ASSESSMENT OF PHYSICO-CHEMICAL PARAMETERS OF MADDUR AND KERETHONNUR LAKES IN MANDYA WITH RELATION TO ZOOPLANKTON DIVERSITY

Abstract

Mandya district in Karnataka is in Cauvery river basin. It is famous as sugar bowl of Karnataka and known for fishing also. Maddur and Kerethonnur are two important lakes present in Cauvery river basin and are the source of irrigation for many villages of the area. In Maddur and Kerethonnur lakes the physico-chemical parameters were analyzed from January 2021 to December 2021 on monthly basis for totally 12 months. Estimation of different physico-chemical parameters with relation to zooplankton diversity was done during the investigation period. Most of the parameters values were found within the WHO permissible limits. These values were found supporting the growth of zooplankton. Totally 14 protozoan species, 06 cladoceran species, 04 ostracod species, 04 copepod species and 10 species of rotifers were recorded during the study period.
