ROTIFERS - POLLUTION OR PRODUCTIVITY INDICATORS

In order to test whether rotifers are most efficient as pollution or p roductivity indicators, impact of abiotic parameters and primary produ ctivity on abundance of rotifers was studied. Population of rotifers w as found to be more in polluted zone with numerical superiority of Bra chionus rubens and Brachionus angularis. Different inter-correlations were estimated and from multiple regression analysis it was observed t hat rotifers were influenced most by chloride, which is an index of po llution.
