本文通过观察生活在尖紫蛤外套胺中的隐匿豆蟹性腺周年发育情况和分析头胸甲宽组成变化，研究隐匿豆蟹的繁殖和世代交替．隐匿豆蟹的繁殖期为３～１０月，繁殖盛期在４月下旬至６月上旬和９月下旬至１０月上旬两个繁殖高峰．隐匿豆蟹的世代交替是：在繁殖期早出生的个体，至翌年繁殖，形成第一个繁殖高峰．其中部分个体抱卵孵化后，性腺再次成熟和繁殖，这两部分豆蟹在繁殖后的当年死亡．因此这些个体，越过冬季，寿命只有１周年多．而在繁殖期晚出生的个体，翌年只繁殖一次，再过一个冬季，至第３年繁殖期再次繁殖后而死亡．这些个体越过两个冬季，寿命两周年．隐匿豆蟹生长至甲宽３．２ｍｍ后，才进入尖紫蛤外套腔中生活，在这以前，隐匿豆蟹营自由生活
In this paper, we observed the development of gonadal cryptogenesis in the exocarp of Actinidia crimsonum and analyzed the changes in the composition of the breasted croaker. Hidden beans and crabs breeding season for 3 to 10 months, the breeding peak in late April to early June and late September to early October two breeding peak. The generation of hidden crabs and crabs alternates between: the individuals born early in the breeding season will breed the following year, forming the first breeding peak. Some of them hatch after hatching, gonads mature and reproduce again, the two parts of the crab in the year after the death of breeding. Therefore, these individuals, over the winter, life expectancy is only more than one anniversary. However, individuals born late in the breeding season will only breed the following year, and then die again after a winter, breeding once again in the third year of their breeding season. These individuals crossed the two winter months, the second anniversary of their lives. Hidden beans and crabs grow to a width of 3.2mm, before entering the purple clam shell cavity life, before this, hide bean crab camp free life
