Received: 10 January 2020; Revised: 24 January 2020; Accepted: 30 January 2020 Abstract: Present study was aimed to assess the zooplankton diversity and entire ecological condition of Sarangpani pond of Bhopal city. Total of 78 zooplankton species were recorded from the ponds waters during two years of study period which consisted of Rotifera 29 species (37%), Cladocera &Protozoa 16 species each (20% each), Copepoda 13 species (17%) and Ostracoda 4 species (5%). Among all the zooplankton classes, species belongs to the class Rotifera were recorded their dominance during both the years of study. The dominance of Rotifers population in terms of quality has been recorded. Seasonal variation of zooplankton population recorded maximum species diversity of class Rotifera during summer (1st year) and winter season (2nd year). On the other hand, minimum population density was contributed by class Copepoda in all the season. Presence of various pollution indicator zooplankton species indicates and evidences the high anthropogenic pressure and direct mixing sewage from the nearby catchment in the pond waters which has accelerated the eutrophication in the Sarangpani pond.

INTRODUCTION Zooplankton provides the main food for fishes and can be used as indicators of the trophic status of water body1,2,. They provide an important link between trophic status and water quality of the aquatic ecosystems. Being a vital and important biological component of the aquatic ecosystem, zooplankton are able to reflects any environmental changes which helps us to monitor the entire ecological conditions of aquatic ecosystem. Changes in the zooplankton species composition have been used as indication of increased eutrophication of fresh waters3. Zooplankton are not only useful as bio-indicators to help us detect pollution load, but are also helpful for ameliorating polluted waters. They assume a great ecological significance in aquatic ecosystem as they play vital role in food web, nutrient recycling, and in transfer of organic matter from primary producers to secondary consumers like fishes4. Hence, zooplankton communities, based on their quality and species diversity, are used for assessing the productivity vis -a‐ vis fishery resource, fertility and health status of the ecosystem5. Generally, species composition and community structure of zooplankton in a water body is found to be fairly constant and cannot be changed for many decades, but it changes when water body is under stress pollution or eutrophication. Therefore, during the assessment of the ecological status of water bodies the species composition, quantitative characteristics of individual species and groups of zooplankton is of great importance6,7. Bhopal district has numerous aquatic resources supporting rich biodiversity. Among all the water bodies, only few references are available on the planktonic biodiversity of Sarangpani pond. Therefore, an attempt has been made to investigate the composition of the zooplankton community in Sarangpani pond during 2007-2008.The present study on planktonic fauna of Sarangpani pond will be helpful for researcher for further studies. MATERIAL AND METHODS Study Area: Sarangpani pond is also called as Piplani Pond as it is situated in the Piplani area of BHEL city of Bhopal and lies between Latitude 23º12'13.23" N and Longitude 77°25'18.31"E at an elevation of 1601ft. This is mainly used for fish culture. Due to mixing of organically enriched effluents from catchment the quality of water body has degraded. Few Dhobi Ghats are established along periphery of the pond. Apart from this, large quantities of domestic wastes from surroundings are also added into the pond. Most of the time the pond is covered with Eichornia crassipes and green algal blooms mainly composed of Cyanobacteria. For the present study a single sampling site was selected at the central point of the pond, close to floating fountain. Some important morphometric features of the Sarangpani pond were estimated and documented during present study which is given in Table 1 and the location of the pond is shown in Fig. 1. 54 J. Chem.

For identification of zooplankton species up to the species level for their taxonomic and various morphometric characters the concentrated samples were examined under the inverted microscope (Metzer made) following the available standard taxonomic references8-16. 55 J.
