| Outline of Final Research Achievements |
Teleost egg is covered with a thick envelope called chorion, and has a micropyle at animal pole through which sperm access to the egg plasma membrane. The present study elucidated the egg-sperm interaction being consisted of activation of sperm motility by an ovarian fluid coupled with sperm guiding into micropyle by a protein factor. Such fertilization system is suggested to be common in many teleost species.
