Susceptibility of arctic char (Salvelinus alpinus) to infectious hematopoietic necrosis virsus (IHNV) and infectious pancreatic necrosis virus (IPNV)

These viruses can infect various life stages of salmonid and, in the case of IPNV, nonsalmonid fishes, and fish that survive primary infection can be lifelong virus carriers. Both IHNV and IPNV can be readily transmitted between generations and among contemporary generations.

Empirical observations and experimental evidence indicate that species susceptibility is greatest in brook trout, followed respectively by rainbow trout, brown trout, lake trout, and Atlantic salmon.
