Simple Summary
Fenneropenaeus merguiensis, one of the largest penaeid shrimp species, has a wide germplasm distribution along the southeastern coast of China, although its germplasm characteristics remain inadequately explored. This study conducted comprehensive analyses of basic nutritional components, amino acids, fatty acids, antioxidant indices, and genetic diversity across three F. merguiensis populations (FmRP, FmSZ, FmSY). The findings revealed that FmSZ had significantly higher ash, crude protein, and essential amino acid levels, indicating superior nutritional quality. FmSY showed a potential nutritional advantage due to its fatty acid profile. All populations demonstrated high levels of polyunsaturated fatty acids (DHA, EPA), along with strong antioxidant capacities. Genetic analysis showed FmSZ had the lowest inbreeding coefficient and relatively higher genetic diversity. Overall, FmSZ stands out as a high-quality candidate for aquaculture and genetic breeding, highlighting the value of F. merguiensis as an aquatic product with considerable potential for wider promotion and development.
Abstract
Fenneropenaeus merguiensis is one of the largest species of penaeid shrimp. It has a wide distribution of germplasm resources in the South China Sea and the southeastern coastal regions of China, yet its germplasm characteristics remain insufficiently understood. Therefore, we conducted analyses of basic nutritional components, amino acids, fatty acids, antioxidant indices, and genetic diversity in three F. merguiensis populations (FmRP, FmSZ, FmSY). The results showed a significant difference in ash content, with FmSZ having the highest ash content (1.77 g/100 g) (p < 0.05). A total of 17 amino acids were detected, and FmSZ exhibited higher concentrations of most amino acids, especially essential amino acids (p < 0.05). The analysis of fatty acid composition revealed significant differences between the populations, with FmSY potentially having a nutritional advantage overall (p < 0.05). In terms of antioxidant capacity and genetic diversity, there were no significant differences in total antioxidant capacity (T-AOC), catalase (CAT), or superoxide dismutase (SOD) among the populations (p > 0.05). However, genetic analysis indicated that FmSZ had the lowest inbreeding coefficient and relatively higher genetic diversity. In conclusion, among the three F. merguiensis populations, FmSZ has relatively higher nutritional quality and genetic diversity, and F. merguiensis is a high-quality aquatic product worth promoting. The analysis and characterization of various aspects of F. merguiensis from the three locations provide important information and data support for germplasm resources and genetic breeding efforts.
