%X 为了系统观察并描述尖吻鲈胚胎发育及其各时期特征，试验采用人工注射催产的方法获得尖吻鲈受精卵，然后使用体视显微镜进行拍照、观察，描述各个发育阶段的特征。研究发现，在水温为(29 ± 1)℃的孵化条件下，尖吻鲈受精卵历时15 h 50 min孵化出膜，82 h鳔形成。胚胎发育过程及孵化后发育经历了受精卵阶段、卵裂阶段、囊胚阶段、原肠胚阶段、神经胚阶段、器官形成阶段、孵化出膜阶段和胚后发育8个阶段，共分为32个时期。尖吻鲈与硬骨鱼类发育特征基本相同，不同的是尾牙期和眼囊形成期几乎同时进行。该实验详细描述了热带海水经济鱼类——尖吻鲈的胚胎发育过程，为提高和优化海水鱼类人工繁育和养殖技术提供重要的理论依据。<br />
In order to systematically observe and describe the embryonic development and characteristics of various stages of barramundi, artificial fertilization method was used to obtain the fertilized eggs, and then observe by a stereo microscope, and the characteristics of each development stage were described. Incubation at a water temperature of (29 ± 1)？C, the fertilized egg of barramundi hatched for 15 h and 50 min, and swim bladder formed at 82 h. The embryonic development pro-cess is divided into eight stages: fertilized egg, cleavage stage, blastocyst stage, gastrula stage, neu-roblast stage and organogenesis stage and post-hatching development. The eight stages are divided into 32 periods. This experiment described the embryonic development process of tropical marine economic fish-barramundi in detail, and provided an important theoretical basis for improving and optimizing the artificial breeding and breeding technology of marine fish.
