Abstract
The present study investigates the seasonal fluctuation of
physico-chemical parameters and their correlation with zooplankton density in
Virla reservoir, West Nimar (Khargone), during 2022–2023. Zooplankton, as
primary consumers, play a crucial role in aquatic food webs and serve as
bioindicators of water quality. A total of 24 species belonging to five groups
were recorded: Rotifera (8 species), Cladocera (5 species), Protozoa (4
species), Copepoda (4 species), and Ostracoda (3 species). Rotifera dominated
the community, followed by Cladocera, Protozoa, Copepoda, and Ostracoda.
Seasonal variations revealed maximum zooplankton density in summer and minimum
in rainy seasons, correlating with fluctuations in temperature, pH, dissolved
oxygen (DO), and nutrient availability. The study highlights the ecological
significance of zooplankton diversity and emphasizes the need for biodiversity
conservation in freshwater ecosystems.
