A completely randomized block designed experiment and mixed linear model were used to evaluate the survival and growth of mitten crab of Yangtze population and Liaohe population at juvenile stage. The results indicated that: (1) The survival rate and weight increasing rate of Yangtze population were slightly higher than those of Liaohe population, but there were no significant difference(P>0.05). (2)The result of linear model revealed that monthly growing rate was no significant difference between Yangtze population and Liaohe population. Although significant differences didn't exist between male and female crab, monthly growing rate of male crab were always higher than that of female crab. (3) the variation of body weight of two populations among individuals were very large(more than 40), and the variation of Yangtze population was slight higher than that of Liaohe population, but no significant difference was found(P>0.05).
