摘  要：
大鲵(Andrias davidianus)是我国特有的珍稀濒危物种,其人工繁殖率低,其中,主要原因有:大鲵雌雄性腺发育不同步、性腺发育成熟率低、精子活力差以及催产率、受精率和孵化率不高等。对大鲵人工繁殖过程中的主要制约因子进行分析,提出制约大鲵人工繁殖率的关键因素是水温、水流、光照和饵料,并结合安徽省黄山市休宁县珍稀水生动物研究所2002—2010年的大鲵人工繁殖实践提出了具体参数,以期为大鲵人工繁殖技术的研究和实践提供参考。

摘  要：
Andrias davidianus is one kind of endemic rare and endangered species in China.The main reasons for the low rate of artificial propagation of A.davidianus include asynchronous development of male and female gland in A.davidianus,low development and maturation rate of gonad,low sperm motility,low induced-spawning rate,low fertilization rate,low incubation rate and so on.The main limiting factors in the artificial propagation process of A.davidianus.It was put forward that the key factors that restricted the artificial propagation rate of A.davidianus were water temperature,water flow,lighting and bait.Some concrete parameters were proposed on the basis of the artificial propagation practice of A.davidianus from 2002 to 2010 in Institute of Rare Aquatic Animals in Xiuning County of Huangshan City in Anhui Province,so as to provide reference for the research and practice of the artificial propagation technique of A.davidianus.
