Variations in Hydrobiological Characteristics of Atyal Pond in Gadhinglaj Tahsil, Dist. Kolhapur, Maharashtra

摘要

The paper describes physicochemical characteristics of Atyal pond (Tahsil Gadhinglaj, Dist. Kolhapur) of Maharashtra. Limnological studies were conducted during the October 2007 to September 2008. Variables analysed from surface water of the tank were temperature, transparency, pH, electrical conductivity, dissolved oxygen, alkalinity, hardness, chlorides, biochemical oxygen demand and primary productivity. It was observed that the water of Atyal pond is rich in nutrients, which shows that the pond has become eutrophic. The pond shows increased pollution level due to various activities taking place in and around the water body.
