摘　　要：4个种群日本沼虾(Macrobrachium nipponensis)于2001年8月分别取自太湖、洪泽湖、广西南宁3地天然水域及浙江德清养殖种群。肌肉营养成分测定结果表明,养殖种群的粗蛋白含量为(15.83±0.32)％(质量分数),显著低于3个野生种群(P<0.05),而粗脂肪质量分数为(1.37±0.02)％显著高于野生种群(P<0.05)。3个野生种群中洪泽湖种群鲜味氨基酸含量最高;但太湖种群粗蛋白含量(17.71±0.38)％最高,必需氨基酸组成最为均衡,且单不饱和脂肪酸总量和多不饱和脂肪酸总量均为最高,分别达25.904％和35.953％。比较得出太湖种群日本沼虾肌肉的营养品质最高,养殖种群最低。The four populations of Macrobrachium nipponensis were from nature water areas of Taihu Lake (PT), Hongze Lake(PH) and Guangxi(PG), and the culture ponds of Deqing Zhejiang(PC) , respectively. The capture was conducted in August 2001. As a result, PC had the lowest crude protein content(15. 83±0. 32)% .significantly different from the other three natural populations(P<0. 05) , while its crude fat content(1. 37 ±0.02)% was significantly higher than the other three (P <0.05). Among the three natural populations, PH had the highest content of delicious amino acids,but PT had the highest content of crude protein( 17.71 ±0.38)% and its essential amino acids composition was the most balanced. Moreover,PT had the highest content of monounsaturated fatty acids and polyunsaturated fatty acids, reaching 25.904% and 35.953% Respectively. In conclusion, the nutritional quality of PT is the best,while PC the worst.
