To evaluate plankton diversity in relation to physico-chemical parameters of the Yamuna river, the present study was conducted from March 2019 to February 2020. Three sites along the Yamuna River were chosen for regular sampling: Delhi (B1), Mathura (B2) and Agra (B3). 11 species of phytoplankton and 9 species of zooplankton were recorded from site B1 with a concentration of 15,517 individual L-1. At site B2 14 species of phytoplankton and 5 species of zooplankton with a concentration of 15,329 individual L-1 was observed. At site B3 a total 15 species of phytoplankton and 5 species of zooplankton were recorded with a concentration of 19,453 individual L-1. The highest abundance of group Cynophyceae in phytoplankton and Rotifera in zooplankton was observed during the study period at sites B1, B2 and B3. Physico-chemical parameters were found suitable for plankton growth at site B3.
