Phytoplankton Distribution and Algal indices of Mid Manair Dam in Rajanna Siricilla District, Telangana

Algae are an integral component of the food chain in aquatic ecosystems, playing a significant role in shaping the population dynamics of zooplankton and other aquatic animals. Algae, as photoautotrophs, have the ability to synthesize energy and serve as the primary food source for many tiny aquatic organisms. Lakes are vital water reservoirs that serve many functions. This study is specifically focused on the variety of algae. The current study was conducted from January 2021 to December 2022. The Mid Manair Dam serves as the primary water supply for the nearby villages, providing drinking water as well as supporting agricultural activities and fish farming. The current study aims to determine the variety of phytoplankton genera. The assessment of water's appropriateness for irrigation and drinking purposes relies significantly on the variety of phytoplankton. The water samples were kept in a solution of 4% formalin and examined using a binocular microscope to identify the presence of algae. There are primarily four distinct types of freshwater algae that have been documented in Mid Manair Dam. The organisms were classified as Chlorophyceae, Bacillariophyceae, Cyanophyceae and Euglenophyceae the lake water is widely used for potable water and agricultural irrigation.
