The limnological study is prerequisite for the sustainability of any aquatic environment. The aim of the study was to know the physico-chemical parameters and qualitative, quantitative abundance of plankton. Dhepa River was selected for the purpose of the study. Fortnightly data were collected from three sampling sites from May to December 2014. Nine physico-chemical parameters were measured following standard methods. Plankton was collected through filtration technique. A total of 52 plankton were identified which belongs to five phytoplankton and three zooplankton groups. Chlorophyceae and Rotifera were the dominant groups in all phytoplankton and zooplankton groups, respectively. The physico-chemical parameters were within the suitable and productive ranges. So, government of Bangladesh should take different management approaches to keep the riverine ecosystem pollution free and sustainable for capture fisheries.
