锯缘青蟹胚胎复眼发生的形态观察

采用光镜和电镜技术。观察了锯缘青蟹胚胎复眼发生的过程，并将之划分为4个阶段：复眼色素带出现期，复眼色素带斑状期，复眼色素带条状期和复眼色素带核仁期．刚孵出幼体的复眼呈黑色半球形，着生在粗短的眼柄原基上。小眼表面观呈六边形．复眼发生和胚胎颜色变化密切相关，复眼可作为评判锯缘青蟹胚胎发育阶段的重要指标，为其科学人工育苗提供指导．

The Development of the Compound Eyes of the Embryo in Scylla serrata

By optical microscopy and electron microscopy we studied the development of the compound eyes in Scylla serrata embryo,which could be divided into 4 phases according to morphological characters:1-Eps appear phase:a pair of orange thin ribbon lacy Eps appeared near the outiside of optic lobe.2-Eps speck phase:the Eps enlarged to be red small ellipse.3-Eps oblong phase:the Eps lengthened to be brown oblong,the dividing lines of ommatidia appeared.4-Eps ellipsoid phase: the Eps rapidly widened and fully developed to be black large globosity,the limit of ommatidia became clear and radiate.In addition,the dark half-ball-like compound eye of Zoea I,which fixed at the stubby eyestalk rudiment,was composed by plenty of hexagon-like ommatidia.It showed that the development of the compound eyes was correspond with the change of the embryo color.The compound eye could be an important index for embryogensis,which would provide inspection and forecast for the embryonic development in the breeding activity.
