%X The bottle method with the daily exposition is a reliable tool for determining the total primary production in eutrophic water bodies, if the biomass of phytoplankton does not exceed 15.0 g/m3. The implementation of this method with the daily exposition at a higher biomass of phytoplankton introduces errors into the measurements. At higher biomass parameters of phytoplankton (more than 15.0 g/m3), the values of the total primary production are 1.74-2.78 times lower than the integral values obtained by summing the data of 4-hour exposures, The data obtained are statistically valid.
