To promote utilization of Okinotorishima island and its surrounding areas mainly in the fishery field, fishery resources and environmental conditions were surveyed in and around the coral reef of the island. Corals were widely distributed in the lagoon. Some useful fishery species were caught through the wide range from the surface to the deep water around the reef. Their preys such as eggs, juveniles and young of some small sized fish species were also observed there. Therefore, it may be possible to utilize the island as a good fishing ground with an artificially increased primary production. To develop this potential, some ideas and their issues to be solved in the future were discussed in this study.
