Abstract
Upper Lake (Bhoj Tal or Bada talab) is a man-made reservoir. The water body of Upper lake receives domestic discharge which leads a large amount of nutrient inputs and the highest amount of nitrate and phosphate indicates that water is eutrophic in nature. The present study has been carried out to study seasonal abundance of certain zooplankton in Upper lake, Bhopal. The abundance of zooplankton was studied in pre-monsoon, monsoon and post monsoon season. In the present study zooplanktons comprised of total 5 taxonomic groups: Protozoa, Ostracoda, Rotifera, Cladocera and Copepoda. The greater abundance of zooplankton was recorded during summer season while the lowest abundance was recorded during the monsoon season.
