| Outline of Final Research Achievements |
The reproductive cycle of an aplacophoran mollusc, Scutopus schanderi (Mollusca: Caudofoveata) in western Wakasa Bay, the Sea of Japan was studied to establish a basis for studies of the development which has remained unclear. Observation of the gonad from the specimens collected monthly for consecutive 12 months revealed that the spawning appears to take place between late September and early October. Spawning in the laboratory was successfully induced for a few individuals collected before spawning in September by stimuli of UV treated sea water, Serotonin-Creatinine Sulfate, and the sperm, although the protocol needs to be further optimized.
