Summary Discovery of the environmental triggers for the initiation of sperm motility (Movisawa and Suzuki, 1980) was one of the starting points for understanding the mechanisms regulating sperm behaviour, activation and chemotaxis, which occur as a prologue to fertilization. Further discoveries on egg-derived factors triggering the activation of sperm motility in Pacific herring (Movisawa et al., 1992; Yanagimachi et al., 1992) also demonstrated the cooperation of two different proteins playing an important role for the successful encounter of sperm and egg at fertilization. The purpose of this paper was to review the details of the cell-signaling factors for the initiation and activation of sperm motility in teleosts. An additional aim was to introduce the conceptual idea of regulatory mechanisms for sperm motility reflecting evolutionary processes as well as strategies for establishing successful fertilization mechanisms in teleosts.
