摘    要:采用形态学测量和生化分析等方法,比较了野生和池塘养殖条件下长江水系中华绒螯蟹扣蟹的形态学、肝胰腺指数(HSI)、常规生化组成和脂肪酸组成。结果发现:野生和池塘养殖扣蟹的形态学特征差异较大,雌雄个体均有4个贡献较大的主成分(PC1,PC2,PC3,PC4),其中PC1的贡献率均远高于其他主成分,两者PC1分别由16和19个主要影响变量构成;所测36个形态学指标中,两群体雄蟹和雌蟹分别有25和22个形态学指标差异显著,进一步筛选判别贡献率较大的4~5个指标分别建立判断方程,综合判别准确率达95%以上;野生扣蟹的HSI、组织中总脂、躯体肌肉的16:0、18:1n9和20:4n6含量均高于池塘养殖扣蟹,后者组织中水分含量、躯体肌肉中的18:0、20:5n3和22:6n3高于前者。研究表明,野生和池塘养殖扣蟹的形态学和生化组成均存在较大差异,可以根据两群体扣蟹的形态学差异和判别方程鉴别两种扣蟹蟹种。

关 键 词:中华绒螯蟹  扣蟹  野生捕捞  池塘养殖  形态学  生化组成

Abstract:Based on the morphological measure ment and biochemical analysis,this study was conducted to compare the morphology,hepatosomatic index (HSI) and biochemical composition between wild-caught (WC) and pond-reared (PR) juvenile Eriocheir sinensis.The results showed that:the significant differences were found on the morphology of WC and PR.There were four of dominated principal component (i.e.PC1-PC4) for both females and males.PC1 contributed more significantly to the principal component analysis than the other PC,and PC1 of both gender consist of 16 and 19 main variables,respectively.Among the 36 morphological indices,there were 25 and 22 indices with significant differences between WC and PR,for males and females.Four to five indices were further selected to establish discriminant equation,and those equations had more than 95% of accuracy for distinguishing WC and PR.WC had the higher HSI,tissue total lipids,muscular 16:0,18:1n9 and 20:4n6 levels,but the lower moisture contents,muscular 18:0,20:5n3 and 22:6n3 levels than PR.Therefore,the effective identification methods are established based on their morphology and biochemical composition between WC and PR.
Keywords:Eriocheir sinensis  juvenile  wild-caught  pond-reared  morphology  biochemical composition
