Abstract
The focus of this study is on the diversity of phytoplankton and the physical and chemical characteristics of the Narmada River during the post monsoon season. In the morning, water samples were collected and phytoplankton were collected using a plankton net with a mesh size of 20 µm. A total of forty-three different genera of phytoplankton were identified in the study area, belonging to four main classes: Chlorophyceae, Bacillariophyceae, Cyanophyceae, and Euglenophyceae. The study also analyzed various physico-chemical parameters, including temperature, pH, dissolved oxygen, carbon dioxide, alkalinity, calcium content, water hardness, nitrate and silicate levels, and productivity. The results revealed significant variations in phytoplankton diversity and physico-chemical parameters across different study sites.
