The present paper deals with the Zooplankton composition, seasonal fluctuation and diversity indicies in river Narmada, Hoshangabad from Nov. 2010-Oct. 2012. The Zooplankton composition of river Narmada at three sampling stations were composed of 38 species belonging to 5 groups viz. Rotifer, Cladocera, Copepod, Protozoa and Ostracoda. The Zoolankton community was dominated by Rotifers (40%) followed by cladocera (29%), copepoda (18%), protozoa (8%) and ostracoda (5%). Several types of indices such as dominance index (simpson, 1949) varied from 0.94 to 0.96 while shannon’s diversity index 3.18 to 3.46 and dominance -D varied from 0.04 to 0.06 of river Narmada were calculated. The dominance of Brachionus indicates the level of organic matter in the river.
