| Outline of Final Research Achievements |
Both thread-sail filefish and black scraper learned the self-feeding within a short period. They showed clear diurnal feeding pattern synchronizing with a given photo period and the light-dark period defined to be a main external environmental factor which controlled the self-feeding activity of these two species. The optical fiber sensor for the filefish which did not receive the effect of marine wind and wave was developed, and filefish successfully accessed it and activated the self-feeder. Self-feeding system equipped with the optical fiber sensor was installed on the floating sea-cage and reared black scraper filefish. The feeding quantity received the effect of water temperature, however, continuous self-feeding activity was confirmed throughout a year. Thus, the self-feeding technique with the optical fiber sensor was confirmed to be a potential feeding technology for filefish culture.
