Abstract
The present study deal with the role of biotic parameter especially zooplankton community and its trophic level to assess water quality of Murna river, Shahdol district (M.P.), India. The zooplankton of the river Murna was studied from July 2022 to June 2023 at different sampling stations. Four sampling station were selected for the study, station -A (Kalyanpur), station- B (MPEB Colony), station – C (Sohagpur) and station – D (Kshirsagar). Physico-chemical parameters like Temperature, pH, Dissolve oxygen, Biological oxygen demand and Chemical oxygen demand were also measured and the correlation coefficient value of temperature with zooplankton showed significant relation (0.075), and inverse relation with pH, Dissolve oxygen, Biological oxygen demand and Chemical oxygen demand (-0.022, -0.685, -0.477 & -0.569), it was found that they influence zooplankton abundance in river Murna. During the study period various species of Rotifers, Copepods, Cladocerans were recorded, in all samples total 18 species of zooplankton identified, 10 species of Rotifers, 05 species of Cladocerans and 03 species of Copepods. The zooplankton community was dominated by Rotifers, in all samples. The highest zooplankton densities were recorded in the month of May and June.
