The chlorophyll a (Chl a) concentrations of three size-fractionated samples (0.2-2.0 µm, 2.0-25 µm, > 25 µm) were measured. Total Chl a concentrations varied from 0.72 to 105 µg l^<-1>. The average total Chl a concentrations in Osaka Bay was 6.41 µg l^<-1>, which was about seven times higher than that of Kii Channel (0. 87 µg l^<-1>). Moreover, the average contributions of the pico-, nano- and micro-phytoplankton to the total Chl a in Osaka Bay were 33%, 31% and 36%, respectively, but in Kii Channel were 62%, 27% and 11%, respectively. We concluded that phytoplankton community between Osaka Bay and Kii Channel differs according to size distribution.    This phytoplankton community in Osaka Bay and Kii Channel contained picoplankton with a maximum Chl a concentration of 6.0 µg l^<-1>, apparently higher than that of open ocean.
