Isolation and identification of <i style="">Vibrio</i> spp. in diseased <i style="">Channa punctatus</i> from aquaculture fish farm

Abstract

During the present study <i style="">Vibrio </i>spp. were isolated from infected <i style="">Channa punctatus</i> and physico-chemical properties were analyzed from various ponds. Among the twenty ponds under study, four were contaminated by agricultural wastewater. The microbial communities in all these ponds appeared to be dominated by <i>V. harveyi</i>, <i>V. parahaemolyticus</i>, <i>V. fischeri</i> and <i>V. cholerae</i>. Out of these <i>C. punctatus </i>was <i>mostly infected by V. cholerae, V. parahaemolyticus</i> and <i>V. harveyi</i>. It can be transmitted to all fishes and infect fishes of other ponds.
