A tentative survey on selected marine fish farms was undertaken to delineate the extent to which infections with Staphylococcus species occur in Turkish aquaculture systems. To determine the presence and the distribution of fish pathogenic staphylococci, representative farm types such as marine cages as well as inland pond farms working with saline‐ground water and a large hatchery were selected. Field sampling was performed in a total of 13 commercial fish farms that are located in the most‐popular aquaculture sites of Turkey. Samples were taken between October 2013 and August 2014. Almost all size classes of the most commonly marine cultured fish species in Turkey were investigated, including Dicentrarchus labrax , Sparus aurata , Argyrosomus regius , Diplodus puntazzo , Dentex dentex , Onchorhynchus mykiss and Salmo labrax . After a visual check, specimens with various clinical signs were sampled for bacteriological and histopathological investigations. Mixed infections of staphylococci along with Vibrio and Aeromonas representatives were detected in Dicentrarchus labrax , Sparus aurata and Diplodus puntazzo samples obtained from 7 farms. The following pathogens were identified: Staphylococcus. epidermidis , S. aureus , S. capitis subsp. capitis , S. lentus , S. hominis subsp. hominis and S. sciuri subsp. sciuri . Main clinical and histopathological effects of the infections in fishes were revealed. The pathogenicity of some isolates was confirmed with in vivo pathogenicity assay and SDS‐PAGE analysis.
