ASSESSMENT OF ZOOPLANKTON DIVERSITY OF NEW CONSTRUCTED RESERVOIR BISNOOR PACHDHAR RESERVOIR IN DISTRICT, BETUL, MP

The status of healthiness of any freshwater ecosystem is basically depends on the diversity and density of zooplankton inhabiting the freshwater resources. Zooplanktons are considered as fundamental source for primary consumer in any aquatic environment. Which influence greatest scope in decisive the total productivity of freshwater body. The present study is attempted to the qualitative and quantitative distribution of zooplankton in different sites of Bisnoor Pachdhar reservoir. The study was carried out seasonally from July 2020 to June 2021. The whole assessment was divided into four major seasons viz monsoon, post monsoon, winter and summer. The compilation of the zooplankton samples and their qualitative and quantitative was through followed the standard procedures of limnological analysis. During the study period sequence of dominant groups Rotifera > Copepoda > Protozoa > Cladocera > Ostracoda was observed at dam site and mid site of all season. On another hand at tail end site major dominant group was Copepoda > Protozoa > Cladocera > Rotifera > Ostracoda noted during monsoon, post monsoon and winter and during summer the order of dominant group Copepoda > Rotifera > Protozoa > Ostracoda > Cladocera was recorded in Bisnoor Pachdhar reservoir.
