[Objective] The study aimed to determine and analyze the flesh rate and the muscle nutrition component and nutritional value in Squaliobarbus curriculus Richardson.[Method] With 10 health S.curriculus as tested materials,the flesh rate and the muscle nutrition component (moisture,crude protein,crude fat,ash) and nutritional value (amino acid composition and content) in S.curriculus were measured and analyzed.[Result] The average flesh rate of S.curriculus was 74.64%±0.43%.In the fresh samples of muscle,the crude moisture,crude protein,crude fat,calcium and phosphorus were 75.42%,18.05%,4.95%,0.50% and 0.48% resp.In the dry sample of muscle,the crude moisture,crude protein mass fraction,crude fat mass fraction,ash mass fraction,Ca and P were 30.75%,72.52%,15.35%,0.08%,0.86% and 1.28%.the total content of 18 kinds of amino acids was 74.89% (mass fraction,dry weight),in which the total content of 10 kinds of essential amino acid was 34.54%,accounting for 46.12% of the total amount of amino acids,the total content of 4 kinds of flavor amino acid was 27.89%.[Conclusion] Comparison with several other economic fish species showed that S.curriculus was a kind of good freshwater fish specie with the higher nutritional value,which was worth to development and domestication.
