Piscine reovirus ( PRV) in wild Atlantic salmon, Salmo salar L., and sea‐trout, Salmo trutta L., in Norway
Abstract This is the first comprehensive study on the occurrence and distribution of piscine reovirus ( PRV ) in Atlantic salmon, Salmo salar L., caught in Norwegian rivers. PRV is a newly discovered reovirus associated with heart and skeletal muscle inflammation ( HSMI ), a serious and commercially...

PRV was detected in Atlantic salmon from all counties included in the study and in 31 of 36 examined rivers. PRV was also detected in sea‐trout but not in anadromous Arctic char. In this study, the mean proportion of PRV positives was 13.4% in wild Atlantic salmon, 24.0% in salmon released for stock enhancement purposes and 55.2% in escaped farmed salmon. Histopathological examination of hearts from 21 PRV ‐positive wild and one cultivated salmon (Ct values ranging from 17.0 to 39.8) revealed no HSMI ‐related lesions. Thus, it seems that PRV is widespread in Atlantic salmon returning to Norwegian rivers, and that the virus can be present in high titres without causing lesions traditionally associated with HSMI .
