Caught in the trap: over half of the farmed Atlantic salmon removed from a wild spawning population in the period 2014−2018 were mature
Madhun, Abdullah Sami; Harvey, Alison C.; Skaala, Øystein; Wennevik, Vidar; Knutar, Sofie; Solberg, Monica Favnebøe; Quintela, Maria; Andersen-Fjeldheim, Per Tommy; Meier, Sonnich; Glover, Kevin Alan (Peer reviewed; Journal article, 2023)Whilst aquaculture continues its global expansion, containment of fish in sea cages remains a persistent environmental challenge. Within Atlantic salmon Salmo salar farming, widespread escapes over several decades have ... -
Co-diversification of an intestinal Mycoplasma and its salmonid host
Rasmussen, Jacob A.; Kiilerich, Pia; Madhun, Abdullah Sami; Waagbø, Rune; Lock, Erik Jan Robert; Madsen, Lise; Gilbert, Marcus Thomas Pius; Kristiansen, Karsten; Limborg, Morten T. (Peer reviewed; Journal article, 2023)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 ... -
Experimental transmission of piscine orthoreovirus-1 (PRV-1) in different life stages of Atlantic salmon (Salmo salar) and brown trout (Salmo trutta)
Kannimuthu, Dhamotharan; Roh, HyeongJin; Morton, Hugh Craig; Penaranda, Ma Michelle Demogina; Vossgård, Anne; Hansen, Tom Johnny; Fjelldal, Per Gunnar; Karlsbakk, Egil Erlingsson; Fiksdal, Ingrid Uglenes; Dahle, Maria; Berg-Rolness, Hakon Schau; Mæhle, Stig; Ghebretnsae, Dawit Berhe; Nordbø, Joachim; Patel, Sonal; Madhun, Abdullah Sami; Grove, Søren; Kvamme, Bjørn Olav (Peer reviewed; Journal article, 2023)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 ... -
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; Tang, Y.; Wennevik, Vidar (Journal article; Peer reviewed, 2016-02-09)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 ... -
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 (Peer reviewed; Journal article, 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 ... -
Potential disease interaction reinforced: double-virusinfected escaped farmed Atlantic salmon, Salmo salar L., recaptured in a nearby river
Madhun, Abdullah Sami; Karlsbakk, Egil; Isachsen, Cecilie Helen; Omdal, Linn Maren; Sørvik, Anne Grete Eide; Skaala, Øystein; Barlaup, Bjørn; Glover, Kevin (Journal article; Peer reviewed, 2014-01-27)The role of escaped farmed salmon in spreading infectious agents from aquaculture to wild salmonid populations is largely unknown. This is a case study of potential disease interaction between escaped farmed and wild fish ... -
