The nutritional components and quality in muscle of cultured Synechogobius ommaturus were analyzed and evaluated by biochemical analysis methods. The results showed that the moisture, crude protein, crude fat, and crude ash contents of fresh muscle of S. ommaturus were (82.10±0.21)%, (15.34±0.20)%, (0.87±0.13)%, and (1.12±0.03)%, respectively. Glu (12.71%), Asp (8.42%), Lys (8.16%), and Leu (6.51%) were the highest contents in 18 kinds of found amino acids in dry muscle. Total amino acid (TAA), total essential amino acid (EAA), and total delicious amino acid (DAA) contents of dry muscles were 83.36%, 31.40%, and 31.79%, respectively. The EAA/TAA and EAA/NEAA were (37.65±0.63)% and (70.10±1.90)%, respectively; according to nutrition evaluation in amino acids score (AAS) and chemical score (CS), the first limited amino acid was Trp, the second limited amino acid was Val; the essential amino acid index (EAAI) and the ratio of branched chain amino acid to aromatic amino acid (F value) were 70.19% and 2.22, respectively. The saturated fatty acids (∑SFA), poly-unsaturated fatty acids (∑PUFA), ∑n3 PUFA, and EPA+DHA were (30.23±0.48)%, (49.52±0.91)%, (39.54±1.12)%, and (42.47±1.10)%, respectively. Therefore, S. ommaturus is nutritional, delicious, and healthy to human, and is a new potential candidate for aquaculture.
