| 摘 要： | 研究了中华鳖(Pelodiscus sinensis)人工繁殖不同雌雄配比的受精率差异,结果显示:在放养密度3750~4500 kg/hm2,亲鳖规格♀1.5 kg/只、♂2.0 kg/只条件下,雌雄配比可达8∶1。在不增加水体面积和投资情况下,雌雄比8∶1与5∶1相比多产受精卵13500~18000枚/hm2,可增加纯利润27000~30000元/hm2。

| Abstract: | The paper studied the effect of different female/male ratios on the fecundation rate of Chinese soft-shelled turtle Pelodiscus sinensis in artificial propagation,the main results were as follows: the ratio of male to female could be up to 8∶1 under the conditions of stocking density 3750~4500 kg/hm2,female parent 1.5 kg/head and male parent 2.0 kg/head.Under no increasing water body area and investment,the treatment which the ratio of male to female was 8∶1 could obtain 13500~18000/hm2 more spermatovums and 27000~30000 yuan/hm2 more pure profit than the treatment which the ratio of male to female was 5∶1. |
