摘要: 为研究雌雄分养对克氏原螯虾(Procambarus clarkii)养殖效果的影响,分析全雌性、全雄性和雌雄混养3种养殖模式下克氏原螯虾生长、存活、伤残以及性腺发育情况。结果表明,养殖模式对克氏原螯虾体重无显著影响(P>0.05);在养殖90 d时,全雌性养殖存活率最高,为74.17%,伤残率最低,为5.62%;雌雄混养模式下,雄虾平均体重始终高于雌虾,雌虾存活率和伤残率则始终高于雄虾;全雌组雌虾性腺发育程度高于雌雄混养组。

关键词: 克氏原螯虾(Procambarus clarkii), 雌雄分养, 养殖效果, 性腺发育

Abstract: In order to explore the effect of Procambarus clarkii culture, the growth, survival, disability and gonad development of Procambarus clarkii were investigated under three culture modes including female mono-sex, male mono-sex and mixed culture. The results showed that there was no significant effect on body weight of Procambarus clarkiiP>0.05) under different aquaculture modes, the survival rate of female mono-sex on the 90th day was the highest (74.17%) and the disability rate was the lowest (5.62%), the average body weight of male crayfish in mixed culture was always higher than that of female crayfish, while the survival rate and disability rate of female crayfish were always higher than those of male crayfish, and the gonad development degree of female crayfish in female mono-sex was higher than that in mixed culture.

Key words: Procambarus clarkii, isolating female from male culture, culture effect, gonad development
