2013; Sala et al, 2003; Stuart et al, 2020; Sumida et al, 1985). Due to this spawning behaviour, individual parental contribution in the wild or culture has been difficult to ascertain, and little is known about spawning dynamics in this or other Seriola species (Knibb et al, 2016).…”

Spawning dynamics and egg production characteristics of captive Seriola dorsalis assessed using parentage analyses

In pelagic fish species, studying reproductive behaviour and spawning dynamics is challenging. In culture scenarios, these parameters are difficult to investigate for broadcast spawners such as Seriola. Hubbs‐SeaWorld Research Institute has been culturing California yellowtail (S. dorsalis) since 2003 and now it is poised to become one of the first commercial offshore aquaculture marine finfish species in Southern California. Brood fish are typically kept in large tanks and spawn volitionally throughout the spawning season. This method is successful in yielding a consistent supply of eggs; however, it limits the understanding of spawning group dynamics or individual brood fish contribution, information that will be important to scaling production to commercial levels. In this study, genetic‐based offspring parentage analyses were used to evaluate captive spawning dynamics in S. dorsalis over two consecutive spawning seasons. The analyses determined that typically one female released eggs during a spawning event, compared with an average of six males who released milt during these same spawning events. Notably, the analyses revealed that a single female dominated spawning output in both years, participating in 63 spawning events and producing 49.7 million eggs. The largest single spawn contribution by a female was 2.5 million eggs, corresponding to a batch fecundity estimate of 110,000 eggs kg−1. The spawning interval for the most productive females was 5–6 days. Using genetic tools to characterize spawning events will help to improve breeding programme designs for S. dorsalis, and this information can serve as a proxy for estimating spawning capacities of this species in the wild.

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

California yellowtail (CYT; Seriola dorsalis) are continuous spawners and rely entirely on their diet to supply nutrients like fatty acids (FAs) to their eggs to support early development. The objective of this study was to determine if commercial diets can replace fresh fishery products (FFP‐D) without compromising egg quality and biochemical composition, specifically FAs. In 2017, one group (1 female and two males) of broodstock was fed a formulated reference feed (REF‐D; Bio‐Oregon). This pilot experiment showed that it was possible for a minimum of one female and two male broodstock to spawn repeatedly in a tank which led to a replicated diet experiment in 2018 where 18 yellowtail broodstock were divided into six replicates tanks, with 1 female and 2 males per tank. Three tanks were fed a FFP‐D control and three tanks were fed a commercial diet (COM‐D; Breed‐M, INVE). For each spawn event, egg quality metrics were collected along with samples for FA analysis. The 2017 REF‐D treatment produced eggs that met arachidonic acid (ARA) and eicosapentaenoic acid (EPA) requirements and had comparable egg metric parameters as FFP‐D with higher viability and average batch fecundity. However, it had insufficient docosahexaenoic acid (DHA) and no tank replicates. The 2018 COM‐D treatment produced eggs with large egg and oil diameters and met ARA and EPA requirements but had very poor spawn and hatch success with insufficient DHA levels. The FFP‐D treatment produced below average viability and batch fecundity rates and was unable to meet most EFA requirements, but it yielded the greatest number of spawns events. None of the experimental treatments including the control were able to fully meet nutritional requirements of CYT broodstock. These results reveal crucial data about current CYT broodstock diets that would facilitate future research of developing nutritionally complete diets especially in terms of EFAs.
