人工养殖大鲵全长与体重关系的回归分析

Regression Analysis of Whole Length and Body Weight of Giant Salamanders(Andrias davidianus) under the Condition of the Artificial Breeding

大鲵(Andrias davidianus)隶属两栖纲,有尾目,隐鳃鲵科,大鲵属,为我国特有的珍稀濒危两栖动物。目前在我国一些主要历史分布区掀起了一股大鲵养殖高潮,但是对当前养殖效果缺乏成熟的评价手段,因此本研究通过对陕西省汉中市和安康市两大鲵养殖场养殖的1530尾大鲵的体重和全长进行实际测量,利用SPSS分析软件对数据进行了回归分析。结果表明,体重与全长之间存在极显著的相关关系,体重与全长之间的关系主要表现为幂函数关系,其关系式为:Y=0.010X2.867。本研究的顺利完成,为今后评价大鲵的人工养殖效果提供了科学的方法。

Giant salamanders （A n drias dav idianus）, which is Amphibia, Caudata, salamander Cryptobranchus Branch, Megalobatrachus, is a unique endemic amphibious in China. Recently, breeding giant salamanders in historical distribution areas is a hot spot, however, the assessment methods of breeding effects are still rare. This essay analyzed the whole length as well as the weight of 1 530 giant salamanders using regression analysis in SPSS analysis software. The results indicated that there was a significant correlative relation between the weight and the whole length of giant salamanders. The formula was Y=0.010X2867. In conclusion, this article provided a scientific method to assess the status of giant salamander via artificial breeding.
