| 摘 要： | 在土壤温度为24℃～26℃下，采用网箱湿土养殖法对具有生殖环带的宽体金线蛭（Whitmania pigra）进行了繁殖试验，统计了水蛭减重率、成活率和产茧率。在室内温度为26℃～28℃下，采用水箱孵化法孵化宽体金线蛭所产的卵茧，统计卵茧孵化率。结果表明：产茧后的宽体金线蛭平均减重率和成活率分别为43.5±1.41%和87.5±6.36%；宽体金线蛭平均产茧量和卵茧孵化率分别为1.22±0.04枚/条和73.1±0.57%。

| Abstract: | Leech Whitmania pigra with a clitellum was artificially propagated under the condition of soil temperature 24℃-26℃ in a wet soil bottom net cage, and the weight loss rate, survival rate and cocoon number per leech were estimated. The mucus cocoons with eggs and sperm were incubated in a tank at indoor temperature of 26℃-28℃ and the hatching rate was estimated. The average weight loss rate was found to be 43.5 ± 1.41%, and survival rate 87.5± 6.36%. The？leech had 1.22± 0.04 cocoon in number individually with hatching rate of 7 3.1 ± 0.57%. |
