Piscine Orthoreovirus-1 Isolates Differ in Their Ability to Induce Heart and Skeletal Muscle Inflammation in Atlantic Salmon (Salmo salar)

Pathogens, 2020
Piscine orthoreovirus 1 (PRV-1) is the causative agent of heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon (Salmo salar). The virus is widespread in Atlantic salmon and was present in Norway long before the first description of ...

First Strike: Description of the Events at the First Salmon Farm Affected by the 2025 Algal Bloom in Northern Norway

Journal of Fish Diseases, EarlyView.
ABSTRACT Harmful algal blooms (HABs) are a threat to fish welfare, occurring suddenly and unexpectedly causing significant consequences for fish and salmon farmers worldwide. Norwegian farmers have been facing this challenge at irregular intervals since the very beginning of the industry. This report describes the events on the first fish farm affected

Vaccination Reduces Shedding of Salmonid Alphavirus Subtype 3, but Bacterial Co‐Infection Influences the Effect

Journal of Fish Diseases, EarlyView.
ABSTRACT Waterborne horizontal transmission of viral diseases in fish relies on the release of infectious virus particles (termed shedding) into the aquatic environment. Both the rate and duration of shedding are critical for efficient viral spread, making interventions that reduce shedding valuable for disease control.

Dynamics of Polarized Macrophages and Activated CD8+ Cells in Heart Tissue of Atlantic Salmon Infected With Piscine Orthoreovirus-1

Frontiers in Immunology, 2021
Piscine orthoreovirus (PRV-1) infection causes heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon (Salmo salar). The virus is also associated with focal melanized changes in white skeletal muscle where PRV-1 infection of macrophages ...

Global Warming Affects the Pathogenesis of Important Fish Diseases in European Aquaculture

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
The effect of global warming on pathogens and their fish hosts that could exacerbate the negative outcomes for aquaculture. Changes in farming practices and the development of innovative mitigation tools may prove essential to cope with the effects and impacts of rising water temperatures on fish diseases in Europe.

Mapping Hatchery Risk Factors for Mortality in Post‐Smolts: A Qualitative Study

Aquaculture Research, Volume 2026, Issue 1, 2026.
The transition from hatchery to sea is a crucial stage in Atlantic salmon aquaculture. The initial post‐transfer phase is challenged with high mortality rates. This vulnerable phase not only impacts farm productivity but also raises significant concerns for fish welfare and industry sustainability.

Piscine Orthoreovirus from Western North America Is Transmissible to Atlantic Salmon and Sockeye Salmon but Fails to Cause Heart and Skeletal Muscle Inflammation. [PDF]

PLoS ONE, 2016
Heart and skeletal muscle inflammation (HSMI) is a significant and often fatal disease of cultured Atlantic salmon in Norway. The consistent presence of Piscine orthoreovirus (PRV) in HSMI diseased fish along with the correlation of viral load and ...
