摘要
为性成熟子二代大鲵亲体的人工繁育选苗提供科学指导,本文通过对陕西省汉中市和广东大有大鲵驯养繁殖有限公司自繁123尾性成熟子二代亲体的体质量和全长进行实际测量,利用matlab分析软件对数据进行回归建模分析。结构表明,性成熟子二代体质量和全长直接存在极显著的相关关系,子二代养殖大鲵亲体的体质量和全长直接的主要关系可以用幂函数:y=0.00001129x^(3.312)和三次曲线:y=39400-136.2x+0.1521x^2-0.00004544x^3表达。
In order to support the artificial breeding of sexual maturity giant samanders （A ndrias davidianus）F2,this paper analyzed the whole length as well as the weight of 123 sexual maturity giant samanders F2 using regression model by matlab software. The results indicated that there was a significant correlative relation between the weight and the whole length of sexual maturity giant samanders F2. The relationship between the weight and the whole length of sexual maturity giant samanders F2 couht be modeled by Power,Quadratic and cubic polynomial curve.
