Quantitative and qualitative analyses of bacterial flora associated with fresh water containing
microbial pathogens present on the skin, gills, and fins of polycultured healthy common carp
Clarias batrachus. Physico-chemical and biological parameters of Wardha and Wainganga river
water were investigated and it was found that, during winter season these two river water has low
alkalinity and low chloride concentration. The temperature was also found to be a fluctuating
parameter. During winter season maximum affected fishes were reported. Pathogenic bacteria and
fungi were also reported during these months in these water bodies. In the present study Clarias
batrachus showed its presence throughout the year except the summer months in Wardha and
Wainganga river water confirming their involvement in the initial process of damage, similarly the
presence of fungi Saprolegnia parasitica, and Aspergillus sp. isolates from Wardha and Wainganga
riverwater.
