What causes Infectious Salmon Anaemia and which species are affected?

Infectious Salmon Anaemia is caused by Infectious Salmon Anaemia Virus (ISAV), an orthomyxovirus in the genus Isavirus within the Orthomyxoviridae family. It is a virus, not a bacterium or a prion, and not a herpesvirus. The disease mainly affects salmonids, especially farmed Atlantic salmon and rainbow trout, though other salmonid species can be susceptible. The essential idea is that ISA is a viral infection of salmonids caused by ISAV, an orthomyxovirus.
