摘要
从南水水库收集鲂鱼 193尾 ,进行繁殖力的研究 .材料均通过常规的生物学测量及年龄鉴定 ,同时取IV～V期卵巢进行怀卵量的测定 ,求出相应的绝对繁殖力和相对繁殖力 .从性腺发育状况、个体繁殖力和生殖群体组成等方面分析说明 ,南水水库鲂鱼的个体绝对繁殖力随年龄增长而增长 ,而体长、体重等也对繁殖力有一定的影响 .
We got 193 Megalobrama Skolkovii from the Nanshui reservoir to study fecundity,measured their body length and weight etc, justified the ages and the total spawn so as to get absolute fecundity and relative fecundity. From the experiment results, we conclude that the absolute fecundity increases by the ages. The fecundity is also affected by the body length and weight etc.
