Infectious pancreatic necrosis (IPN), viral hemorrhagic septicemia (VHS) and infectious hematopoietic necrosis (IHN) are the most significant viral diseases of salmonid species. This study examined the seroprevalence ofinfectious pancreatic necrosis virus (IPNV), viral hemorrhagic septicemia virus (VHSV) and infectious hematopoieticnecrosis virus (IHNV) in rainbow trout cultured in Turkey. A total of 597 serum samples of adult trout were obtainedfrom 18 commercial trout farms in the Middle and Eastern Black Sea regions of Turkey and were then examined by thevirus neutralization test. As a result of the test, VHSV and IHNV antibodies were not detected. However, IPNV antibodies were found in 11 of 18 trout farms (61.1%) and 45 of 597 serum samples (7.5%). Three viral agents characterized ascausing persistent infections were serologically screened for the first time in Turkey. The high seropositivity rate againstIPNV was namely caused by asymptomatic carrier broodstock fish.
