Pigment diversity and biomass of phytoplankton in lentic water bodies of Bhadravathi taluk, Karnataka-India

Abstract

The present investigation revealed that biomass of phytoplankton by chlorophyll estimation method shows that Chl.a, Chl.b and Chl.c distributions were unequal. The minimum concentration of Chl.a was 0.112mg/L during November at BVTS3 and maximum .077 mg/L was recorded same station in the month of December. The Chl.b concentration was 0.0023mg/L minimum during October at BVTS1 and maximum 0.6118mg/L during August at BVTS3 and 0.0083 mg/L Chl.c was minimum during October at BVTS3 and maximum 3.894 in October at BVTS4.The correlation coefficient of six physico-chemical parameters show fluctuating the positive and negative correlation with different chlorophyll pigments.  The Chl.c shows positive correlation with magnesium but others not. In BVTS1 of Chl.a, b and c show positive correlation with water temperature, pH bicarbonate and other stations were not showed the positive correlation.
