Eriocheir sinensis with the initial body weight(8.65 + 0.64)g were selected as the research animals and were fed three diets(fermented soybean meal group,ordinary material 1 group,ordinary material 2 group)in the indoor cultivation experiment for 5 weeks,then the growth performance,body composition and free amino acids in muscle of the crabs were detected for assessing the effects of the three diets. The results showed that :Shell length,shell width,weight gain rate,specific growth rate and feed coefficient were no significantly difference among all groups(P 0.05),but the survival rate of the crabs in fermented soybean meal group was significantly higher than other groups(P 0.05). There were no significant difference among all groups in muscle crude protein,crude fat and crude ash(P 0.05). The free amino acids concentrations and total flavor free amino acids concentrations in muscle of fermented soybean meal group were lower than the ordinary material 1 group,but were higher than ordinary material 2 group. While the percentage of total flavor free amino acids in the total free amino acids were greater than the other two groups. The results showed that feeding fermented soybean meal could improve the survival rate and muscle flavor of Eriocheir sinensis.
