Studies on the disease infestation of fish pathogen isolated from fishes Trichogaster fasciatus (Bloch.), Channa punctatus (Bloch.) and Esomus danricus (Ham.) collected from a stream water in R.S. Pura Jammu was conducted. Inoculum taken from the skin, gills and intestines indicated the presence of a variety of aquatic bacteria. A total of twenty-two isolates were identified phenotypically, of which fifteen isolates were found to be pathogenic. Percentage incidence of different pathogens i.e., Salmonella spp. was 53.3%, followed by 26.66% of Escherichia coli, 13.33% of Pseudomonas spp. (causing skin lesions) & 6.66% of Proteus vulgaris (causing Red Spot disease) in Channa puctatus and Trichogaster fasciatus respectively. Of the three fishes investigated, percental occurrence of pathogenic infection was significantly higher (P<0.005) in Channa punctatus. However, Trichogaster fasciatus shows the presence of only Proteus vulgaris infection.
