Population dynamics of Rotifers in Jannapura tank, Karnataka


Author(s): K Harish Kumar, BR Kiran

Abstract: In this study water quality status of Jannapura tank near Bhadravathi town of Shimoga district was assessed by rotifers analysis during January to December 2008. A total of 05 genera and 08 species of Rotifera belonging to 4 families were recorded. The family Brachionidae consists of 5 species and rest of the families consists of single species of rotifers respectively. The density of rotifers varied from 12 to 145 organisms/litre. The zooplankton analysis showed an average and lower abundance of species in rainy months and maximum occurrence in summer months due to the different environmental and inflow characteristics of the water body. Occurrence of rotiferan species indicates the water quality deterioration and onset of eutrophication in Jannapura tank. In the present study, as per water quality recommended by CPCB, Rawals data and BIS standards, the tank water is not suitable for human consumption and hence, the water body is eutrophic and productive.
