ABSTRACT
Rajsamand Lake, a significant waterbody in Rajasthan, India, plays a crucial role in regional water management and supports diverse aquatic life. Rajsamand Lake primarily has freshwater. This study investigates the diversity and distribution of zooplankton in the surface waters of Rajsamand Lake. Standardized sampling methods were employed, including vertical and horizontal hauls with plankton net, to ensure comprehensive coverage of the lake’s surface strata. The Zooplankton diversityin aquatic ecosystem depends on the limnological characteristics of the water. The zooplankton species belongs to order Cladocera, Copepods andAnastroca.Apercentage composition consists of 13.7% Copepod among the zooplankton diversity. Copepods diversity reaches its peak during March, April and May and its diversityreduces during October, November and December. Copepods are crucial in aquatic ecosystems as primary consumers of phytoplankton, supporting the food chain by serving as prey for many fish and other marine organisms. Their role in nutrient cycling and their abundance across diverse aquatic environments highlight their ecological dominance. Economically, they are vital for fisheries and aquaculture due to their importance as a food source and live feed. Scientifically, copepods are used to study climate change impacts, biodiversity, and developmental biology, underscoring their ultimate significance and widespread influence. The findings highlight the dynamic nature ofzooplankton communities in Rajsamand Lake and underscore the influence of environmental factors on their distribution.
