Abstract

In this study, moribund salema (Sarpa salpa) individuals from a public aquarium were investigated to identify the cause of disease. A minor scale loss and partial skin depigmentation were observed in the diseased fish. Internal investigation of fish revealed hyperemia in the liver and the intestines and haemorrhages in the muscle tissues. When the histopathological sections of tissues were examined, it was determined that the bacterial infection affected especially the gill epithelium, the intestinal mucosa, the heart muscle and hemopoietic tissues of the spleen. According to phenotypic and biochemical characteristics as well as SSU rRNA sequencing results, the isolated bacteria was Vibrio harveyi and consistently seen all the examined samples of visceral organs including kidney, spleen, liver and blood. However, Vibrio vulnificus and Pseudoalteromonas piscicida bacteria were also isolated from blood and spleen tissues of one sick fish among others.
