Abstract

Freshwater reservoirs in India are increasingly exposed to anthropogenic pressures, such as agricultural runoff, domestic sewage discharge, and water level fluctuations, which significantly influence nutrient dynamics and aquatic ecosystem stability. Biomonitoring using plankton communities provides an effective approach for evaluating ecological health, as these organisms respond rapidly to changes in physico-chemical conditions. The present investigation was carried out to assess the environmental status and trophic condition of Manar Reservoir, located near Barul village in Nanded district, Maharashtra, through zooplankton-based biomonitoring integrated with selected water quality parameters. Four sampling stations representing distinct hydrological zones from the river inflow region to the main storage area of the reservoir were selected for systematic study. Water and Zooplankton samples were collected twice monthly from January to December 2024. Physico-chemical parameters including temperature, pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), phosphate, sulphate, and nitrite–nitrogen were analyzed using standard methods. Zooplankton were collected using a standard plankton net, preserved when required, and identified under a research microscope based on morphological characteristics. The results indicated that the analyzed physico-chemical parameters remained within permissible limits throughout the study period, reflecting favorable environmental conditions. Seasonal variation was observed in Zooplankton diversity and abundance, with comparatively higher productivity during winter months. The absence of excessive organic and chemical pollution suggests that the reservoir is relatively free from significant ecological stress. Overall, the study demonstrates that Manar Reservoir maintains a stable Zooplankton community and good water quality. The findings provide valuable baseline data for long-term ecological monitoring and contribute to the sustainable management of this important freshwater resource.
