| Abstract: | Parallel determinations of phytoplankton biomass and chlorophyll-α concentration were carried out on five reservoirs. Highly significant positive correlations between phytoplankton biomass values and chlorophyll-α values were found. The possibility of finding a conversion factor linking these two parameters is discussed. The chlorophyll content per unit phytoplankton biomass encountered during the period of study in all reservoirs varied between 0.14 and 3.41% of fresh weight. The influence of light intensity, nutrient concentration and species composition on chlorophyll content per unit phytoplankton biomass is considered. |
