Abstract

This study was carried out to reveal bacterial contamination and antibiotic resistance profiles of isolated bacteria in the hatchery systems of trout farms located in the Eastern Black Sea region of Turkey. Inlet water, egg, alevin and fry samples of 11 different trout farms were examined in terms of bacterial contamination in four different basins. After sampling, isolated bacteria were identified by making phenotypic and genotypic analyses. The majority of a total of 43 strains belongs to the genera Aeromonas and Pseudomonas, but also Lelliottia sp., Bacillus sp. and Lactococcus lactis were isolated from hatchery systems. Considering all basins, except for the 2nd basin, the highest antibiotic resistance of bacteria was against Ampicillin. The lowest antibiotic resistance percentages were determined against gentamicin and enrofloxacin. As a result of the research, the detection of different bacteria in the samples taken from the inlet water of fish farms showed presence of different bacteria contaminating the hatchery water. It thereby stressed the need for improved hygiene measures in these farms
