    • Transcriptome analysis of plasmid-induced genes sheds light on the role of type I IFN as adjuvant in DNA vaccine against infectious salmon anemia virus 

      Sobhkhez, Mehrdad; Krasnov, Aleksei; Chang, Chia Jung; Robertsen, Børre (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-21)
      A previous study showed that a plasmid expressing IFNa (pIFNa) strongly enhanced protection and antibody production of a DNA vaccine against infectious salmon anemia virus (ISAV) in Atlantic salmon. The vaccine consisted of a plasmid (pHE) expressing the virus hemagglutinin-esterase as an antigen. To increase the understanding of the adjuvant effect of pIFNa, we here compared transcriptome responses ...
    • The Transformation of Extralegal Principles into Legal Principles by the International Court of Justice in The Hague: Illustrated by a Peaceful Delimitation of «the Promised Land» 

      Ørebech, Peter Th (Journal article; Tidsskriftartikkel; Peer reviewed, 2020)
      Social norms are mixtures of extralegal and legal principles. The International Court of Justice‟ in The Hague‟s (ICJ) adjudication subtracts normative structures from different sources, moral, ethical, religious etc. dogmas amplifying its case law. The failing Israel-Palestine reconciliation that results from “power asymmetries” and “supreme emergency exception”, illustrates how absence of concomitant ...

      The oceans have become a juncture of great visions of blue growth as well as strong environmental concern. This paper discusses the essential role of the social sciences as the oceans increasingly emerge as a contested social arena. The marine social sciences have generated a vast knowledge about the development of fisheries and the implications of fisheries policies on coastal communities. We review ...
    • Transforming conflicts from the bottom-up? Reflections on civil society efforts to empower marginalized fishers in postwar Sri Lanka 

      Scholtens, Joeri; Bavinck, Jan Maarten (Journal article; Tidsskriftartikkel; Peer reviewed, 2018)
      We analyze the efforts of an international consortium of academics and activists to understand and address a transnational fisheries conflict in South Asia. The so-called REINCORPFISH project (2010–2016) focused on an asymmetrical conflict between trawler fishers from the Indian state of Tamil Nadu who frequently transgress into Sri Lankan waters and northern Sri Lankan fishers, whose livelihoods ...
    • Transforming the governance of small-scale fisheries 

      Chuenpagdee, Ratana; Jentoft, Svein (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-16)
      Despite their contribution to employment, food security, poverty eradication, and community well-being, small-scale fisheries often find themselves in a disadvantageous position globally relative to large-scale fisheries and other industries competing for marine space, resources, and government attention. By and large, small-scale fisheries are marginalized in every sense of the word: culturally, ...
    • Transgene and immune gene expression following intramuscular injection of Atlantic salmon (Salmo salar L.) with DNA-releasing PLGA nano- and microparticles 

      Hølvold, Linn Benjaminsen; Fredriksen, Børge Nilsen; Bøgwald, Jarl; Dalmo, Roy Ambli (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      The use of poly-(D,L-lactic-co-glycolic) acid (PLGA) particles as carriers for DNA delivery has received considerable attention in mammalian studies. DNA vaccination of fish has been shown to elicit durable transgene expression, but no reports exist on intramuscular administration of PLGA-encapsulated plasmid DNA (pDNA). We injected Atlantic salmon (Salmo salar L.) intramuscularly with a plasmid ...
    • Trapped in the TAC Machine: Making a Fisheries-Based Indicator System for Coastal Cod in Steigen, Norway 

      Holm, Petter; Aglen, Asgeir; Bjørkan, Maiken; Andersen, Jan (Chapter; Bokkapittel, 2020)
      The GAP project is concerned with the lack of stakeholder participation in providing knowledge for management. This creates a legitimacy problem as the fishermen do not get to share the knowledge basis for and justification of management decisions. In addition, fishermen’s experience-based knowledge remains unused. GAP intends to bridge the legitimacy and knowledge gaps, finding practical ways for ...

    • Trends in mussel cover, density and size at exploited and unexploited intertidal reefs in eastern South Africa 

      Steyn, E.; Groeneveld, J.C.; Santos, Jorge; Mselegu, X.I. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-20)
      The brown mussel Perna perna is the dominant indigenous mussel along the east coast of South Africa, where it is harvested by recreational and subsistence fishers. High fishing pressure near urban areas led to declining abundance and consequently to the closure of some reefs to fishing in 1998. We estimated trends in mussel population dynamics at exploited and unexploited sites, along fixed transects, ...

      Global environmental changes may have a profound impact on ecosystems. In this context, it is crucial to gather biological and ecological information of the main species in marine communities to predict and mitigate potential effects of shifts in their distribution, abundance, and interactions. Using genotyping by sequencing (GBS), we assessed the genetic structure of a keystone species in the ...
    • Ultrafiltration of Saithe (Pollachius virens) Protein Hydrolysates and Its Effect on Antioxidative Activity 

      Hjellnes, Veronica Hammer; Rustad, Turid; Jensen, Ida-Johanne; Eiken, Elin; Pettersen, Stine Marie; Falch, Eva (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-30)
      The whitefish industry generates a huge amount of rest raw material, which is currently wasted or underutilized in the production of low-value products such as animal feed. While fish muscle is the primary product of use for human consumption, rest raw material has great potential as a source of protein and bioactive peptides for the production of food ingredients and nutraceuticals. Enzymatic ...
    • Ultrasonic imaging as a means of monitoring gonadal development in lumpfish (Cyclopterus lumpus) 

      Mlingi, Frank Thomas; Puvanendran, Velmurugu; Burgerhout, Erik; Tveiten, Helge; Tomkiewicz, Jonna; Kjørsvik, Elin; Mommens, Maren (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-21)
      The commercial farming of juvenile lumpfish requires monitoring of gonadal development to achieve synchronized production. Conventional methods such as gonadosomatic index (GSI), sex hormone analyses, gonadal histology, endoscopy, and gene expression analyses are costly, invasive, and often involve sacrificing the fish. We assessed the efficiency of ultrasound as a non-invasive method for monitoring ...
    • Uncovering neutral and adaptive genomic differentiation among European perch with brackish water and freshwater origin in the western Baltic Sea region 

      Skovrind, Mikkel; Pacheco, George; Christensen, Emil Aputsiaq Flindt; Gopalakrishnan, Shyam; Fietz, Katharina; Holm-Hansen, Tore Hejl; Vieira, Filipe Garrett; Krag, Marcus Anders; Carl, Henrik; Gilbert, Marcus Thomas Pius; Olsen, Morten Tange; Møller, Peter Daniel Rask (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-13)
      Environmental variation across the range of wild species can lead to local adaptations. The Baltic Sea was formed when the Fenno-Scandian ice sheet retreated around 12 thousand years ago, creating a new brackish water habitat colonised by both marine and freshwater fish species. The European perch (Perca fluviatilis) is a predatory freshwater fish with a large geographical distribution across ...
    • Under the canopy: Community-wide effects of invasive algae in Marine Protected Areas revealed by metabarcoding

      We analysed with multigene (18S and COI) metabarcoding the effects of the proliferation of invasive seaweeds on rocky littoral communities in two Spanish Marine Protected Areas. The invasive algae studied were <i>Caulerpa cylindracea</i>, <i>Lophocladia lallemandii</i> and <i>Asparagopsis armata</i>. They are canopy-forming, landscape-dominant seaweeds, and we were interested in their effects on the ...
    • Understanding and predicting size selection in diamond-mesh cod ends for Danish seining: a study based on sea trials and computer simulations 

      Herrmann, Bent; Krag, Ludvig Ahm; Feekings, Jordan; Noack, Thomas (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-06-28)
      Danish seining is an important fishing method used to harvest demersal species. Knowledge about the size selectivity of different demersal species with this type of fishing gear is therefore of importance for managing the exploitation of marine resources. However, there are only limited data on size selection in cod ends in this fishery. Sea trials were therefore carried out to collect size selectivity ...
