| Abstract | As a baseline survey to clarify the structure and function of bacterial populations in the intertidal waters of the Yellow Sea near Kunsan in 1987/1988, annual variation of bacterial number and biovolume was estimated by AODC method. Rod-shaped bacteria were more than 74% of all cells during the investigation period. Average biovolume of sampled bacteria ranged from 3.19 ± 0.59×10^-2 to 6.19 ± 0.76×10^-2 ㎛^3 for coccoid bacteria, and from 4.57 ± 0.17×10^-2 to 12.94 ± 0.21×10^–2 ㎛^3 for rod-shaped ones. It showed that larger biovolume occurred at surface in case of coccoid bacteria, while at bottom in case of rod-shaped ones. There was little correlation between population density and biovolume. Diameters of edlls were below 0.5.mu.m among 77-89% of all measured coccoid bacteria, and lengthes of cells more than 70% of all measured rod-shaped ones were below 1㎛. It explains the high percentage of "mini-bacteria" was distributed in the investigation area. | ||
