Pathogens From Salmon Aquaculture in Relation to Conservation of Wild Pacific Salmon in Canada: An Alternative Perspective

Aquaculture, Fish and Fisheries, Volume 5, Issue 4, August 2025.
ABSTRACT Several articles over the last two decades have provided data, analyses and interpretations that suggest there are significant impacts of pathogens transmitted from farmed salmon on wild Pacific salmon populations in British Columbia (BC), the westernmost province of Canada.

Antiviral Responses and Biological Concequences of Piscine orthoreovirus Infection in Salmonid Erythrocytes

Frontiers in Immunology, 2019
Salmonid red blood cells are the main target cells for Piscine orthoreovirus (PRV). Three genotypes of PRV (PRV-1,2,3) infect Atlantic salmon (Salmo salar), Chinook salmon (Onchorhynchus tshawytscha), Coho salmon (Oncorhynchus kisutch), rainbow trout ...

Pathogen and Gene Expression Profiles of Atlantic Salmon From an Endangered Population

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 4, April 2025.
ABSTRACT The role of pathogens in impacting the behaviour and fate of salmonids has been studied extensively for some selected pathogens such as sea lice. However, the whole pathobiome of the fish are seldom considered and may confound and influence the study species in situ.

The Pathobiome of Salmo trutta From the North Sea to the Barents Sea

Journal of Biogeography, Volume 52, Issue 3, Page 558-570, March 2025.
ABSTRACT Aim Salmonids are some of the best studied species with respect to their pathobiome, and at the northern range limit, there is potential for pathogens to expand with both climate change and increased fish farming in the north. Location We sampled sea‐run brown trout from throughout Norway for gill tissue and conducted both pooled and ...

Erythroid Progenitor Cells in Atlantic Salmon (Salmo salar) May Be Persistently and Productively Infected with Piscine Orthoreovirus (PRV)

Viruses, 2019
Piscine orthoreovirus (PRV-1) can cause heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon (Salmo salar). The virus targets erythrocytes in the acute peak phase, followed by cardiomyocytes, before the infection subsides into ...

Biosafety in Norwegian Aquaculture—Risks and Measures in RAS Facilities and Well‐Boats

Reviews in Aquaculture, Volume 17, Issue 1, January 2025.
ABSTRACT Biosafety is a central concern in Norwegian salmon farming, as diseases and parasites are common. Continued production depends on preventing and controlling diseases and parasites. A critical part of the farmed salmon's life is during smolt production and the following well‐boat transport out to sea. Biosafety here is thus essential, and there

Piscine orthoreovirus subtype 3 (PRV-3) causes heart inflammation in rainbow trout (Oncorhynchus mykiss)

Veterinary Research, 2019
Piscine orthoreovirus (PRV) mediated diseases have emerged throughout salmonid aquaculture. Three PRV subtypes are currently reported as causative agents of or in association with diseases in different salmonid species.

Stochastic Static Model Updating of Bridge Using Homotopy Method and Pre‐Estimated Solution Domain

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
When implementing structural model updating, whether the model is stochastic or deterministic, the ill‐posed issue is a challenging problem. To effectively address this problem, this paper proposes a new static stochastic model updating method, which combines the homotopy method with the pre‐estimation technique of solution domains of the updating ...

Genetic variation of Piscine orthoreovirus and the presence of HSMI in farmed Atlantic salmon from Arctic Norway

, 2021
Piscine orthoreovirus-1 (PRV1) is ubiquitous throughout the world and can cause heart- and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon (Salmo salar). HSMI was first diagnosed in Norway in 1999. The virus is highly prevalent among farmed salmon in Norway, but the pathogen doesn’t always induce HSMI.

Introduction and temporospatial tracing of piscine orthoreovirus‐1 (PRV‐1) in Norwegian farmed Atlantic salmon (Salmo salar) after local fallowing

Journal of Fish Diseases, Volume 47, Issue 9, September 2024.
Abstract Piscine orthoreovirus‐1 (PRV‐1) is a prevalent agent in Atlantic salmon (Salmo salar) and the causative agent of heart and skeletal muscle inflammation (HSMI), an important disease in farmed Atlantic salmon. Investigations into the introduction and dissemination routes of PRV‐1 in a field setting have been limited.
