Alkyl-phenanthrenes in early life stage fish: differential toxicity in Atlantic haddock (Melanogrammus aeglefinus) embryos
Donald, Carey; Nakken, Charlotte L.; Sørhus, Elin; Perrichon, Prescilla; Jørgensen, Kåre Bredeli; Bjelland, Hege K.; Stølen, Christine; Kancherla, Sindhu; Mayer, Philipp; Meier, Sonnich (Journal article; Peer reviewed, 2023)Tricyclic polycyclic aromatic hydrocarbons (PAHs) are believed to be the primary toxic components of crude oil. Such compounds including phenanthrene are known to have direct effects on cardiac tissue, which lead to ... -
Co-Exposure of Phenanthrene and the cyp-Inducer 3-Methylchrysene Leads to Altered Biotransformation and Increased Toxicity in Fish Egg and Larvae
Donald, Carey; Sørhus, Elin; Perrichon, Prescilla; Nakken, Charlotte L.; Goksøyr, Anders; Jørgensen, Kåre Bredeli; Mayer, Philipp; da Silva, Denis A.M.; Meier, Sonnich (Journal article; Peer reviewed, 2023)Polycyclic aromatic hydrocarbons (PAHs) have frequently been suspected of governing crude oil toxicity because of similar morphological defects in fish. However, PAH concentrations are often not high enough to explain the ... -
Co-exposure to UV radiation and crude oil increases acute embryotoxicity and sublethal malformations in the early life stages of Atlantic haddock (Melanogrammus aeglefinus)
Sørhus, Elin; Donald, Carey; Nakken, Charlotte L.; Perrichon, Prescilla; Durif, Caroline; Shema, Steven; Browman, Howard; Skiftesvik, Anne Berit; Lie, Kai Kristoffer; Rasinger, Josef; Müller, Mette Helen Bjørge; Meier, Sonnich (Journal article; Peer reviewed, 2023)Crude oil causes severe abnormalities in developing fish. Photomodification of constituents in crude oil increases its toxicity several fold. We report on the effect of crude oil, in combination with ultraviolet (UV) ... -
Crude oil exposures reveal roles for intracellular calcium cycling in haddock craniofacial and cardiac development
Sørhus, Elin; Incardona, John P.; Karlsen, Ørjan; Linbo, Tiffany; Sørensen, Lisbet; Nordtug, Trond; van der Meeren, Terje; Thorsen, Anders; Thorbjørnsen, Maja; Jentoft, Sissel; Edvardsen, Rolf; Meier, Sonnich (Peer reviewed; Journal article, 2016-08-10)Recent studies have shown that crude oil exposure affects cardiac development in fish by disrupting excitation-contraction (EC) coupling. We previously found that eggs of Atlantic haddock (Melanogrammus aeglefinus) bind ... -
Discovery of polycyclic aromatic acid metabolites in fish exposed to the petroleum compounds 1-methylphenanthrene and 1,4-dimethylphenanthrene
Nakken, Charlotte Langeland; Meier, Sonnich; Mjøs, Svein Are; Bijlsma, Lubertus; Rowland, Steven J; Donald, Carey (Journal article; Peer reviewed, 2024)Most of the polycyclic aromatic hydrocarbons (PAHs) in petroleum are alkylated (alkyl PAHs), still the metabolism of these alkyl PAHs to the expected acid products (polycyclic aromatic acids; PAAs) has yet to be demonstrated ... -
Effects of fish farm activities on the sponge Weberella bursa, and its associated microbiota
Laroche, Olivier; Meier, Sonnich; Mjøs, Svein A.; Keeley, Nigel B. (Journal article; Peer reviewed, 2021)Sustained growth of world-wide sea farming and the search of optimal growing conditions have driven several countries, including Norway, to establish new finfish sites in more exposed, high current locations. Characterized ... -
Exposure of Polycyclic Aromatic Hydrocarbons (PAHs) and Crude Oil to Atlantic Haddock (Melanogrammus aeglefinus): A Unique Snapshot of the Mercapturic Acid Pathway
Nakken, Charlotte Langeland; Berntssen, Marc HG; Meier, Sonnich; Bijlsma, Lubertus; Mjøs, Svein Are; Sørhus, Elin; Donald, Carey (Journal article; Peer reviewed, 2024)Fish exposed to xenobiotics like petroleum-derived polycyclic aromatic hydrocarbons (PAHs) will immediately initiate detoxification systems through effective biotransformation reactions. Yet, there is a discrepancy between ... -
Oil droplet fouling and differential toxicokinetics of polycyclic aromatic hydrocarbons in embryos of Atlantic haddock and cod
Sørensen, Lisbet; Sørhus, Elin; Nordtug, Trond; Incardona, John P.; Linbo, Tiffany; Giovanetti, Laura; Karlsen, Ørjan; Meier, Sonnich (Peer reviewed; Journal article, 2017-07-05)The impact of crude oil pollution on early life stages (ELS) of fish, including larvae and embryos, has received considerable attention in recent years. Of the organic components present in crude oil, polycyclic aromatic ... -
SuspensionFeeding Benthic Species’ Physiological and Microbiome Response to Salmon Farming and Associated Environmental Changes
Laroche, Olivier; Meier, Sonnich; Mjøs, Svein Are; Keeley, Nigel B. (Journal article; Peer reviewed, 2022)Caged salmon farming is increasingly undertaken in water bodies with strong hydrodynamics where hard and mixed substrate habitats are more prevalent. Yet, these structurally complex and heterogeneous habitats support diverse ...
