Abstract: The impact of the current aquaculture environment on the artificial reproduction and juvenile crab growth of Charybdis feriatus was studied, and the breeding density test, bait test and shelter test were conducted. The results showed that, ①the weight of Charybdis feriatus juvenile crab in each stage increased first and then decreased with the increase of breeding density. In the second stage, the weight of D2 group juvenile crab was the largest, indicating that the breeding density of 150 per square meter could ensure the normal development of juvenile crab weight; ②The biological feed feeding group had the lowest body weight of Charybdis feriatus juvenile crab, while the mixed feed feeding group had the highest body weight of Charybdis feriatus juvenile crab. The biological feed feeding group had the lowest shell width and length, and the survival rate of Charybdis feriatus juvenile crab was inversely proportional to the incubation period of the juvenile crab; ③There was a significant difference in the body weight of Charybdis feriatus juvenile crab between different shading test groups. The S1 and S3 groups of Charybdis feriatus juvenile crab had higher body weight values. Under the condition of no shelter, the body weight value of the Charybdis feriatus was the lowest.
