Abstract 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.

The demand to produce larger Muskellunge to meet stocking purposes and objectives has required hatchery facilities to hold these fish through multiple life stages. Rearing of advanced Muskellunge fingerlings at the North Platte Hatchery required insertion of a passive integrated transponder tag (PIT), which also created an opportunity to track the growth and survival of these fish that were held overwinter in an extensive culture pond. This study PIT tagged 806 fingerling Muskellunge in October 2021 that were placed in a 0.1‐ha earthen pond. In March 2022 the pond was drained, and individual survival and growth were recorded. The observed overwinter survival (91.9%) was satisfactory to meet most production goals, but observed growth was minimal (21.7 ± 0.2 mm). The fall mean length of surviving Muskellunge (267.8 ± 0.9 mm) was significantly greater (t = 5.12; p ≤ 0.001) than the fall mean length of overwinter mortalities (251.4 ± 3.1 mm). Differential growth was observed with smaller individuals exhibiting greater growth during the winter, which dampens length variability within the stocked cohort. Future use of extensive culture ponds for advanced age‐1 Muskellunge production should consider the lengths desired by managers along with the associated costs of alternative production methods. This study provides expectations of overwinter survival and growth for these hatchery products.

The Texas Parks and Wildlife Department's (TPWD) Marine Stock Enhancement Program has introduced an average of 20 million fingerling Red Drum Sciaenops ocellatus into bays across Texas annually since 1983. Red Drum fingerlings are released during seasons outside of wild juvenile Red Drum recruitment, exposing them to conditions that they would not normally encounter as early stage juveniles in the wild. Furthermore, releases encompass a wide range of sizes outside of the target release size of 35 mm (20–60 mm), implying that survival and growth in the wild may vary with body size and body condition upon release. This study determined the impacts of season and initial release size on overall growth rate, body condition, and survival of Red Drum fingerlings by exposing two discrete size‐classes to a laboratory simulation of conditions expected to be encountered in the wild for 1 month after harvest from grow‐out ponds. Fish with an initial size of 35 mm TL or greater had higher overall survival over all three seasons of release than smaller fingerlings; however, final body condition (Fulton's K) was not significant across size‐classes. Growth rates of both size‐classes were highest in summer, indicating that elevated temperatures can benefit fish within the full range of release sizes. Fitted multiple linear regression modeling also determined that water temperature and size‐class were significant indicators of estimated growth rate. In addition, growth rates in wild fish as estimated from TPWD fisheries‐independent samples were consistently lower than those in experimental fish of both size‐classes during all three simulated seasons. This research suggests that releasing larger‐sized (>35‐mm TL) Red Drum may significantly improve survival, especially during seasons with more variable temperature conditions at the beginning and end of the TPWD hatchery release season.
自1983年以来，德克萨斯州公园和野生动物部(TPWD)的海洋种群增强计划平均每年向德克萨斯州的海湾引入2000万只红鼓鱼鱼苗。在野生红鼓幼鱼招募季节之外，红鼓幼鱼被放生，使它们暴露在它们通常不会遇到的条件下，作为早期的野生幼鱼。此外，在35毫米(20-60毫米)的目标释放尺寸之外，释放的尺寸范围很广，这意味着在野外的生存和生长可能会随着释放时的体型和身体状况而变化。本研究确定了季节和初始释放大小对红鼓鱼鱼种的整体生长速度、身体状况和存活率的影响，方法是将两种不同大小的鱼种暴露在实验室模拟中，模拟从生长池收获后1个月的野外环境。初始尺寸为35 mm TL或更大的鱼在所有三个季节的总存活率都高于较小的鱼种;然而，最终身体状况(Fulton’s K)在不同的体型类别中并不显著。这两种鱼种的增长率在夏季都是最高的，这表明温度升高对所有放生鱼种都有好处。拟合的多元线性回归模型也确定水温和大小类别是估计增长率的重要指标。此外，在所有三个模拟季节中，从TPWD渔业独立样本中估计的野生鱼类的生长率始终低于两种大小类别的实验鱼类。本研究表明，放生较大尺寸(> - 35 mm TL)的红鼓鱼可以显著提高成活率，特别是在TPWD孵化场放生季节开始和结束时温度变化较大的季节。
