The sampling was made by vertical hauling of 0-50 m layer. The net was made of the bolting silk XX No.13, measuring 22.5 cm in mouth diameter. The catch was left standing in the laboratory, and the settling volume was measured. Since the proportion of diatom volume is far greater than that of other Plankton constituents, the seasonal change of settling volume of total plankton generally corresponds the change of diatom population. This is not the case in December and January, since in those months Noctiluca increased markedly, and the occurence of diatoms and other plankton forms occurred very sparely. In April, as the water temperature rised, Nitzschia seriata became extremely abundant, while very few of them were found in June. Largest growth of diatoms was observed in July and August, although the species were not so numerous. In October and November, when the water temperature was going down, the total quantity of plankton as well as diatoms became decreased, while the number of diatom species was found most abundantly in this season.}, pages = {113--118}, title = {鹿児島湾における珪藻類の季節的変化に就て}, volume = {4}, year = {} }
