摘　　要：为研究养殖环境对锈斑蟳人工繁殖及其仔蟹生长的影响,进行了养殖密度试验、饵料试验及其遮蔽物试验。结果表明,(1)锈斑蟳仔蟹各阶段体重随着饲养密度增加呈先增加后减少的趋势,第二阶段D2组仔蟹的体重最大,150只/m^(2)的养殖密度可以保证仔蟹正常发育;(2)生物饵料饲养组锈斑蟳仔蟹体重最低,锈斑蟳仔蟹体重最高的为混合饲料喂养组,锈斑蟳仔蟹壳宽和壳长最低的为生物饵料喂养组,锈斑蟳仔蟹存活率与仔蟹培育阶段时间成反比;(3)不同遮蔽物试验组之间锈斑蟳仔蟹体重具有明显差异。S1组以及S3组锈斑蟳仔蟹体重较高。无遮蔽物情况下,锈斑蟳体重最低。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.
