Seasonal Dynamics of Some Zooplanktons in Two Fresh Water Ponds

Dr. B. Sai Ram Pattnaik

Abstract :

The interaction between various groups of zooplanktons is a major feature in the productivity of ponds. The seasonal abundance of one group imparts influence on the other. The success of one group results in the failure or limitation of another group, in other words one group paves way for the other. In fresh water ponds there may institute several groups of macro plankton fauna but very few can only dominate. With the coming up of summer when the temperature begins to raise, there starts a drop in the abundance of Copepods as well as Cladocerans paving way for the Rotifers to dominate the show. With the onset of rainy season, again the Copepods start dominating over both Rotifers and Cladocerans. Within the same group of zooplanktons again one genus dominates over the other for certain periods and found either in small numbers or become dormant during other periods. In present study the seasonal disparity of distribution, succession, abundance and species diversity of some zooplanktons especially that of Rotifer fauna in relation to the physico, chemical and biological factors is carried out.
