摘要
以锈斑蟳(Charybdis feriatus)为研究对象,将锈斑蟳发育阶段分为T1、T2、T3、T4、T5、T6及M期7个阶段进行锈斑蟳人工育苗试验。结果表明,①从蟹苗平均阶段存活率来看,秋季和春季育苗存活率最高是T1期,为100%;存活率最低是幼体发育阶段,为42.5%;其次是大眼幼体阶段,为51.1%,在锈斑蟳育苗过程中,T6期变态为大眼幼体以及大眼幼体变态为Ⅰ期幼蟹是最重要的时期。②锈斑蟳到T3期蟹苗在春季和秋季的总体存活率为48.1%,T6期变态为大眼幼体时期的总体存活率为11.4%,最后发育成为I期幼蟹的育苗总体存活率为5.0%。
Taking Charybdis ferriatus as the research object,the developmental stages of Charybdis ferriatus were divided into 7 stages:T1,T2,T3,T4,T5,T6,and M stages for artificial seedling cultivation experiments.The results showed that①from the average stage survival rate of crab seedlings,the highest survival rate in autumn and spring was in the T1 stage,which was 100%;The lowest survival rate was at the stage of juvenile development,which was 42.5%;the second lowest survial rate was at the large eye larva stage,accounting for 51.1%.During the breeding process of Charybdis pumila,the T6 stage metamorphosis to the large eye larva and the large eye larva metamorphocis to the I stage juvenile crab were the most important stages.②The overall survival rate of the crab seedlings from the rust spotted crab to the T3 stage in spring and autumn was 48.1%,the overall survival rate of the T6 stage metamorphosis to the large eye larvae stage was 11.4%,and the overall survival rate of the seedlings that eventually developed into the I stage juvenile crab was 5.0%.
