Cultured seeds of the sea urchin were released and their dispersion examined. This area was abundant in seaweed, but its deeper bottom showed frequent movement of drift sand. For a few days after the release, the seeds migrated at a pace of below 1m/day and formed colonies on stable stone. The dispersion range was limited to within 20m for the first 6 months, but exceeded 30m one year after their release, and the longest record was found to be 75m during the second year. In group '84, not such a long-distance migration was found, but most of the individuals were concentrated in a specific area. It was assumed that migrateion and dispersion of seeds were affected strongly by waves via the topographical layout and sea bottom.
