Outline of Final Research Achievements

Egg survey database with lunar age data was constructed on Japanese sardine, Japanese anchovy, chub mackerel and Pacific saury. Existence of lunar cycle was examined by the analyses of periodicity models on the spawning record of each species. In case of the Pacific saury, lunar cycle of spawning behavior was significantly observed, but it were not proved in other species.
