Susceptibility of pike Esox lucius to viral hemorrhagic septicemia virus and infectious hematopoietic necrosis virus and potential transmission to rainbow trout Oncorhynchus mykiss

Determining the origin of recurrent outbreaks of fish diseases occurring on fish farms is essential to adapting disease prevention and control measures. In this study, we investigated the potential reservoir role of wild fish species living in the nearby aquatic environment of salmonid farms regularly found to be positive for viral hemorrhagic septicemia virus (VHSV). ). In addition to VHSV, infectious hematopoietic necrosis virus (IHNV) was also isolated from several pike Esox lucius samples collected from a pond near the salmonid farms of interest.
