棘胸蛙产卵量、卵子孵化率的比较研究

为选择适于闽北的棘胸蛙养殖品种,比较了异地引种棘胸蛙和本地引种棘胸蛙的产卵量和卵子孵化率。试验表明,异地经过几个世代驯化的棘胸蛙在总产卵量上要比本地引种的棘胸蛙要多两倍多,产卵总数为3071枚,本地引种的棘胸蛙产卵总数为863枚。异地引种棘胸蛙在卵子孵化率上也比本地引种棘胸蛙要高,平均为95.3%,而本地引种的棘胸蛙的卵子孵化率仅为64.18%,说明异地引种的棘胸蛙在闽北有较好的推广前景。

Comparison research of the quantities of spawning and hatching rate between two kinds of Rand spinasa

This paper offers the comparison between two kinds of Rana spinasa about the quantities of spawning and hatching rate.One was breed in Zhejiang university,the other was raised in Jianou,Nanping.And one experiment was conducted.The experiment shows that the quantities of spawning of the former kind,whose several generations of ancestors had been tamed,was much more than that of the latter kind,and the total number of spawning of the former kind is 3071,but that of the latter kind is 863.The experiment also shows that the hatching rate of the former kind,which is 95.3%,is higher than that of the latter kind,which is 64.18%.
