Abstract :The present study investigated the bacteria present in the gills and intestines of three fish species (Chondrostoma regium, Capoeta trutta and Cyprinion macrostomum) obtained live from fishermen fishing in the Bingöl region of the Murat River. A total of 52 fish were sampled for analysis, with gill and intestinal tissues collected from each fish. Samples were diluted with Ringer\\\'s solution and cultured on Nutrient agar, Tryptic soy agar, Salmonella-Shigella agar, Baird-Parker agar, McConcey agar, GSP (Aeromonas and Pseudomonas selective) agar and Cytophaga agar. Bacterial identification was carried out using the application of straightforward and widely-utilised morphological analysis and biochemical tests within the field of microbiology. A total of 285 bacteria (117 from the gills and 168 from the intestines) belonging to 10 genera were isolated and identified. The most common bacterial species identified were Aeromonas hydrophila (12.63%), Corynebacterium sp. (1.05%), Enterobacter aerogenes (16.49%), Escherichia coli (35.40%), Cytophaga/Flexibacter. (4.21%), Proteus vulgaris (2.10%), Salmonella sp. (2.10%), Streptococcus sp. (8.77%), Staphylococcus sp. (14.22%) and Vibrio sp. (1.05%). It is very importance to carry out bacteriological examinations of fish living in all inland waters, as this provides valuable information on fish and human health, as well as offering information on water pollution through the bioindicator properties of bacteria.
