摘要：The present communication highlights the seasonal abundance and fluctuations trends of planktonic population of River Beas in relation to its physico-chemical parameters. Plankton plays an important role for maintaining the productivity of the water body. Plankton refers to microscopic aquatic plant having little or no resistant to water current and living free floating and suspended in open or pelagic water. Present investigation revealed the presence of Bacillariophyceae, Chlorophyceae, Rodophyceae and Cyanophyceae among phytoplankton groups and Copepods followed by Rotifers, Protozoans, and Cladocerans among Zooplankton. A total of 26 phytoplankton genera were encountered with most dominant being Closteridium, Schroederia, Ulothrix, Closteriopsis, Gomphonema and Batrachospermum. Maximum population of phytoplankton was observed during winter season where as minimum was observed in rainy season.
