Abstract: Primary production, biomasses and chlorophyll a level of size fractionated phytoplankton (<200 μm,<20 μm,<2 μm) were estimated in the water bodies (Botanical Garden, Children's Park, Malan River) with different nutrition. Water bodies in both Children's Garden and Malan River were found to be eutrophic lakes, dominated in green algae and diatom, respectively. In the case of Botanical Garden it was meso trophic lake, dominated in green algae. The contribution of algal picoplankton to biomasses and primary production decreased with the increasing of eutrophiction. The results showed that the planktonic algae less than 20μm in size were important in the biomasses and the production in the three water bodies. The ratio of the production of planktonic less than 20μm to the total production of phytoplankton was 53.7% in Botanical Garden, 57.2% in Children's Park and \{63.2%\} in Malan River. The comparison of the present results with others were carried out.
