Longfin batfish (Platax teira) is a coastal marine fish life. The aims of this study are to investigate the compositions and content of amino acid and fatty acid in three parts of P. teira. The results showed that P. teira muscle protein content was as high as 21.00%. For amino acid composition, seventeen kinds of amino acids were detected in three parts. The essential amino acid score (EAAS) and essential amino acids (EAA) / total amino acids (TAA) ratio of P. teira were both above 70 and 0.4. EAAS in the upper part of the abdominal muscle showed higher than those two parts. The content of saturated fatty acids (SFA) and the polyunsaturated fatty acids (PUFA) in the upper part of the abdominal muscle was higher than that in other groups. No significant differences in monounsaturated fatty acids (MUFA) and n-3/n- 6 were detected among three parts. Overall, the upper part of the abdominal muscle was thought to have a higher nutritious value. These results showed P. teira is a high quality marine fish with high protein content and low fat, abundant amino acids with proper proportion, however, it was regarded as an excellent breeding varieties.
