Comparative Analysis of Amino Acid Composition, Fatty Acid Profiles, and Genetic Diversity Among Three Populations of <i>Penaeus semisulcatus</i>

Abstract

Penaeus semisulcatus, a commercially valuable aquaculture species, is widely distributed along the southeastern coast of China and throughout the South China Sea. Despite its economic importance, the comprehensive understanding of its germplasm characteristics remains limited. This investigation evaluated nutrient profiles, amino acid composition, lipid constituents, antioxidant capacity, and genomic variability across three farmed aquaculture populations maintained under standardized environmental parameters to discern divergence in nutritive attributes and hereditary characteristics. The results revealed significant interpopulation variation in ash content (p p P. semisulcatus shows great potential for aquaculture development. These findings provide valuable insights for future germplasm improvement and aquaculture optimization efforts, offering a scientific basis for refining breeding strategies and enhancing the nutritional evaluation of P. semisulcatus. Additionally, the comparative analysis of genetic diversity and biochemical composition contributes to a better understanding of population variation, which is essential for the sustainable management and utilization of this species in aquaculture.
