Abstract: Nutritiona1 components of Anguilla bicolor pacifica muscle were analyzed with routine methods. The results showed that contents of moisture, crude protein from fresh muscles were 62.56% and 15.85%. Except Tryptophan, 17 common amino acids were detected from muscles which include 7 essential amino acids (EAA) for human body. In dry sample, the total content of amino acids (TAA) was 36.33%, the content of EAA was 13.99%. The constitutional rate of the essential amino acids accorded with the FAO/WHO standard. The main limited amino acids of A. bicolor pacifica were Methionine+Cysteine and Valine. The essential amino acids index (EAAI) was 78.26. Five kinds of delicious amino acids (DAA) accounted for 16.58% in dry sample. The content of monounsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA) in fatty acids were 44.41% and 16.70%. The total content of EPA (C20:5n-3) and DHA (C22:6n-3) in fatty acids was 7.33%. The result showed that A. bicolor pacifica had high edible value and health effect, and would be an important cultured species in the future.
