A. M. Mane and V. S. Kanvate

The present paper is prepared from the data collected during different seasons from June 2004 to May 2005. An attempt is made to enumerate the planktonic diversity of the Manar river Dist. Nanded. The result shows that the zooplanktonic diversity was lesser as compared to phytoplankton. Although highly polluted, the Manar river contains a considerable number of both phyto and zooplankton species. The plankton community showed seasonal variations. The phytoplankton community was consisting of members of Chlorophyceae, Myxophyeeae, Bacillariphyceae and Chlorophyceae were represented by species of Oedogonium, Volvox, Eudorina. Microcystis. Oscillatoria and Anabaena including certain diatoms. The zooplankton community was consisting of members of Cladocerans, Copepods, Ostracode and Rotifers and were represented by species of Daphnia, Moina, Cereodaphina, Cyclops, Cletocamptus. Brachionus Keratella, and Metapidia. The ecological significance of the plankton diversity and the seasonal variation in total plankton volume is discussed in the light of available literature.
