Collections were made in May, August and November, 1969 using the Kitahara's quantitative net (20cm in diameter and stretched with bolting silk net XX No. 13) from the bottom to the sea surface. According to the results of these observations settling volume of plankton organisms varies from 0.9cc/m^3 to 77.5cc/m^3 and shows a high productivity in August and November. Eighty-seven species of plankton Copepods and seventy-five species of Diatoms have been identified during these observations. In quantity, Diatom is the most important group, especially, Thalassiothrix frauenferdii, Thalassionema nitzschioides and Skeletonema costatum which dominate throughout the year. Total number of Diatom cells vary from 2000 to 6000 per litre. The zooplankton communities were represented by Oithona nana with Paracalanus parvus ; or by Oithona similis and Oncaea media in the inner part of the bay, and Paracalanus parvus with Calocalanus pavo, Calocalanus styliremis etc. in the outer part of the bay. Copepods varies from 100 to 4000 in number per cubic metre.}, pages = {113--134}, title = {志布志湾に於けるプランクトンの季節的変化について}, volume = {19}, year = {1970} }
