摘　　要：采用光镜技术对哲罗鱼、大麻哈鱼、怀头鲇、鲇卵黄吸收方式及器官形成进行比较。结果表明:哲罗鱼与大麻哈鱼卵黄吸收方式相同,都是通过血液循环及早期消化管进行吸收;怀头鲇与鲇卵黄吸收方式相同,是通过血液循环进行吸收的,但二者吸收位置有所不同;哲罗鱼与大麻哈鱼卵黄吸收较慢,大约60～70d卵黄被完全吸收;怀头鲇与鲇卵黄吸收较快,约在3～4d被完全吸收。4种鱼类卵黄吸收依照先卵黄球、后脂肪的顺序被吸收。探讨了卵黄吸收与器官发育的关系。The ways of yolk absorption and process of organofaction in Hucho taimen,Oncorhyn- chus keta, Silurus soldatovi and Silurus asotus were studied using the microscope technology. The results showed that the yolks of both H. taimen and O. keta were absorbed by the blood circulation and the early digestive tract. In S. soldatovi and S. asotus,the yolk was also absorbed by the blood circulation, but the location of absorption was different. About 60-70 days were needed for the yolks of H. tairnen and O. ke- ta to be completely absorbed. The yolks of S. soldatovi and S. asotus were absorbed faster, and the yolks were completely absorbed about 3-4 days. Of the four fish species, the yolk-sphere was absorbed first, and then the fat was absorbed. The relationship between yolk absorption and organ development were discussed.
