摘要：We have studied the rotifer community composition of Kullurchandai reservoir, a chief source for the nearby Virudhunagar town, during May 2007 to April 2008. Temperature, pH, dissolved oxygen, free carbon-di-oxide, alkalinity, chlorinity, salinity, total hardness, and phosphorus were measured simultaneously. We have identified 40 species of rotifers with various categories such as, eurythermal, stenothermal, alkalophilic and eutrophic indicators. Among these species, the genera Brachionus and Lecane were dominant in their presence. The physico-chemical parameters were recorded within the tolerance limit of rotifer species. The plenty of rotifer density was observed in February, 2008, while the lowest was recorded during August, 2007. The Diversity indices were recorded highest during February 2008 (1.9889) and lowest during October 2007 (1.1205) which showed a clear picture not only on the dynamics of the rotifer community but also on the nature of water body.
