This study aimed to screen bacterial disease in cultured horse mackerel in the marine fish farm of the Southern Black Sea Region of Turkey. Fish bacteria were surveyed monthly and collected in November 2011 to October 2013 from cultured horse mackerel in the sea-cages. During the study, no parasite was found while several Gram negative bacterial species including Aeromonas hydrophila, Chryseobacterium indologenes, Vibrio vulnificus, Bulkholderia cepacia, Photobacterium damselae damselae and Vibrio alginolyticus were isolated from cultured fish. Fifty percent or more of the bacteria were resistant to streptomycin, sulfamethoxazole, gentamycin, cephalothin, and ampicillin. The most effective antibiotics were florefenicol and chloramphenicol. The most prevalent resistance genes were found to be beta-lactam (blaTEM-OT3-4) and Tetracycline (tetB).
