摘要： A comparative analysis was performed to assess the histological characteristics and nutrient components of the muscles in regular and yellow Triplophysa siluroides. The yellow T. siluroides had smaller muscle fiber diameter (P > 0.05) and higher density (P > 0.05) in their dorsum muscles. Compared to the regular T. siluroides, the yellow T. siluroides showed a slightly greater (P > 0.05) moisture content and a significantly lower (P < 0.05) crude lipid content. The total amino acids, essential amino acids, nonessential amino acids, and delicious amino acids content were significantly greater (P < 0.05) in the muscles of yellow T. siluroides than regular T. siluroides. Leucine was identified as the primary limiting amino acid in both species based on amino acid score (AAS) and chemical score (CS) evaluations. Significant differences (P < 0.05) were observed in total saturated fatty acids (Sigma SFA), total monounsaturated fatty acids (Sigma MUFA), and total polyunsaturated fatty acids (Sigma PUFA) between the regular T. siluroides and yellow T. siluroides. Notably, the DHA content was significantly greater (P < 0.05) in yellow T. siluroides. Overall, yellow T. siluroides demonstrated superior nutritional quality compared to that of regular T. siluroides, making it a high-quality food source suitable for human consumption.
