In the present study, the role of zooplankton in monitoring the health of aquatic ecosystem has been reviewed. The present study revealed that the zooplankton community exhibit notable monthly fluctuation depending on water quality and seasonal variation. The winter months shows comparatively significant diversities. zooplankton serves as a regional bioindicator of lake eutrophication. The soil-water chemistry, food chain, alkalinity, DO, pH, DO and nutritional status of the water body affect the diversity and density of zooplankton. Rotifers are a type of zooplankton that reacts more quickly to environmental changes and uses.
