Distribution of infectious pancreatic necrosis virus (IPNV) in wild marine fish from Scottish waters with respect to clinically infected aquaculture sites producing Atlantic salmon, Salmo salar L.
Abstract This study represents the first large‐scale investigation of IPNV in Scottish wild marine fish. Kidney samples were taken from 30 627 fish comprising 37 species and 45 isolations were made from nine different species, illustrating these as reservoirs of IPNV in Scottish waters. The estimate...

Titres of 3.8 × 10 2 PFU g −1 and 2.8 × 10 1 PFU g −1 were calculated from common dab, Limanda limanda (L.), and saithe, respectively.
