摘　　要：选取长江野生、湖泊放流、网围养殖、池塘养殖4种生态环境的同规格成蟹,对其进行64个肉脂品质指标的测算.结果表明,组内雌、雄可食部分比例、粗脂肪、灰分、脂肪酸、微量元素等指标差异较小;水分、粗蛋白、氨基酸等指标差异较大,粗蛋白、氨基酸各有显著差异的指标均为雄蟹小于雌蟹.同性别不同生态环境成蟹粗蛋白、氨基酸各指标的差异较小;可食部分比例、粗脂肪、水分、灰分、脂肪酸、微量元素等指标差异较大.综合均值比较结果和实践经验分别选取13个和16个指标,对4组雄蟹、4组雌蟹进行判别分析.判别结果表明所选取指标可较好反映中华绒螯蟹肉脂品质的差异.Yangtze River wild, shallow lake propagation, net cultured and pool cultured Chinese mitten crab mature individuals are collected, with 5 males and 5 females for each kind of ecological environment, and they are analyzed in 64 meat quality parameters. Within the group, the female and the male are similar in parameters of edible proportion, lipid, ash, fatty acid and microelements. However, they are obviously different in parameters of water, protein and amino acids. The males are always significantly lower than the females in protein and amino acids parameters with significant differences. Chinese mitten crab mature individuals of the same sex from different ecological environments are similar in parameters of protein and amino acids and obviously different in parameters of edible proportion, lipid, water, ash, fatty acid and microelements. Discriminant analysis with selected 13 and 16 parameters, according to means comparison results and practice experience of four groups of females and males shows that the parameters can reflect the differences well of meat quality of Chinese mitten crabs.
