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 ... -
Effects of alkylphenols (C4-C7) on the reproductive system of Atlantic cod (Gadus morhua)
Meier, Sonnich (Doctoral thesis, 2007-06-15)The work in this thesis is a part of a strategic work at the Institute of Marine Research, which aims to develop a variety of methods to be used in investigating potential endocrine disruption in Atlantic cod (Gadus morhua). ... -
Environmentally realistic concentrations of chlorinated, brominated, and fluorinated persistent organic pollutants induce the unfolded protein response as a shared stress pathway in the liver of Atlantic cod (Gadus morhua)
Olsvik, Pål Asgeir; Meier, Sonnich; Zhang, Xiaokang; Goksøyr, Anders; Karlsen, Odd André; Yadetie, Fekadu (Journal article; Peer reviewed, 2023)In the North Sea and North Atlantic coastal areas, fish experience relatively high background levels of persistent organic pollutants. This study aimed to compare the mode of action of environmentally relevant concentrations ... -
Expression and localization of the aryl hydrocarbon receptors and cytochrome P450 1A during early development of Atlantic cod (Gadus morhua)
Aranguren Abadía, Libe; Donald, Carey; Eilertsen, Mariann; Gharbi, Naouel; Tronci, Valentina; Sørhus, Elin; Mayer, Philipp; Nilsen, Tom Ole; Meier, Sonnich; Goksøyr, Anders; Karlsen, Odd Andre (Journal article; Peer reviewed, 2020)The aryl hydrocarbon receptor (Ahr) is a ligand-activated transcription factor that mediates the toxicity of dioxins and dioxin-like compounds (DLCs) in vertebrates. Two clades of the Ahr family exist in teleosts (Ahr1 and ... -
Parasite development affect dispersal dynamics; infectivity, activity and energetic status in cohorts of salmon louse copepodids
Skern-Mauritzen, Rasmus; Sissener, Nini; Sandvik, Anne Dagrun; Meier, Sonnich; Sævik, Pål Næverlid; Skogen, Morten D.; Vågseth, Tone; Dalvin, Sussie; Skern-Mauritzen, Mette; Bui, Samantha (Journal article; Peer reviewed, 2020)The salmon louse, Lepeophtheirus salmonis, is a parasitic copepod infecting wild and farmed salmonid fishes in the northern hemisphere. It has a direct lifecycle with a planktonic dispersal phase and an infective copepodid ... -
Photo-enhanced toxicity of crude oil on early developmental stages of Atlantic cod (Gadus morhua)
Aranguren Abadía, Libe; Yadetie, Fekadu; Donald, Carey; Sørhus, Elin; Myklatun, Lars Eirik; Zhang, Xiaokang; Lie, Kai Kristoffer; Perrichon, Prescilla; Nakken, Charlotte Langeland; Durif, Caroline; Shema, Steven; Browman, Howard; Skiftesvik, Anne Berit; Goksøyr, Anders; Meier, Sonnich; Karlsen, Odd André (Journal article; Peer reviewed, 2022)Photo-enhanced toxicity of crude oil is produced by exposure to ultraviolet (UV) radiation. Atlantic cod (Gadus morhua) embryos were exposed to crude oil with and without UV radiation (290–400 nm) from 3 days post fertilization ...
