Distribution of Kudoa thyrsites (Cnidaria, Myxozoa) myoliquefactive stages in Northeast Atlantic mackerel (Scomber scombrus) inferred from qPCR and histology
Giulietti, Lucilla; Johansen Nedberg, Heidi; Karlsbakk, Egil Erlingsson; Marathe, Nachiket Prakash; Storesund, Julia Endresen; Mæhle, Stig; Fiksdal, Ingrid Uglenes; Ghebretnsae, Dawit Berhe; Levsen, Arne (Peer reviewed; Journal article, 2022)Kudoa thyrsites is a myxosporean parasite (Cnidaria, Myxozoa) that infects the skeletal and cardiac muscle of Northeast Atlantic (NEA) mackerel (Scomber scombrus). Heavy infections are associated with post-mortem myoliquefaction ... -
The effect of temperature on the survival of salmonid alphavirus analysed using in vitro and in vivo methods
Jarungsriapisit, Jiraporn; Nuñez-Ortiz, Noelia; Nordbø, Julie Karoline H.; Moore, Lindsey; Mæhle, Stig; Patel, Sonal (Peer reviewed; Journal article, 2020)Disease outbreaks in fish aquaculture are often of concern due to the possibility of pathogen transmission to fish in neighbouring farms and to wild fish populations. To be able to assess the risk and manage transmission ... -
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 ... -
Heterochiasmy and the establishment of gsdf as a novel sex determining gene in Atlantic halibut
Edvardsen, Rolf Brudvik; Wallerman, Ola; Furmanek, Tomasz; Kleppe, Lene; Jern, Patric; Wallberg, Andreas; Kjærner-Semb, Erik Nordtorp; Mæhle, Stig; Olausson, Sara; Sundström, Elisabeth; Harboe, Torstein; Mangor-Jensen, Ragnfrid; Drønen, Margareth Møgster; Perrichon, Prescilla; Norberg, Birgitta; Rubin, Carl-Johan (Peer reviewed; Journal article, 2022)Atlantic Halibut (Hippoglossus hippoglossus) has a X/Y genetic sex determination system, but the sex determining factor is not known. We produced a high-quality genome assembly from a male and identified parts of chromosome ... -
Long-term persistence of piscine orthoreovirus-1 (PRV-1) infection during the pre-smolt stages of Atlantic salmon in freshwater
Kannimuthu, Dhamotharan; Roh, HyeongJin; Penaranda, Ma Michelle Demogina; Wessel, Øystein; Mæhle, Stig; Ghebretnsae, Dawit Berhe; Nordbø, Joachim; Kvamme, Bjørn Olav; Morton, Hugh Craig; Grove, Søren (Peer reviewed; Journal article, 2023)Piscine orthoreovirus (PRV) causes heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon. During salmon production cycles, HSMI has predominantly been observed after seawater transfer. More recently, ... -

Repeated exposure affects susceptibility and responses of Atlantic salmon (Salmo salar) towards the ectoparasitic salmon lice (Lepeophtheirus salmonis)
Ugelvik, Mathias Stølen; Mennerat, Adele; Mæhle, Stig; Dalvin, Sussie Trine (Peer reviewed; Journal article, 2023)Atlantic salmon (Salmo salar) is repeatedly exposed to and infected with ectoparasitic salmon lice (Lepeophtheirus salmonis) both in farms and in nature. However, this is not reflected in laboratory experiments where fish ... -
Temperature affects settlement success of ectoparasitic salmon lice (Lepeophtheirus salmonis) and impacts the immune and stress response of Atlantic salmon (Salmo salar)
Ugelvik, Mathias Stølen; Mæhle, Stig; Dalvin, Sussie (Peer reviewed; Journal article, 2022)In this study, the effect of temperature on Atlantic salmon (Salmo salar) stress and immune response to the ectoparasitic salmon lice (Lepeophtheirus salmonis) was investigated. We found that infestation affected the ... -
The gill parasite Paramoeba perurans compromises aerobic scope, swimming capacity and ion balance in Atlantic salmon.
