Abstract;The purpose of this study was to grasp the actual egg-laying situations in coast underwater forests of herrings, which came and were caught, and to clarify environment suitable for egg-laying. The authors grasped the distribution and mode of life of seaweeds constituting coast underwater forests, and tried to develop a multiplication technology and form egg-laying fields. They conducted visual observation at a place of Mashike town, 4 places of Rumoi City and 6 places of Kodaira town during March and May 2000. As a result, they recognized the adhesion of eggs of herrings at 3 underwater forests in Rumoi City. The submarine topography in an underwater forest seems to influence the visiting route of herrings for egg-laying. The following are described on the coast in Rumoi City: Distribution of kelps, Sargassum, and Phyllospadix iwatensis; conditions of wave height, flow velocity, and water temperature; growth and maturation of Sargassum confusum and Cystoseira hakodatensis.
