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
Madhun, Abdullah Sami; Wennevik, Vidar; Karlsbakk, Egil; Skaala, Øystein; Fiksdal, Ingrid Uglenes; Meier, Sonnich; Tang, Yongkai; Glover, Kevin (Peer reviewed; Journal article, 2017-05)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 ... -
Genetic screening of farmed Atlantic salmon escapees demonstrates that triploid fish display reduced migration to freshwater
Glover, Kevin; Bos, J. B.; Urdal, Kurt; Madhun, Abdullah Sami; Sørvik, Anne Grete Eide; Unneland, Laila; Seliussen, Bjørghild Breistein; Skaala, Øystein; Skilbrei, Ove Tommy; Tang, Y.; Wennevik, Vidar (Peer reviewed; Journal article, 2016-05)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 ... -
Most of the escaped farmed salmon entering a river during a 5-year period were infected with one or more viruses
Madhun, Abdullah Sami; Karlsbakk, Egil Erlingsson; Skaala, Øystein; Solberg, Monica Favnebøe; Wennevik, Vidar; Harvey, Alison C.; Meier, Sonnich; Andersen-Fjeldheim, Per Tommy; Andersen-Fjeldheim, Kaja Christine; Glover, Kevin Alan (Journal article; Peer reviewed, 2024)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 ... -
Occurrence of salmonid alphavirus and piscine orthoreovirus-1 infections in migrating salmon (Salmo salar L.) post-smolt in western Norway
Madhun, Abdullah Sami; Nilsen, Rune; Barlaup, Bjørn Torgeir; Karlsen, Ørjan; Karlsbakk, Egil Erlingsson (Journal article; Peer reviewed, 2023)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 ... -
Pandemic influenza vaccines - the challenges
Haaheim, Lars Reinhardt; Madhun, Abdullah Sami; Cox, Rebecca Jane (Peer reviewed; Journal article, 2009-12-03)Recent years’ enzootic spread of highly pathogenic H5N1 virus among poultry and the many lethal zoonoses in its wake has stimulated basic and applied pandemic vaccine research. The quest for an efficacious, affordable and ... -
Prevalence and genotypes of infectious salmon anaemia virus (ISAV) in returning wild Atlantic salmon (Salmo salar L.) in northern Norway
Madhun, Abdullah Sami; Mæhle, Stig; Wennevik, Vidar; Karlsbakk, Egil (Peer reviewed; Journal article, 2019-08) -
Prevalence of piscine orthoreovirus and salmonid alphavirus in sea-caught returning adult Atlantic salmon (Salmo salar L.) in northern Norway
Madhun, Abdullah Sami; Isachsen, Cecilie Helen; Omdal Strandenes, Linn Maren; Einen, Ann Cathrine B.; Mæhle, Stig; Wennevik, Vidar; Niemelä, Eero; Svåsand, Terje; Karlsbakk, Egil (Peer reviewed; Journal article, 2018-05)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 ...
