The population of bacteria in the Sea of Harima was measured with a hydrophobic grid membrane filter and the changes of population of bacteria were compared with those of Chattonella sp.The following results were obtained.The change of population of bacteria which were able to assimilate the extracellular products of Chattonella antiqua depended on that of Chattonella sp. (spindle form type).The change of population of bacteria which were able to assimilate glycorate depended on that of Chattonella sp. (globular form type).The population of aerobic and facultative anaerobic heterotrophic bacteria could be related to the sum of populations of Chattonella sp. (globular form type) and that of Chattonella sp. (spindle form type).Bacteria which were able to utilize extracellular products of phytoplankton were estimated as aerobic and facultative anaerobic heterotrophic bacteria. But the population of bacteria which were able to assimilate the extracellular products of C. anriqua did not correlate to the turbidity as a measure of the total amount of phytoplankton.
