The Pathobiome of <span><i>Salmo trutta</i></span> From the North Sea to the Barents Sea Open
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 …

Nanopore sequencing provides snapshots of the genetic variation within salmonid alphavirus-3 (SAV3) during an ongoing infection in Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) Open
Frequent RNA virus mutations raise concerns about evolving virulent variants. The purpose of this study was to investigate genetic variation in salmonid alphavirus-3 (SAV3) over the course of an experimental infection in Atlantic salmon an…

Most of the escaped farmed salmon entering a river during a 5‐year period were infected with one or more viruses Open
Disease interactions between farmed and wild populations have been poorly documented for most aquaculture species, in part due to the complexities to study this. Here, we tested 567 farmed Atlantic salmon escapees, captured in a Norwegian …

Regional and temporal variation in escape history of Norwegian farmed Atlantic salmon Open
Each year thousands of farmed Atlantic salmon escape from seawater net pens, and introgression has been documented in a range of wild populations. Due to greater experience in the wild, escapees that have been on the run for a longer perio…
View article: Occurrence of salmonid alphavirus and piscine orthoreovirus‐1 infections in migrating salmon (<i>Salmo salar</i> L.) post‐smolt in western Norway
Occurrence of salmonid alphavirus and piscine orthoreovirus‐1 infections in migrating salmon (<i>Salmo salar</i> L.) post‐smolt in western Norway Open
Viral diseases are a serious problem in Atlantic salmon ( Salmo salar L.) farming in Norway, often leading to reduced fish welfare and increased mortality. Disease outbreaks in salmon farms may lead to spread of viruses to the surrounding …
View article: Experimental transmission of piscine orthoreovirus-1 (PRV-1) in different life stages of Atlantic salmon (Salmo salar) and brown trout (Salmo trutta)
Experimental transmission of piscine orthoreovirus-1 (PRV-1) in different life stages of Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) Open
Piscine orthoreovirus -1 (PRV-1) causes the disease heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon, and the virus has been detected in wild anadromous Atlantic salmon and brown trout. However, the infection prevale…

Co-diversification of an intestinal <i>Mycoplasma</i> and its salmonid host Open
Understanding the evolutionary relationships between a host and its intestinal resident bacteria can transform how we understand adaptive phenotypic traits. The interplay between hosts and their resident bacteria inevitably affects the int…

Wild Atlantic salmon enter aquaculture sea‐cages: A case study Open
There are more than 3,000 Atlantic salmon aquaculture sea‐cages distributed along the coastline of Norway. Many of these sea‐cages are located along the migration routes of wild Atlantic salmon ( Salmo salar ) postsmolts. This study docume…

Wild salmonids are running the gauntlet of pathogens and climate as fish farms expand northwards Open
Salmon farming has multiplied from a side business of coastal farmers to one of the world's major aquaculture species. This has dramatically altered the disease dynamics between farmed and wild salmonids. As salmon fish farming has increas…
View article: Prevalence and genotypes of infectious salmon anaemia virus (ISAV) in returning wild Atlantic salmon (<i>Salmo salar</i> L.) in northern Norway
Prevalence and genotypes of infectious salmon anaemia virus (ISAV) in returning wild Atlantic salmon (<i>Salmo salar</i> L.) in northern Norway Open
Infectious salmon anaemia (ISA) is a serious viral disease of Atlantic salmon (Salmo salar L.). The ISA virus (ISAV) occurs both as apparently avirulent ISAV-HPR0 variants with full length of haemagglutinin–esterase (HE) gene including the…

Annual report on health monitoring of wild anadromous salmonids in Norway 2018 - Screening of migrating Atlantic salmon (Salmo salar) postsmolts from the Trondheim fjord for viral infections Open
Very few virus infections found in migrating postsmolts from the Trondheim Fjord\nCommissioned by the Norwegian Food Safety Authority, the Institute of Marine Research has studied the occurrence of several potential disease-causing viruses…
View article: Prevalence of piscine orthoreovirus and salmonid alphavirus in sea‐caught returning adult Atlantic salmon (<i>Salmo salar</i> L.) in northern Norway
Prevalence of piscine orthoreovirus and salmonid alphavirus in sea‐caught returning adult Atlantic salmon (<i>Salmo salar</i> L.) in northern Norway Open
Heart and skeletal muscle inflammation ( HSMI ) caused by piscine orthoreovirus ( PRV ) and pancreas disease ( PD ) caused by salmonid alphavirus ( SAV ) are among the most prevalent viral diseases of Atlantic salmon farmed in Norway. Ther…

The ecological profile of Atlantic salmon escapees entering a river throughout an entire season: diverse in escape history and genetic background, but frequently virus-infected Open
In 2014, 129 farmed salmon escapees captured in an upstream-migration trap located in the river Etne, western Norway, were investigated for viral infections, age at escape, size, and genetic composition. The frequency of escapees positive …

Genetic screening of farmed Atlantic salmon escapees demonstrates that triploid fish display reduced migration to freshwater Open
Each year, hundreds of thousands of farmed Atlantic salmon escape from fish farms into the wild. Some of these escapees enter freshwater, and manage to interbreed with native populations. To hinder further genetic introgression in native p…
