Assessment of Water Quality for Aquaculture - A Case Study of Madhavara Lake in Bangalore

Periodical physicochemical analysis of Madhavara lake, a freshwater body, in Bangalore, was carried out from July, 2005 to June, 2006. Water quality for aquaculture was estimated with the parameters such as temperature, pH, conductivity, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), chlorides, hardness, nitrate, phosphate, sulphate and ammonical nitrogen. Results indicate severe deterioration of the water quality in this lake. The study suggests the water quality of Madhavara lake to be highly polluted, and hence, unfit for aquaculture.
