摘  要：
为有效确认非阳澄湖产"洗澡蟹"与阳澄湖原产中华绒螯蟹(Eriocheir sinensis)背甲形态的差异,研究运用几何形态分析法,比较研究了前者在阳澄湖中人为"洗澡"式养殖1个月始末时,其与阳澄湖原产蟹的背甲形态特征。背甲的形态分析基于所建立的35个地标点系统来进行,即背甲经图像处理后提取地标点坐标,开展相对扭曲主成分以及判别分析,再利用薄板样条分析和网格变形将形态变异矢量可视化。相对扭曲得分的逐步判别分析结果显示:"洗澡"式养殖前后阳澄湖原产蟹与非阳澄湖产蟹背甲形态差异均极其显著,判别准确率均为100%。网格变形结果进一步发现,与非阳澄湖蟹情况不同,"洗澡"式养殖前后的阳澄湖产蟹背甲形态变化不显著。研究首次定量证实,非阳澄湖产中华绒螯蟹即使在阳澄湖"洗澡"式养殖1个月,背甲形态仍无法与原产蟹趋同。这种差异性具有区别阳澄湖原产和"洗澡"蟹的应用潜力。

摘  要：
To explore carapace difference between Yangcheng Lake originated Eriocheir sinensis and one-month"bathed" E. sinensis crabs, landmark-based geometric morphometric analysis was used to comparatively study the carapace characteristics of the two type crabs in Yangcheng Lake. The carapace morphology was characterized by a 35-landmark point system. After image and the punctuation coordinates were processed, relative distortion and discriminant analysis were performed. Later, the morphological variation vector was visualized by using spline analysis and mesh deformation. The stepwise discriminant analysis of relative distortion scores showed that the discrimination accuracies for both Yangcheng Lake originated and "bathed" E. sinensis crabs were 100% at before and after bathing. According to the grid deformation diagram, there was no significant change in the carapace morphology of Yangcheng Lake originated crabs during one month period, unlike the situation of the "bathed" crabs. This study reveals for the first time the carapace difference between natively originated and one-month bathed E. sinensis crabs in Yangcheng Lake, which has a strong application potential for effectively distinguishing the latter from the former E. sinensis.
