摘　　要：本文旨在研究红尾皇冠的胚胎发育过程,以期为该鱼的规模化繁育及养殖技术的优化提供支持。对红尾皇冠受精卵进行连续观察,研究其胚胎发育过程。结果表明,红尾皇冠发育成熟的卵为端黄卵,呈卵圆形,淡黄色,具黏性,卵径在1.5 mm左右。在水温(30±0.5)℃水中孵化48 h可全部出膜,完成胚胎发育过程。研究认为红尾皇冠胚胎发育可分为受精卵阶段、卵裂期、囊胚期、原肠期、神经胚期、器官形成期、孵出期等7个阶段。In order to optimize large-scale breeding and cuhring for Green Terror （Aequideus rivulatus）, this paper studied on its embryonic development. The embryonic development of Green Terror （Aequideus rivulatus） was studied by continuous observation. The result showed that the mature eggs were telolecithal eggs, oval in shape, faint yellow, sticky, and 1.5 mm in diameter. It took 48 h from fertilization to hatching out under water temperature （30±0.5） ℃. It is concluded that the embryonic development process couhl be divided into 7 stages including fertilized egg stage, cell division stage, blastula stage, gastrula stage, neurula stage, organ formation stage and hatching stage.
