ABSTRACT
The present work fulfilled its task as a direction finder in a diversified subject area, embodying both theoretical and applied knowledge. It contributed to a more informed evaluation and response to environment problems in water quality, pollution control and environmental concerns; comprising a logical scientific approach to which there is no known competitor. In the present study the main focus on the objectives like quarterly variation in physio-chemical properties of water, Primary Productivity in terms of Biomass and Chlorophyll content, variations in Composition and Density of zooplankton population and correlation between BOD & COD with zooplankton Population of BARALI LAKE, Hurda. The zooplankton found on the water body and float with the water current but they plays important part in transferring the energy from one to another trophic level, they act as a food alternative for many aquatic creatures. They are main vital part of eutrophication. Zooplankton are found as tremendous Bio indicator to estimate the contamination of water body. The biodiversity of zooplankton are found very high in the potentiality as bio indicator their diversity and density depends on certain environmental factors like temperature, pH, pollution, stratification etc. and also on some biological factors like predation, food restrictions and competition for survival. There are four main classes of zooplankton viz. Rotifera, Ostracoda, Cladocera and Copepoda. The zooplankton community especially rotifers changes with respect to change in biotic and abiotic factors like temperature, pH, turbidity, BOD, COD, Alkalinity, TDS, dissolved oxygen, Total hardness etc.
