Zooplankton are indeed tiny, microscopic aquatic animals that play a crucial role in freshwater ecosystems as a vital link in the food web and contribute significantly to the overall productivity of these environments. They are performing at second trophic level in energy flow and switch over to conversion of detritus matter into edible animal food. The present study deal with the study of Zooplankton diversity and seasonal variation in Raviryala Pedda Cheruvu was conducted to check the status in the area and provide new insights into its ecology. The study was carried out during the period of two years i.e. June- 2022 to May- 2024. A total of 40 species were found in this reservoir. Among these, rotifers comprise of 20 species, Cladocera 07, Copepods 07, Ostracoda 2 and Protozoa 2. The season wise zooplankton analysis showed that the number of population was highest during winter (post monsoon), followed by summer (pre-monsoon) and lowest during rainy season (monsoon)

Raviryala Pedda Cheruvu, Zooplanktons, seasonal diversity

Zooplankton diversity and abundance of this lake showed significant seasonal variations, with influenced by environmental factors like temperature, rainfall, and food availability. In this lake zooplankton populations were more diverse and abundant during post-monsoon, due to more favorable for growth and reproduction, and less diverse during rainy seasons due to dilution and other factors. Different zooplankton groups, above mentioned such as rotifers, cladocerans, and copepods, may exhibit varying responses to seasonal changes. Rotifers, were often abundant in eutrophic (nutrient-rich) waters and it showed that water quality indicaters. Monitoring zooplankton diversity and abundance of this lake clearly provided valuable insights into the impacts of climate change and other environmental factors on aquatic ecosystems. Scope of this study: The scope of zooplankton diversity in a lake ecosystem is broad and reflects the complex interplay between various biotic and abiotic factors. Understanding this diversity is essential for assessing the health of the lake and managing its resources sustainably. Ecosystem Management: Understanding zooplankton diversity helps in managing water quality, controlling harmful algal blooms, and maintaining a healthy aquatic ecosystem. Conservation Efforts: Knowing which species are present and how they respond to environmental changes is essential for developing targeted conservation strategies. Resource Management: By monitoring zooplankton, we can gain insights into the overall health of the lake and manage its resources sustainably
