Seasonal fluctuations of bacterial numbers were surveyed at four points in the Minoh River and the ma River between 1989-1990 for 18 months. The ratio of the colony forming unit to the total direct count (CFU/TDC) was the minimum at oligotrophic points, while it tended to high values at eutrophic points. It was corre-sponded with the saprobity of environment. It was suggested that the CFU/TDC ratio is useful as the parameter of the environmental evaluation.
