摘要
本文以人工催产、自然受精获得的鲂受精卵为材料，用胰蛋白酶脱去卵膜，将裸卵置于Ｈｏｌｔｆｒｅｔｅｒ氏液和曝气的蒸馏水中培育，在解剖镜下仔细观察鲂的胚胎发育特征，并将其胚胎发育划分为８个阶段、２９个时期.旨在为鲂的人工繁育提供基础资料。
The embryonic development of Megalobrama skolkovii was studied from 1989 - 1990. The fertilized eggs of Megalobrama skolkovii were obtained by artificial spawning and natural insemination. They were treated in trypsase solution in order to remove the egg membrane, then the naked eggs were cultured consequently in Holtfreter solution and aerated distilled water, 29 develop- ment stage characteristics were described and illustrated.
