Abstract:

Water quality and population dynamics of planktonic rotifers were investigated in relation to spatiotemporal changes in a natural pond. Pond was divided into three parts. Sampling was carried out monthly from April, 2012 to September, 2012. In this research work fifty eight rotifer species of 11 families and 20 genera were identified. The Highest density of rotifer population (127±34.5 ind/ml) was noted in June and lowest (89.3±29.9 ind/ml) in April. Brachionus calyciflorus was the dominant species with mean density 33.34±8.57 ind/ml. Testudinella patina had lowest (0.33±0.33 ind/ml) mean population density and were present only in April. Diversity of rotifers was negatively correlated with dissolved oxygen and transparency. However, positive correlation was noted with total dissolved solids, temperature, pH, conductivity, and total hardness. The Shannon–Weaver and Simpson diversity indices specified that Aroop pond had excessive diversity of rotifer species throughout the study period.
