大鲵人工繁殖过程中,同一群体的亲鲵发育成熟的时间差距较大,给人工繁殖造成一定难度,把握好催产时机是提高催产成功率的关键。近年来,我们在大鲵人工繁殖过程中遇到一些问题,也取得了一些经验,现总结如下:1材料与方法亲鲵选择Ⅵ龄以上,大部分个体4～10kg,体格健康,肉眼观察、手摸明显有性腺发育特征。亲鲵来源有本地野生和纯人工养殖两种类型,
In the process of artificial breeding, the time difference between the same group of progenitor cells maturing is relatively large, which causes some difficulties for artificial breeding. To grasp the timing of oxytocin is the key to improve the success rate of oxytocin. In recent years, we encountered some problems during the artificial breeding process and also obtained some experiences. The main conclusions are as follows: 1 Materials and methods: 亲 鲵 choose Ⅵ age above, most of the individual 4 ~ 10kg, physical health, naked eye observation, hand Touch obvious gonadal development characteristics. There are two types of pro-mongrim native wild and pure farmed,
