摘  要：
使用激光扫描共聚焦显微镜对鹰爪虾与中国对虾雌虾纳精囊的形态结构进行研究。结果表明，鹰爪虾与中国对虾都具有封闭式纳精囊。鹰爪虾纳精囊表面被前后两片甲壳板所覆盖，两板中间为一开口，交配后被胶体物质所堵塞。纳精囊中部为单一的囊腔，囊腔向后部两侧延伸形成两个袋状的囊，为贮存精子囊的部位。中国对虾纳精囊内为单一的囊腔，外面覆盖有两片半圆型、左右对称的甲壳质薄片。囊腔内部由前向后伸出三个锥状的甲壳质突起，交配的雌虾，锥状突起镶嵌于精荚内，有固定精荚的作用。

摘  要：
The morphology and structure of thelycum and sperm storage in Penaeus chinensis and Trachypenaeus curvirostris were studied using laser scanning confocal microscope. They all have closed thelycum. The thelycum of T.Curvirostris is covered with fore and aft two carapace slices, between the slices in center aperture, which is usually stoppered by jelly substance after male. At the center of thelycum is one single cavity and there are two sack like vesicle at rear end of thelycum in which sperm sacs are stored. The thelycum of P.chinensis has single cavity covered with two semi round, right left symmetry carapace slices. There are three tapers shaped prominences stick out from front into the cavity. In maled female Chinese shrimp, the prominences were mosaicked into spermatophore, which could firm the spermatophore.
