采用组织学方法 ,研究了中国对虾循环系统的发生过程 ,在无节幼体第 3期 ,起源于头胸甲皱褶部位的腹侧中胚层细胞通过增殖向背面迁移 ,在中肠的背面形成一中胚层板 ,此板两侧向背面上卷、合拢而成心脏 ;与此同时 ,该中胚层板两侧周围的中胚层细胞向两侧迁移 ,与体壁接触形成围心腔 ;心孔出现在无节幼体第 5期 ,是由该处的心壁细胞直接内陷形成 ;心脏的形态结构随着幼体的发育而不断完善 ,至蚤状幼体第 1期以后 ,组成心壁的细胞分化为单层的心肌细胞 ,随后其外包被一层由结缔组织细胞形成的心外膜 ;至仔虾期 ,心脏的外形和结构已与成虾的相似 ;背腹动脉发生的方式与时间和心脏的相同 ;中背动脉的发生包括两部分 :心脏近端的中背动脉由心脏前端延伸而成 ,心脏远端的中背动脉则由幼体前端背部中胚层细胞形成 ;血细胞最早出现在无节幼体第 1期。
