This study was conducted to investigate Serratia liquefaciens infection in juvenile cultured rainbow trout (Oncorhynchus mykiss Walbaum) during June and July in 1996 about 20 days after flooding in three farms in Erzurum. Bacterial isolates were identified from each farm and tested to determine sensitivity against 18 chemotherapeutants. In addition to minimum bactericidal concentrations (MBC) of chloramine-T and potassium permanganate (KmnO4) were exposures of 17.07-20 mg/l for 1 h and 23.27 mg/l for 10 min.
