Abstract: Juvenile Chinese mitten handed crab Eriocheir sinensis with red color shell(A),juvenile Chinese mitten handed crab with normal color shell(B)from red crab family,juvenile Chinese mitten handed crab Guanghe No. 1(C),precocious juvenile Chinese mitten handed crab(D)and inbreeding precocious juvenile Chinese mitten handed crab(E)were reared in three culture models including indoor intensive model,individual culture model, and rice field model to compare their growth performance.The results showed that the juvenile crab in group A had survival rate of 35.8%,significant difference from just group D(P＜0.05),and with coefficient of variation(CV) of 27%in carapace width(CW),significant different from other breeding families in the indoor intensive model (P＜0.05).There was SGR of 7.0%/d in the juveniles in group A,without significant difference among all breeding families(P＞0.05).In the individual culture model,however,the juveniles in group A had survival rate of 86.7%,significant different from the juveniles in group B and group E(P＜0.05),with the CV of 52%in CW in group A,very significantly differentfrom groups C and D(P＜0.01).There was SGR of 5.7%/d in group A,significant difference among roups A,B,C and E(P＜0.05).The minimal survival rate(3.2%)was observed in the juvenile crab in group A,very significantly different from groups B,C,and D(P＜0.01).The juveniles in group A had CV of 12%(the minimum)in CW in group A,significant difference between group A,and groups D and E (P＜0.05).There was SGR of 8.05%/d in group A,without significant difference among all families(P＞0.05). It is concluded that the significantly higher survival rate was in the juveniles in group A in the individual culture model,which more information about the breeding family could be obtained.
