ABSTRACT

Bhopal’s Upper Lake is not only the source of water but also the habitat of several aquatic life forms including variety of fish species. The present study aims to evaluate the BOD, E.coli and Pseudomonas spp. in shallow water of Bhopal’s upper lake at catchment areas sheltering some ornamental fishes on collective basis.Water samples were collected and ornamental fishes were observed from shallow water body of catchment area of the lake covering 4 sites near Boat club, Koh-e-Fiza, Karbala and Bairagarh region designated as S-1, S-2, S-3 and S-4 respectively. BOD, total microbial count, E.coli, and Pseudomonas spp. count were made in triplicates for 3 seasons. All the sites have highest BOD values in rainy season followed by summers then winters. Seasonal variation in occurrence of these fishes suggesting the increased and decreased presence in winter and rainy seasons respectively that could be correlated with microbial contamination and unsuitable aquatic environment for these fishes.
