In this study, we considered how releasing red spotted grouper seedings have worked and how artificial reefs contribute with their growth at the coast of Ehime Prefecture. Interrelationships in the amount of seedings, underwater observed information and catch statistics are investigated. Young and semi-adult tended to observe more often at the reef areas with total seedings increasing, and the grown-sized were caught at some years later. In summer, breeding colored individuals were also confirmed. Accordingly, it is suggested that the role of artificial reefs is not only their early shelter, but also growing and breeding sites, all life cycle bases.
