An annual profile of the impacts of simulated oil spills on the Northeast Arctic cod and haddock fisherie
Carroll, JoLynn; Frøysa, Håvard Guldbrandsen; Vikebø, Frode Bendiksen; Broch, Ole Jacob; Nepstad, Raymond; Augustine, Starrlight; Skeie, Geir Morten; Bockwoldt, Mathias (Peer reviewed; Journal article, 2022)We simulate the combined natural and pollutant-induced survival of early life stages of NEA cod and haddock, and the impact on the adult populations in response to the time of a major oil spill in a single year. Our ... -

Fysisk oseanografiske forhold i produksjonsområdene for akvakultur - Oppdatering september 2023
Albretsen, Jon; Asplin, Lars; Frøysa, Håvard Guldbrandsen; Sandvik, Anne Dagrun (Rapport fra havforskningen;2023 - 42, Research report, 2023)Vintermånedene januar og februar 2023 har vært noe varmere enn normalt i så å si hele landet. De påfølgende vårmånedene har hatt nær normale temperaturer. En kraftig oppvarming av overflatevannet i juni førte til at områdene ... -
Integrative omics-analysis of lipid metabolism regulation by peroxisome proliferator-activated receptor a and b agonists in male Atlantic cod
Eide, Marta; Goksøyr, Anders; Yadetie, Fekadu; Gilabert, Alejandra; Bartosova, Zdenka; Frøysa, Håvard Guldbrandsen; Fallahi, Shirin; Zhang, Xiaokang; Blaser, Nello; Jonassen, Inge; Bruheim, Per; Alendal, Guttorm; Brun, Morten; Porte, Cinta; Karlsen, Odd André (Peer reviewed; Journal article, 2023)Lipid metabolism is essential in maintaining energy homeostasis in multicellular organisms. In vertebrates, the peroxisome proliferator-activated receptors (PPARs, NR1C) regulate the expression of many genes involved in ... -
Mind the gap – Relevant design for laboratory oil exposure of fish as informed by a numerical impact assessment model
Frøysa, Håvard Guldbrandsen; Nepstad, Raymond; Meier, Sonnich; Donald, Carey; Sørhus, Elin; Bockwoldt, Mathias; Carroll, JoLynn; Vikebø, Frode Bendiksen (Peer reviewed; Journal article, 2023)Laboratory experiments provide knowledge of species-specific effects thresholds that are used to parameterize impact assessment models of oil contamination on marine ecosystems. Such experiments typically place individuals ...
