“To Study The Seasonal Variations In Ichthyofauna On Account Of Planktons Of Kolar Water Reservoir Bhopal”

Abstract

At Kolar Reservoir in Bhopal, Madhya Pradesh, India, research on phytoplankton, zooplankton, and ichthyol fauna was conducted. Cyanophycea, Bacillariophyceae, Chlorophyceae, and Euglenophyceae were the four groups that made up the phytoplankton community during the study period. Cyanophyceae was the dominant group among the four. During monsoon season, there was a noticeable quantity of phytoplankton. Five groups—Rotifera, Cladocera, Copepoda, Protozoa, and Ostracoda—represented the zooplankton. Twelve genera belonging to the appropriate orders represented the diversity of fish in the Kolar Reserve. Major carps, exotic carps, and other species were among them. The maximum fish diversity was discovered in the post-monsoon months of November and December. Based on the quantity of fish species, seasonal diversity indicators such as Palou’s evenness, Marg alef’s species richness, and Shannon-Wiener species diversity were derived to assess the health of Kolar reservoir's ecosystem. These investigations will support the preservation and management of the Kolar Reservoir's Ichthyofauna and other aquatic ecosystems.
