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
