摘 要 ：施氏鲟天然繁殖水温为 1 6～ 1 9℃ ,在 8～ 1 4℃水温中进行人工繁殖 ,获得成功 ,催产率 85 %。在低温环境 (8～ 1 4℃ )中催产 ,效应时间内水温基本稳定或升高是催产成功的关键 ,而温度高低与催产成功率没有明显关系。在低温环境中 ,催产的效应时间大幅度延长 ;卵母细胞游离速度十分缓慢 ,应多次少量注射激素 ,催产才能完全成功 ;催产激素剂量以怀卵量计算效果较佳 ;孵化积温非常数。神经胚期胚胎在水温低于 1 1℃时畸形死亡 ,孵出期胚胎在水温达 1 3℃才能正常破膜 ,其它时期胚胎在 8.5℃水温中能正常发育。

Abstract:The natural reproduction water temperature of Acipenser schrencki is1 6～ 1 9℃ .We have success- fully in the sturgeons made artificial reproduction of Acipenser schrencki in water temperature of 8～ 1 4℃ with induced ovulation rate of85 % .Under environment of lower temperature(8～ 1 4℃ ) ,the key factors for successfully induced ovulation were either to keep constant water temperature to increase water tem- perature during the effect time of induced ovulation.The success of induced ovulation had no evide...
