Source-derived summary

Infectious salmon anemia (ISA) is a viral disease of Atlantic salmon (Salmo salar) caused by infectious salmon anemia virus. It affects fish farms in Canada, Norway, Scotland and Chile, causing severe losses to infected farms. ISA has been a World Organisation for Animal Health notifiable disease since 1990. In the EU, it is classified as a non-exotic disease, and is monitored by the European Community Reference Laboratory for Fish Diseases.

Virology

ISA is caused by the infectious salmon anemia virus (ISAV). ISAV, a segmented RNA virus that is the only species in the genus Isavirus, which is in the family Orthomyxoviridae, and therefore related to the influenza viruses.

The genome encodes at least 10 proteins.

There are several distinct strains of the virus. The most common are a European strain and a North American strain.

Pathology

ISA virus causes severe anemia in infected fish.

Editorial summary

This brief starts where responsible research should: with the source description of “Infectious salmon anemia virus” as species of virus. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current lead gives the account dated anchors—1990—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Infectious, salmon and anemia can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the science & nature register because the source frames it as species of virus. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jun 10, 2026. The linked authority identifier is Q547421. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1990.

Critical limits

A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
