Phytoplankton play a vital role in carbon sequestration and are essential for maintaining the overall balance and biodiversity of freshwater environments. Phytoplankton is crucial for managing lake health, monitoring eutrophication, and supporting aquatic biodiversity. Phytoplanktons are the chief primary producers and are of prime importance in aquatic ecosystem as the productivity of aquatic ecosystem is totally dependent on these. They form the basic link of food chain for all aquatic organism. The diversity of phytoplankton components in the aquatic ecosystem serves as a reliable index for monitoring a water body. We examined the phytoplankton diversity in Kotdam, which is situated 40 km. away from Jhunjhunun (Rajasthan). It is also popularly known as Sarju Sagar Bandh. Samples were collected monthly from Aug.2022 to Jan.2024. Different Species of phytoplankton related to the member of three algal groups, namely Chlorophyceae (greens) Cyanophyceae (blue greens) and Bacillariophyceae (diatoms) were observed. The species Cladophora, Crucigenia, Microspora, Chara, Spiyogyra (5greens), Navicula, Nitzschia, Synedra, Diatoma, Coscinodiscus (5diotoms) Spirulina, Nostoc, Anabaena, Oscillatoria (4 blue greens) were recorded from the village Kotdam. Climate of local environment factors are likely to have major impact on phytoplankton diversity of fresh water.
