摘要： 应用光镜技术和透射电镜技术,研究了日本沼虾胚胎复眼的发生.在原肠期,胚区前端的外胚层细胞增殖形成视叶原基.发育至后无节幼体期开始形成视神经节.在前蚤状幼体早期胚胎出现复眼色素，同时构成复眼的细胞开始分化。前蚤状幼体晚期，复眼色素区扩大到复眼直径的一半。复眼由个眼构成，每个个眼由角膜、角膜生成细胞、晶锥、小网膜细胞等组成。超微结构显示，胚胎的复眼结构与成体的相似，但感杆束直径比成体小。至胚胎孵化，眼柄尚未发育完善。

Abstract: We studied the development of the compound eyes in Macrobrachium nipponense by histological section methods and electron microscopy.The results showed:At gastrula stage, the cells in front of the embryonic area graduslly cleave to form optic disc rudiment.When the embryo reaches egg-metanauplius stage,the optic ganglion bigins to form. At egg-protozoea stage,the pigment begins to appear. The structure of the compound eyes at egg-zoea stage is similar to the adult,which including lentigen,lentigen cell,crystalline cell, retirular cell and rhabdom.

Key words: embryonic development, opic disc rudiment, compound eyes, Macrobrachium nipponense, embryonic development, opic disc rudiment, compound eyes
