An infection with a high mortality rate was observed in fry weighing between 5-25 g in 10 different rainbow trout (Oncorhynchus mykiss Walbaum, 1792) farms in the Kahramanmaraş province. Liver, spleen, kidney, intestinal, and skin tissue samples were obtained from fish exhibiting symptoms of the disease and subsequently cultured on both general and special media. These samples were then incubated in an incubator at temperatures ranging from 15 to 24°C for a period of 24 to 72 hours. Subsequent biochemical identification tests were performed on pure strains obtained from these samples taken from trout farms, as well as 94 biochemical tests for the identification of Gram-negative and Gram-positive bacteria at the species level on The Biolog GEN III MicroPlate plates. The identification process yielded the detection of 10 strains of Vibrio aestuarianus, and subsequent antibiogram analysis was conducted.
