Studies on Physico-Chemical Parameters and Biodiversity of Freshwater Algae in Kanbargi Lake of Belagavi (Karnataka)

Abstract

Abstract
Studies on biodiversity of phytoplankton in Kanbargi Lake records a total of 14 species belonging to four classes of algae which includes, Bacillariophyceae – 6 species, Chlorophyceae – 5 species, 2 species of Euglenophyceae and 1 species of Dinophyceae. Both qualitative and quantitative analysis revealed that Bacillariophyceae species were abundant. Algal pollution index revealed a score of 18 indicating that Kanbargi Lake is less organically polluted. A study on physico-chemical parameters of Kanbargi Lake revealed that pH ranged from 7.5 to 9.8, turbidity 0.3302 to 0.7112 m, electrical conductivity 840 to 1070 μS/cm, dissolved oxygen 5.5 to 10.8 mg/L, total hardness 230 to 270 mg/L, calcium hardness 85 to120 mg/L, total alkalinity 165 to 265 mg/L, temperature 21 to 25 °C, iron 0.3 to 1.0 mg/L, residual chlorine 0.0 to 0.2 mg/L, chloride 60 to 280 mg/L, ammonium 0.0 to 0.3 mg/L, phosphate 0.0 to 0.2 mg/L, nitrate 0.0 to 5 mg/L , nitrite 0.0 to 0.2 mg/L and fluoride 1.0 to 2.0 mg/L. Coli form test revealed presence of pathogenic bacteria. Based on the investigation it is concluded that Kanbargi Lake is less polluted but unfit for drinking.
