摘　　要：目的：本研究探讨了人工养殖条件下水蛭（日本医蛭）的繁殖性能,以期为规模化繁殖水蛭提供基础资料。方法：以实验室养殖的水蛭亲蛭为实验材料,研究了水蛭产茧数、卵茧质量、幼蛭孵化数,以及亲蛭质量、亲蛭密度对水蛭繁殖性能的影响。结果：水蛭平均产卵茧数为0.9000±0.5525枚,最少为0枚,最大量为2枚,单枚卵茧孵化最少有3尾,最大量为21尾。卵茧质量绝大多数介于0.05~0.25 g之间,初孵幼蛭的体长分布为0.82~1.55 cm,平均体长为1.21±0.22 cm。亲蛭质量、密度以及卵茧质量与水蛭的繁殖性能有显著相关性。结论：水蛭繁殖性能较低,人工养殖情况下,应该仔细挑选适当质量和年龄的亲蛭,同时要选择合适的繁殖密度来提高水蛭的繁殖性能。Objective ：To investigate the reproductive performance of Hirudo nipponica under artificial cultivation, in order to pro- vide reference for the commercial rearing and breeding industry of this species. Methods ： The mean number of cocoons, cocoon weight, hatching numbers of cocoons, and the effect of parent leeches weight and density on reproductive performance were investigated. Results ： The mean number of cocoons produced by parent leeches was 0. 9000 ± 0. 5525, the range was from 0 to 2. The hatching number of cocoons were between 3 and 21 ,and the weight of cocoons were from 0. 05 to 0.25 g. Length of newly hatched ju- venile was 1.21 ±0. 22 cm,and the range was from 0. 82 to 1.55 cm. It was found that the parent leeches weight,density and the co- coons weight were positively correlated to the reproductive performance of Hirudio nipponica. Conclusion ： In artificial cultivation, moder- ate weight, age and density of parent leeches is necessary to be chose for increasing the reproductive performance of Hirudio nipponica.
