Outline of Final Research Achievements

The purpose of this study is to determine the spawning induced pheromone of bivalves, and to elucidate the endocrinological basis of synchronous behavior of their spawning. Analysis using multiple bivalve species suggested that a synchronous spawning system via spawning inducing pheromone may be a widely common mechanism for bivalves. We also attempted to isolate and purify substances possessing spawning-inducing activity using Mytilid bivalves.
