    • Omega-3 Fatty Acids and Cardiovascular Diseases: Effects, Mechanisms and Dietary Relevance 

      Mæhre, Hanne K; Jensen, Ida-Johanne; Elvevoll, Edel Oddny; Eilertsen, Karl-Erik (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09-18)
      ω-3 fatty acids (n-3 FA) have, since the 1970s, been associated with beneficial health effects. They are, however, prone to lipid peroxidation due to their many double bonds. Lipid peroxidation is a process that may lead to increased oxidative stress, a condition associated with adverse health effects. Recently, conflicting evidence regarding the health benefits of intake of n-3 from seafood or ...
    • On the numerous concepts in invasion biology 

      Falk-Petersen, Jannike; Bøhn, Thomas; Sandlund, Odd Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2006-01-20)
      The study of biological invasions has triggered the production of a diversity of concepts. The terminology has, however, often been applied inconsistently and inaccurately. This article lists and assesses the most commonly used terms and concepts in invasion ecology. In each case the most coherent definition and use is suggested.
    • Opportunity Cost of Environmental Conservation in the Presence of Externalities: Application to the Farmed and Wild Salmon Trade-Off in Norway 

      Nikitina, Ekaterina (Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-08-17)
      Estimation of the opportunity cost is necessary for the economic assessment of environmental conservation policies. This paper considers the case where an environmental good is negatively affected in the process of the production of marketable goods. In the presence of externalities, conservation implies the undertaking of abatement measures by polluters. A relevant measure of opportunity cost in ...

    • Optimal Selection and Effort in a Fishery on a Stock with Cannibalistic Behaviour : The Case of the Northeast Arctic Cod Fisheries 

      Eide, Arne; Wikan, Arild (Journal article; Tidsskriftartikkel; Peer reviewed, 2010)
      We explore a fishery targeting the mature part of a stock, while bycatching the immature part. Both targeted catch and bycatch may have positive market values. Cost of effort is supposed to be a function of the selection properties of the fishing gears. Mature fish is assumed to cannibalise on the immature part of the stock. A bioeconomic model of the problem is set up and it is shown that the model ...
    • A parable of compliance issues and their link to EBFM outcomes. 

      Pope, John; Weber, Charlotte Teresa (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-14)
      <p>Fisheries Stakeholders are understandably most concerned with immediate problems. Often these problems are related to proposed rule changes. This short term focus is in itself a serious problem for introducing Ecosystems Based Fisheries Management (EBFM), which is typically seen as a long-term approach. However, the short-term response of fishers to rule changes may well have long-term consequences ...
    • Paralithocins, Antimicrobial Peptides with Unusual Disulfide Connectivity from the Red King Crab, Paralithodes camtschaticus 

      Moe, Morten Kaare; Haug, Tor; Sydnes, Magne Olav; Sperstad, Sigmund; Li, Chun; Vaagsfjord, Lena Christine; de la Vega, Enrique; Stensvåg, Klara (Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-01-17)
      As part of an ongoing exploration of marine invertebrates as a source of new antimicrobial peptides, hemocyte extracts from the red king crab, <i>Paralithodes camtschaticus</i>, were studied. Three cationic cysteine (Cys)-rich peptides, named paralithocins 1–3, were isolated by bioassay-guided purification, and their amino acid sequences determined by Edman degradation and expressed sequences tag ...
    • Parasitism and the Biodiversity-Functioning Relationship 

      Frainer, André; McKie, Brendan G.; Amundsen, Per-Arne; Knudsen, Rune; Lafferty, Kevin D. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-15)
      Species interactions can influence ecosystem functioning by enhancing or suppressing the activities of species that drive ecosystem processes, or by causing changes in biodiversity. However, one important class of species interactions – parasitism – has been little considered in biodiversity and ecosystem functioning (BD-EF) research. Parasites might increase or decrease ecosystem processes by ...
    • A participatory scenario method to explore the future of marine social‐ecological systems 

      Planque, Benjamin; Mullon, Christian; Arneberg, Per; Eide, Arne; Fromentin, Jean-Marc; Heymans, Johanna J; Hoel, Alf Håkon; Niiranen, Susa; Ottersen, Geir; Sandø, Anne Britt; Sommerkorn, Martin; Thébaud, Olivier; Thorvik, Thorbjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-01)
      Anticipating future changes in marine social‐ecological systems (MSES) several decades into the future is essential in the context of accelerating global change. This is challenging in situations where actors do not share common understandings, practices, or visions about the future. We introduce a dedicated scenario method for the development of MSES scenarios in a participatory context. The objective ...
    • Peptide from sea anemone metridium senile affects transient receptor potential ankyrin-repeat 1 (TRPA1) function and produces analgesic effect 

      Logashina, Yulia A.; Mosharova, Irina V.; Korolkova, Yulia V.; Shelukhina, Irina V; Dyachenko, Igor A.; Palikov, Victor A.; Palikova, Yulia A.; Murashev, Arkadii N.; Kozlov, Sergey A.; Stensvåg, Klara; Andreev, Yaroslav A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01-11)
      The Transient Receptor Potential Ankyrin-repeat 1 (TRPA1) is an important player in pain and inflammatory pathways. It is a promising target for novel drugs development for treatment of a number of pathological states. A novel peptide producing significant potentiating effect (up to ~90%) on AITC- and diclofenac-induced currents of TRPA1 was isolated from the venom of sea anemone <i>Metridium ...
    • Peracetic acid as a potential treatment for amoebic gill disease (AGD) in Atlantic salmon - Stage 1 

      Lazado, Carlo C.; Timmerhaus, Gerrit; Pedersen, Lars-Flemming; Pittman, Karin; Soleng, Malene; Haddeland, Sindre; Johansen, Lill-Heidi; Breiland, Mette Serine Wesmajervi; Rørmark, Lisbeth; Mohammad, Saima; Hytterød, Sigurd (Research report; Forskningsrapport, 2019-06)
      PERAGILL is an initiative that ultimately aims to develop an alternative treatment for the currently available therapies for amoebic gill disease (AGD) that have several practical and environmental issues. Peracetic acid (PAA) is a potent oxidant with a broad spectrum of antimicrobial activity and decays into relatively safe residuals, thus, has been widely recognised as a sustainable disinfectant ...
    • Performance of the Nordmøre grid in shrimp trawling and potential effects of guiding funnel length and light stimulation 

      Larsen, Roger B.; Herrmann, Bent; Sistiaga, Manu Berrondo; Brinkhof, Jesse; Tatone, Ivan; Langård, Lise (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-31)
      The introduction of the Nordmøre grid to shrimp trawls has reduced the issue of bycatch to that of small-sized species and juveniles that are able to pass through the grid and enter the small-meshed cod end together with the targeted shrimp. This study estimated the size- and species-selective performance of the Nordmøre grid in the configuration most often applied by fishermen and made a preliminary ...

    • Persistence of environmental DNA in marine systems 

      Collins, Rupert A.; Wangensteen Fuentes, Owen Simon; O'Gorman, Eoin J.; Mariani, Stefano; Sims, David W.; Genner, Martin J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-05)
      As environmental DNA (eDNA) becomes an increasingly valuable resource for marine ecosystem monitoring, understanding variation in its persistence across contrasting environments is critical. Here, we quantify the breakdown of macrobial eDNA over a spatio-temporal axis of locally extreme conditions, varying from ocean-influenced offshore to urban-inshore, and between winter and summer. We report that ...
    • Perturbation of seafloor bacterial community structure by drilling waste discharge 

      Nguyen, Tan Thi; Cochrane, Sabine K.J.; Landfald, Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-31)
      Offshore drilling operations result in the generation of drill cuttings and localized smothering of the benthic habitats. This study explores bacterial community changes in the in the upper layers of the seafloor resulting from an exploratory drilling operation at 1400 m water depth on the Barents Sea continental slope. Significant restructurings of the sediment microbiota were restricted to the ...

    • Physical and Quality Attributes of Salted cod (Gadus morhua L.) as Affected by the State of Rigor and Freezing Prior to Salting 

      Lauritzsen, Kristin; Olsen, Ragnar L.; Akse, Leif; Johansen, Arvid; Joensen, Sjurður; Sørensen, Nils Kristian (Journal article; Tidsskriftartikkel; Peer reviewed, 2004-03-04)
      The effects of the rigor state and freezing of cod prior to salting on the mass transfer during production and the quality of heavily cured cod have been investigated. Pre-rigor salting lead to a larger reduction in weight, a higher water loss and a lower uptake of NaCl than in fish salted post-rigor and in fish salted after frozen storage. The cause of this is believed to be the simultaneous influx ...
