    • Complex and divergent histories gave rise to genome-wide divergence patterns amongst European whitefish (Coregonus lavaretus) 

      Crotti, Marco; Bean, Colin W.; Gowans, Andy R. D.; Winfield, Ian J.; Butowska, Magdalena; Wanzenböck, Josef; Bondarencko, Galina; Præbel, Kim; Adams, Colin E.; Elmer, Kathryn R. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-15)
      Pleistocene glaciations dramatically affected species distribution in regions that were impacted by ice cover and subsequent postglacial range expansion impacted contemporary biodiversity in complex ways. The European whitefish, Coregonus lavaretus, is a widely distributed salmonid fish species on mainland Europe, but in Britain it has only seven native populations, all of which are found on the ...
    • The components of a food traceability system 

      Olsen, Petter; Borit, Melania (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-03)
      <p><i>Background</i>: Traceability of food products has become the focus of regional and national legislation, of many research and technical development initiatives and projects, and of many scientific articles. However, most of the scientific publications do not differentiate between the components of a traceability system, and those who do to some degree use inconsistent terminology and definitions. ...
    • Composition of exosomes derived from Atlantic salmon (Salmo salar) head kidney leukocytes 

      Strandskog, Guro; Sobhkhez, Mehrdad; Jørgensen, Jorunn B; Iliev, Dimitar Borisov (Conference object; Konferansebidrag, 2015-06-28)
      Exosomes are secreted nanosize vesicles (30−100 nm) derived from multivesicular endosomes. Exosomes are released by different immune cell types, including T- and B-lymphocytes, mast cells and antigen-presenting cells (APCs). The composition of exosomes - including protein and RNA content reflects their endosomal origin and the type of cells that produce them. Mammalian APCs produce large amounts ...

    • Conflicts and trade-offs in implementing the Common Fisheries Policy (CFP) discard policy 

      Borges, Lisa; Nielsen, Kåre Nolde; Frangoudes, Katia; Armstrong, Claire W.; Borit, Melania (Research report; Forskningsrapport, 2018-05-01)
      The introduction of the Landing Obligation (LO) is one of the most significant reform elements in the 2013 Common Fisheries Policy (CFP). In order to assess how the LO performs as a policy instrument, it is essential to understand the background, objectives and motivation that led to the policy being adopted. With these objectives in mind, a desk-study was first carried out to review relevant policy ...
    • Conservation of Genomic Information in Multiple Displacement Amplified Low-Quantity Metagenomic Material from Marine Invertebrates 

      Elvheim, Andrea Iselin; Li, Chun; Landfald, Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-02)
      Marine invertebrate microbiomes have been a rich source of bioactive compounds and interesting genomic features. In cases where the achievable amounts of metagenomic DNA are too low for direct sequencing, multiple displacement amplification (MDA) can be used for whole genome amplification. However, MDA has known limitations which can affect the quality of the resulting genomes and metagenomes. ...
    • Consumer preference for eco-labelled aquaculture products in Vietnam 

      Bui, Bich Xuân (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-01)
      Product labelling with eco-certifications is market-based incentive tool for sustainable aquaculture, thus mitigating negative environmental impacts. The aims of this study are to investigate: i) whether consumers prefer eco-labelled (eco-certified) shrimps over conventional (non-certified) shrimp; and ii) whether consumers prefer specific eco-label (eco-certification logo) over others. The study ...
    • Coproducing Sea Ice Predictions with Stakeholders Using Simulation 

      Blair, Berill; Müller, Malte; Palerme, Cyril; Blair, Rayne; Crookall, David; Knol-Kauffman, Maaike; Lamers, Machiel (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-15)
      Forecasts of sea ice evolution in the Arctic region for several months ahead can be of considerable socioeconomic value for a diverse range of marine sectors and for local community supply logistics. However, subseasonal-to-seasonal (S2S) forecasts represent a significant technical challenge, and translating user needs into scientifically manageable procedures and robust user confidence requires ...
    • Cost-benefit analysis of aquaculture expansion in Arctic Norway 

      Aanesen, Margrethe; Mikkelsen, Eirik Inge (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-22)
      According to governmental plans, Norway faces huge expansions in the production of farmed Atlantic salmon. However, it is municipalities that designate coastal areas to aquaculture activities and their motivation depends on net benefits at municipal level from such use. Yet, there is little empirical evidence on costs and benefits of using coastal areas to aquaculture activities. We set up a ...
    • Could green artificial light reduce bycatch during Barents Sea Deep-water shrimp trawling? 

      Larsen, Roger B.; Herrmann, Bent; Sistiaga, Manu Berrondo; Brčić, Jure; Brinkhof, Jesse; Tatone, Ivan (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-31)
      The Nordmøre grid is widely used in shrimp trawls to reduce the bycatch of fish species. However, small-sized fish species and juveniles still pass through the grid and enter the codend, along with the targeted shrimp. This bycatch of small fish has a negative impact on the ecosystem due to increased fish mortality, and leads to additional sorting work onboard. Some small-sized fish that enter the ...
    • CpG oligonucleotides bind TLR9 and RRM-Containing proteins in Atlantic Salmon (Salmo salar) 

      Iliev, Dimitar Borisov; SkjÆveland, ingrid; Jørgensen, Jorunn B (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Background: Bacterial DNA is well-known for its potent immunostimulatory properties which have been attributed to the abundance of CpG dinucleotides within the genomes of prokaryotes. Research has found that mammalian TLR9 is a receptor which mediates the immune response to CpG DNA; however, its functional properties in non-mammalian vertebrates are still poorly characterized. Leukocytes isolated ...
    • CpG- and LPS-activated MAPK signaling in in vitro cultured salmon (Salmo salar) mononuclear phagocytes 

      Iliev, Dimitri Borisov; Hansen, Tom Egil; Jørgensen, Sven Martin; Krasnov, Aleksei; Jørgensen, Jorunn B (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      The Mitogen-activated protein kinases (MAPK) are involved in transmitting intracellular signals downstream of diverse cell surface receptors and mediate the response to ligands such as growth factors, hormones and cytokines. In addition, MAPK are critically involved in the innate immune response to pathogen-derived substances, commonly referred to as pathogen-associated molecular patterns (PAMPs), ...
    • CpGs Induce Differentiation of Atlantic Salmon Mononuclear Phagocytes Into Cells With Dendritic Morphology and a Proinflammatory Transcriptional Profile but an Exhausted Allostimulatory Activity 

      Iliev, Dimitar Borisov; Lagos, Leidy; Thim, Hanna Leena; Jørgensen, Sven Martin; Krasnov, Aleksei; Jørgensen, Jorunn B (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-13)
      Due to their ability to present foreign antigens and prime naïve T cells, macrophages, and dendritic cells (DCs) are referred to as professional antigen-presenting cells (APCs). Although activated macrophages may function as APCs, these cells are particularly effective at directly engaging pathogens through phagocytosis, and production of antimicrobial compounds. On the other hand, DCs possess superb ...
    • Creating political spaces at sea - governmentalisation and governability in Norwegian fisheries 

      Johnsen, Jahn Petter (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-30)
      How do technologies of power make the world governable? The understanding of how management techniques create governability remains rather poor. In this article, I analyse how spatial regulation in Norwegian fisheries direct human behaviour towards scientific, political, and administrative objectives. Like other fisheries’ regulations, they contribute to governmentalisation and governability, and ...
    • The creation of coastal space – how local ecological knowledge becomes relevant 

      Johnsen, Jahn Petter; Hersoug, Bjørn; Solås, Ann-Magnhild (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
      Since the 1990s, substantial efforts have been invested in Local Ecological Knowledge (LEK) research, but LEK has only been applied in western fisheries and resource management to a limited extent. The attempts to link LEK to model-based fish stock assessment seem to have failed largely because the format of LEK does not fit into the models currently in use. However, LEK is still relevant for ...
    • CREELSELECT—A method for determining the optimal creel mesh: Case study on Norway lobster (Nephrops norvegicus) fishery in the Mediterranean Sea 

      Brčić, Jure; Herrmann, Bent; Mašanović, Marina; Šifner, Svjetlana Krstulović; Škeljo, Frane (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-31)
      In the laboratory, we investigated which sizes of <i>Nephrops</i> (<i>Nephrops norvegicus</i>) could pass through the meshes of different size and shape to establish a predictive model for the creels size selectivity. Predictions agreed well with the results from experimental fishing, demonstrating the reliability of this simple method. <i>Nephrops</i> minimum target size is 20 mm carapace length ...

      Olsen, Stein Harris; Nilsen, Heidi; Larssen, Kjell; Svalheim, Ragnhild Aven; Midling, Kjell Øyvind (Conference object; Konferansebidrag, 2016-08-16)
      The overall goal for CRISP (WP 5) is to contribute to, and develop, the competitive power of the trawling fleet by implement new technology and knowledge. The focus is on the processing, from when the fish is in the trawl at the seabed until the processed and finished raw material is packed and in storage.
    • CRISPR/Cas9-Mediated Gene Editing in Salmonids Cells and Efficient Establishment of Edited Clonal Cell Lines 

      Strømsnes, Trygve; Schmidke, Sebastian; Azad, Mitra; Singstad, Øyvind; Grønsberg / Mikkelsen, Idun Merete; Dalmo, Roy Ambli; Okoli, Arinze Stanley (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-19)
      Finfish production has seen over three-fold increase in the past 30 years (1990–2020), and Atlantic salmon (A. salmon; salmo salar) accounted for approximately 32.6% of the total marine and coastal aquaculture of all finfish species in the year 2020, making it one of the most profitable farmed fish species globally. This growth in production is, however, threatened by a number of problems which can ...
