Immunohistochemical detection of piscine reovirus (PRV) in hearts of Atlantic salmon coincide with the course of heart and skeletal muscle inflammation (HSMI) [PDF]

, 2012
Aquaculture is the fastest growing food production sector in the world. However, the increased production has been accompanied by the emergence of infectious diseases. Heart and skeletal muscle inflammation (HSMI) is one example of an emerging disease in

Cellular heterogeneity in red and melanized focal muscle changes in farmed Atlantic salmon (Salmo salar) visualized by spatial transcriptomics [PDF]

, 2023
Spatial transcriptomics is a technique that provides insight into gene expression profiles in tissue sections while retaining structural information. We have employed this method to study the pathological conditions related to red and melanized focal ...

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 ...

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 ...

Field surveillance has revealed a high prevalence of PRV-3 in clinically healthy salmonids in Italy

Aquaculture Reports
Piscine orthoreovirus genotype 3 (PRV-3) has been reported in several European countries, and in Italy it was detected only once in 2017 without any associated disease outbreak.

Viral Protein Kinetics of Piscine Orthoreovirus Infection in Atlantic Salmon Blood Cells

Viruses, 2017
Piscine orthoreovirus (PRV) is ubiquitous in farmed Atlantic salmon (Salmo salar) and the cause of heart and skeletal muscle inflammation. Erythrocytes are important target cells for PRV. We have investigated the kinetics of PRV infection in salmon blood

Fish Sludge as Feed in Circular Bioproduction: Overview of Biological and Chemical Hazards in Fish Sludge and Their Potential Fate via Ingestion by Invertebrates

Reviews in Aquaculture, Volume 17, Issue 1, January 2025.
This review provides knowledge of the biosecurity risks of using fish sludge to produce novel feed ingredients from low‐trophic, extractive animal species in circular value chains. The review includes nutritional composition, sludge treatment practices, EU regulations, and the fate of microbial and chemical hazards contained in sludge till raw ...

Deciphering the pathogenesis of melanized focal changes in the white skeletal muscle of farmed Atlantic salmon (Salmo salar)

Journal of Fish Diseases, Volume 47, Issue 10, October 2024.
Abstract Melanized focal changes (MFCs) in the fillet of farmed Atlantic salmon is a major quality concern. The changes are thought to initially appear as acute red focal changes (RFCs) that progress into chronic MFCs. Recent findings have indicated that hypoxia may be important in their development, possibly leading to necrosis affecting not only ...

Additional file 3 of Genetic grouping and geographic distribution of Piscine orthoreovirus-1 (PRV-1) in farmed Atlantic salmon in Norway

, 2021
Additional file 3: Phylogenetic tree constructed from partial sequences of S1 (bp 77–1021) using Maximum Likelihood (ML). The analysis included 37 field isolates (black) and six reference isolates of known virulence (high virulent in red, low virulent in green). Bootstrap values were calculated from 1000 replicates.

Examination of brown trout decline in the pre-alpine Isar river [PDF]

, 2020
A decline of brown trout (Salmo trutta fario) was observed in the pre-alpine river Isar over the last years. The Bavarian Fisheries Association and local recreational anglers reported high mortalities especially within the warmer summer months.
