摘　　要：[目的]比较不同池塘养殖模式草鱼的肌肉营养成分和氨基酸组成。[方法]研究鱼菜共生养殖模式、高密度精养模式和山塘不投饵养殖模式3种池塘养殖模式对草鱼肌肉营养成分及氨基酸组成的影响。[结果]3组草鱼的脏体指数为10.81%～12.28%,肝体指数为2.16%～2.68%,肥满度为1.61%～1.92%;3组草鱼肌肉中水分、灰分、粗蛋白和粗脂肪含量差异均不显著(P>0.05);3组均测得18种常见氨基酸,氨基酸总量为170.0～203.3 g/kg,其中8种人体必需氨基酸的含量为69.6～84.1 g/kg,占氨基酸总量的40.93%～41.80%;4种鲜味氨基酸占氨基酸总量的35.39%～36.64%。[结论]该研究可为草鱼池塘养殖品质的提升提供参考。[Objective] To study the nutritional components and amino acid composition in the muscle of grass carp under different pond culture models.[Method] The effects of symbiotic culture of fish and vegetables, high-density intensive culture and non-bait culture fish on the nutritional components and amino acid composition in the muscle of grass carp were studied.[Result] The organ index of grass carp in three groups was 10.81%-12.28%, and the liver index was 2.16%-2.68%, relative fatness was 1.61%-1.92%. There was no significant difference in the contents of moisture, ash, crude protein, and crude fat in the muscles ( P >0.05). All 18 kinds of common amino acids were measured in three groups , and the total amount of amino acids was 170.0-203.3 g/kg. The content of 8 kinds of essential amino acids for human body was 69.6-84.1 g/kg, accounting for 40.93%-41.80% of the total amino acids. 4 kinds of delicious amino acids accounted for 35.39%- 36.64% of the total amino acids.[Conclusion]This study could provide reference for improving the pond culture quality of grass fish .
