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
