“…A high fertilization rate and hatching rate will catalyze the industrial development of P. argenteus. However, in the first and second generations, relatively lower fertilization and hatching rates were observed in P. argenteus compared to other fish species (Aya et al, 2022;Nowosad et al, 2023). We speculated that this might be attributed to differences in the timing of spawning and milt expulsion in the P. argenteus (Fennell et al, 2023).…”

Silver pomfret (Pampus argenteus) is among the highly favored marine edible fishes in China. To determine whether sustained advancements can be realized and to assess the genetic parameters of P. argenteus across three generations. Measurements of growth traits were conducted in the control and breeding groups of third-generation P. argenteus at 60, 90, and 120 days. Utilizing Pearson correlation and path analysis, we identified the growth traits correlated with the body weight of the third-generation P. argenteus. The results indicated that the growth traits significantly correlated with body weight were body length and fork length. At 120 days, body weight, body length, and fork length exhibited high levels of realized heritability, measuring 0.55, 0.57, and 0.56, respectively. Genetic gains for body weight were 29.70%, significantly surpassing those for body length and fork length. Meanwhile, the selection response for body weight, body length, and fork length was approximately comparable. At the harvest on day 120, the breeding group was 33.93% larger than the control group in terms of body weight. These results indicated that through mass selection, the body weight of P. argenteus were successfully improved, leading to an enhancement in its growth performance. The research results provide theoretical support and technical guidance for the further development of P. argenteus breeding.

“…Consequently, temperature affects spermatozoa metabolism and energetics, which are determinants of motility kinetics. 22,57,[62][63][64] Considering species as a moderator, variations in IWT effects on MOT in warm-water species were shown. These were more negative in Nile tilapia, Waigieu seaperch and Tambaqui compared to gilthead seabream and Japanese eel.…”

Studies have demonstrated adverse effects of global warming on aquatic ecosystems from the abiotic to the biotic level. In the present work, a meta-analysis study was conducted to elucidate the effects of global warming on spermatozoa functions, which are key determinants of male fertility. We recruited 245 data records from a pool of empirical studies, which includes 20 studies spanning 20 cold- and warm-water fish species, to identify the effects of increased water temperature (IWT) on determinants of sperm fertility in fishes. Data were systematically re-processed and re-analyzed to determine the overall effects of IWT on sperm kinetics such as motility (MOT), duration of motility (DSM), curvilinear velocity (VCL), rectilinear velocity (VSL) and average path velocity (VAP), as well as on enzymatic activities for energy supply (EAES) and antioxidant enzyme activity (ANEA). The standardized mean difference was calculated for each study, with positive values indicating higher performance under IWT. Results showed that (a) the overall effect size for MOT was more negative in cold-water fishes (-1.22) than in warm-water fishes (-0.98). (b) Each 1 oC increase in the activation medium reduced MOT by 1.30% (cold-water fishes) and 3.47% (warm-water fishes). (c) The IWT negatively affected DSM, decreasing it by 10 s (cold-water species) and 5.64 s (warm-water species) per degree of IWT. (d) Spermatozoa velocity (VCL and VSL) was increased by IWT in warm-water species. In conclusion, this study shows that IWT negatively affects sperm motility kinetics, suggesting an impact of global warming on fish reproduction.
