为了了解养殖斑尾复虾虎鱼肌肉的营养特征，本试验旨在采用生化分析的方法，对养殖斑尾复虾虎鱼肌肉的营养成分进行测定和分析。结果表明：养殖斑尾复虾虎鱼的肌肉水分、粗蛋白质、粗脂肪、粗灰分含量分别为（82.10±0.21）%、（15.34±0.20）%、（0.87±0.13）%和（1.12±0.03）%。肌肉干样中含有18种常见的氨基酸，其中含量最高的4种氨基酸依次分别为谷氨酸（12.71%）、天冬氨酸（8.42%）、赖氨酸（8.16%）和亮氨酸（6.51%）。肌肉中氨基酸总量（TAA）达83.36%，其中必需氨基酸（EAA）含量为31.40%，鲜味氨基酸含量为31.79%。EAA/TAA和EAA/非必需氨基酸分别为（37.65±0.63）%和（70.10±1.90）%。第一和第二限制性氨基酸分别为色氨酸和缬氨酸，必需氨基酸指数为70.19%，支链氨基酸与芳香族氨基酸的比值为2.22。肌肉中饱和脂肪酸和多不饱和脂肪酸含量分别为（30.23±0.48）%和（49.52±0.91）%；肌肉中二十碳五烯酸（EPA）+二十二碳六烯酸（DHA）含量为（39.54±1.12）%，n3多不饱和脂肪酸含量为（42.47±1.10）%。由此可知，养殖斑尾复虾虎鱼肉质鲜美，富含营养价值和保健功能，是值得推广养殖的名优品种。
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.
