为了比较野生与养殖刀鲚(Coilia nasus)肌肉营养成分差异，利用常规方法对野生（捕自长江靖江段）和养殖刀鲚（以活饵为食）肌肉的一般营养成分和氨基酸含量进行测定。结果表明，野生刀鲚肌肉鲜样中粗蛋白质和灰分含量均显著低于养殖刀鲚（P<0.05），而粗脂肪含量为则显著高于养殖刀鲚（P<0.05），两者的水分含量无显著差异（P>0.05）。野生和养殖刀鲚肌肉鲜样中均测出18种氨基酸，但在含量上养殖刀鲚绝大多数氨基酸均显著高于野生刀鲚(P<0.05)。其中，养殖刀鲚氨基酸总量高出野生刀鲚11.97%，鲜味氨基酸总量高出野生刀鲚14.12%。根据氨基酸评分（ASS）和化学评分（CS），野生和养殖刀鲚的第一限制性氨基酸均为色氨酸，而养殖刀鲚的必需氨基酸指数(EAAI)显著高于野生刀鲚 (P<0.05)。由此得出，以活饵为食的养殖刀鲚，其营养品质不会降低，完全可以替代野生刀鲚。

In order to compare the differences in muscle nutrient composition between wild and cultured Coilia nasus, the amino acid composition and common nutrient composition in muscle of wild (captured in Jingjiang section of Changjiang) and cultured Coilia nasus (fed live bait) were determined by routine methods. The results showed as follows: compared with the wild Coilia nasus, crude protein and ash contents in fresh muscle of cultured Coilia nasus were significantly increased (P<0.05). In contrast, the crude fat content in fresh muscle of wild Coilia nasus was significantly higher than that of cultured Coilia nasus (P<0.05). There was no significant difference in moisture content in fresh muscle between wild and cultured Coilia nasus (P>0.05). Both wild and cultured Coilia nasus had 18 kinds of amino acids. Compared with the wild Coilia nasus, the contents of most amino acids in fresh muscle of cultured Coilia nasus were significantly higher (P<0.05). Additionally, the contents of total amino acids and delicious amino acids of cultured Coilia nasus were significantly higher than those of wild Coilia nasus (P<0.05). Base on the criteria of amino acid score (ASS) and chemical score (CS), the first limiting amino acid of the two groups was tryptophan, and cultured Coilia nasus exhibited a higher essential amino acid index (EAAI) than wild Coilia nasus. In conclusion, the nutritional quality of cultured Coilia nasus which were fed live baits is not decreased, and the wild Coilia nasus can be substituted by cultured Coilia nasus.［Chinese Journal of Animal Nutrition，2011，23（3）：514-520］
