| Abstract: | 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. |

| Keywords: | Megalobrama skolkovii embryonic development naked eggs |
