    • Marine spatial planning: risk or opportunity for fisheries in the North Sea? 

      Jentoft, Svein; Knol, Maaike (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
      The North Sea is one of the busiest marine areas in the world. It is also a major fisheries ground. Bordered by seven countries with their own spatial uses and claims, the stage is set for complex and demanding governance challenges. Recent decades have also seen user groups multiply, competition for space and resources increase, and the pressure on the marine environment and its living natural ...

    • Sequence Analysis of the Genome of Piscine Orthoreovirus (PRV) Associated with Heart and Skeletal Muscle Inflammation (HSMI) in Atlantic Salmon (Salmo salar) 

      Markussen, Turhan; Dahle, Maria Krudtaa; Tengs, Torstein; Løvoll, Marie Therese; Finstad, Øystein Wessel; Wiik-Nielsen, Christer R.; Grove, Søren; Lauksund, Reidunn Silje; Robertsen, Børre; Rimstad, Espen (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Piscine orthoreovirus (PRV) is associated with heart- and skeletal muscle inflammation (HSMI) of farmed Atlantic salmon (Salmo salar). We have performed detailed sequence analysis of the PRV genome with focus on putative encoded proteins, compared with prototype strains from mammalian (MRV T3D)- and avian orthoreoviruses (ARV-138), and aquareovirus (GCRV-873). Amino acid identities were low for ...

    • Eomesodermin of Atlantic Salmon: An Important Regulator of Cytolytic Gene and Interferon Gamma Expression in Spleen Lymphocytes 

      Kumari, Jaya; Bøgwald, Jarl; Dalmo, Roy Ambli (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Eomesodermin (Eomes), a T-bet homologue expressed in activated CD8+T cells was recently proposed to act as a master regulator of cytotoxic CD8+ T cell effector function and offers an exciting avenue for future exploration. Here, we have identified and characterized the full-length Atlantic salmon Eomes cDNA (2477 bp). Promoter analysis of the salmon Eomes showed the presence of important putative ...

    • Making ecosystem-based management operational: Integrated monitoring in Norway 

      Knol, Maaike (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Ecosystem-based management presupposes that the state and development trends of an ecosystem - or of ecological quality - can be measured and followed. Currently, in many coastal countries there exists a variety of monitoring practices that are concerned with single issues only, and are not an integrated part of a larger framework. With the trend towards more comprehensive forms of ecosystem-based ...

    • Fra nasking til næring - samarbeid om lokal utvikling 

      Johnsen, Jahn Petter (Journal article; Tidsskriftartikkel, 2012)
      Naturreservatet i St. Abbs og Eyemouth er en ressurs for lokal næringsutvikling i Skottland. Grunnlaget er et lokalt samarbeid mellom fiskere, dykkere, verneinteresser og myndigheter. Kan vi i Nord-Norge lære noe av disse erfaringene?

    • Understanding the Size Selectivity of Redfish (Sebastes spp.) in North Atlantic Trawl Codends 

      Herrmann, Bent; Sistiaga, Manu Berrondo; Nielsen, Kåre Nolde; Larsen, Roger B. (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      The majority of trawl selectivity studies for the three redfish species of particular commercial importance in North Atlantic fisheries: Sebastes marinus, Sebastes mentella and Sebastes fasciatus, are based on data collected from diamond mesh codends with mesh sizes ranging from 88 mm to 147 mm. We demonstrate how results from these studies can be understood by morphological characteristics of ...

    • Total Catch of a Red-Listed Marine Species Is an Order of Magnitude Higher than Official Data 

      Kleiven, Alf Ring; Olsen, Esben Moland; Vølstad, Jon Helge (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Accurate information on total catch and effort is essential for successful fisheries management. Officially reported landings, however, may be underestimates of total catch in many fisheries. We investigated the fishery for the nationally red-listed European lobster (Homarus gammarus) in south-eastern Norway. Probability-based strip transect surveys were used to count buoys in the study area in ...

    • Anti-infectious and anti-inflammatory effects of peptide fragments sequentially derived from the antimicrobial peptide centrocin 1 isolated from the green sea urchin, Strongylocentrotus droebachiensis 

      Bjørn, Camilla; Håkansson, Joakim; Myhrman, Emma; Sjøstrand, Veronika; Haug, Tor; Lindgren, Kerstin; Blencke, Hans-Matti; Stensvåg, Klara; Mahlapuu, Margit (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Bacterial resistance against antibiotic treatment has become a major threat to public health. Antimicrobial peptides (AMPs) have emerged as promising alternative agents for treatment of infectious diseases. This study characterizes novel synthetic peptides sequentially derived from the AMP centrocin 1, isolated from the green sea urchin, for their applicability as anti-infective agents.The microbicidal ...

    • Structure-activity relationships of the antimicrobial peptide arasin 1 - and mode of action studies of the N terminal, proline-rich region 

      Paulsen, Victoria; Blencke, Hans-Matti; Benincasa, Monica; Haug, Tor; Eksteen, Jacobus Johannes; Styrvold, Olaf B.; Scocchi, Marco; Stensvåg, Klara (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Arasin 1 is a 37 amino acid long proline-rich antimicrobial peptide isolated from the spider crab, Hyas araneus. In this work the active region of arasin 1 was identified through structure-activity studies using different peptide fragments derived from the arasin 1 sequence. The pharmacophore was found to be located in the proline/arginine-rich NH2 terminus of the peptide and the fragment arasin ...

    • Effects of similar intakes of marine n-3 fatty acids from enriched food products and fish oil on cardiovascular risk markers in healthy human subjects 

      Kirkhus, Bente; Lamglait, Amandine; Eilertsen, Karl-Erik; Falch, Eva; Haider, Trond; Vik, Hogne; Hoem, Nils; Hagve, Tor-Arne; Basu, Samar; Olsen, Elisabeth; Seljeflot, Ingebjørg; Nyberg, Lena; Elind, Elisabeth; Ulven, Stine Marie (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      There is convincing evidence that consumption of fish and fish oil rich in long-chain (LC) n-3 PUFA (n-3 LCPUFA), EPA (20 : 5n-3) and DHA (22 : 6n-3) reduce the risk of CHD. The aim of the present study was to investigate whether n-3 LCPUFA-enriched food products provide similar beneficial effects as fish oil with regard to incorporation into plasma lipids and effects on cardiovascular risk markers. ...

    • Kysten i endring: Om fiskeripolitikken som distrikts- og lokalsamfunnspolitikk 

      Vik, Jostein; Johnsen, Jahn Petter; Sønvisen, Signe Annie (Chapter; Bokkapittel, 2011)
      Norsk fiskeripolitikk har siden 1930-årene hatt et innslag av distriktspolitikk. Det har fra starten av vært et mål i fiskeripolitikken å skulle bidra til bosetting og sysselsetting i Kyst-Norge. Fra 1945 og fram til omkring 1990 var bosettings- og sysselsettingsmålet likestilt med andre mål i fiskeripolitikken. Etter ressursforvaltningens gjennombrudd i 1990 ble bærekraftig ressursutnyttelse ...

    • Institutional quality and catch performance of fishing nations 

      Flaaten, Ola (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      The relationship between annual growth in the catches of fishing nations and the quality of the institutions of those nations is analyzed. Catch volumes are used as a proxy for development, since economic performance indicators based on a common set of definitions do not exist. 49 major fishing nations were selected for this study, including 22 OECD countries and several developing countries. Three ...

    • A review of bioeconomic modelling of habitat-fisheries interactions. 

      Foley, Naomi; Armstrong, Claire W.; Kahui, Viktoria; Mikkelsen, Eirik Inge; Reithe, Siv (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      This paper reviews the bioeconomic literature on habitat-fisheries connections. Many such connections have been explored in the bioeconomic literature; however, missing from the literature is an analysis merging the potential influences of habitat on both fish stocks and fisheries into one general, overarching theoretical model. We attempt to clarify the nature of linkages between the function of ...

    • Sequential bargaining, external effects of agreement, and public intervention 

      Aanesen, Margrethe (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      In some bargaining situations, agreement has implications for agents beyond the parties involved, and if so, delays in reaching an agreement or failing to reach an agreement, when this would be profitable, may imply significant welfare losses. The question raised in this paper is whether the intervention of a government, who has a positive valuation of agreement and therefore offers a subsidy, will ...

    • Histological and bacteriological changes in intestine of beluga (Huso huso) following ex vivo exposure to bacterial strains 

      Salma, Wahida; Zhou, Zhigang; Wang, Wenwan; Askarian, Fatemeh; Kousha, Armin; Ebrahimi, Maryam Tajabadi; Myklebust, Reidar; Ringø, Einar (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      In the present study the intestinal sac method (ex vivo) was used to evaluate the interactions between lactic acid bacteria and staphylococci in the gastrointestinal (GI) tract of beluga (Huso huso). The distal intestine (DI) of beluga was exposed ex vivo to Staphylococcus aureus, Leuconostoc mesenteroides and Lactobacillus plantarum. Histological changes following bacterial exposure were assessed ...

      Knol, Maaike (Lecture; Forelesning; Peer reviewed, 2011-03-25)

    • MPA in Labor: Securing the Pearl Cays of Nicaragua 

      Gonzalez, Clarence; Jentoft, Svein (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Implementation of Marine Protected Areas (MPAs) has always a step-zero, i.e., an initial phase when the idea is incepted, communicated and negotiated among stakeholders. What happens during this phase is likely to have an impact later on. If not done right, the management of the MPA may encounter problems at later stage that will be difficult to correct. Inspired by this working theory, this article ...

    • IPNV with high and low virulence: host immune responses and viral mutations during infection 

      Skjesol, Astrid; SkjÆveland, ingrid; Elnæs, Marianne; Timmerhaus, Gerrit Frantz; Fredriksen, Børge Nilsen; Jørgensen, Sven Martin; Krasnov, Aleksei; Jørgensen, Jorunn B (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Infectious pancreatic necrosis virus (IPNV) is an aquatic member of the Birnaviridae family that causes widespread disease in salmonids. IPNV is represented by multiple strains with markedly different virulence. Comparison of isolates reveals hyper variable regions (HVR), which are presumably associated with pathogenicity. However little is known about the rates and modes of sequence divergence and ...

    • Mapping uncertainties in the upstream : the case of PLGA Nanoparticles in Salmon Vaccines. 

      Nielsen, Kåre Nolde; Fredriksen, Børge Nilsen; Myhr, Anne Ingeborg (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      The diversity of nanotechnologies and of the governance challenges that their applications raise calls for exploration and learning across different cases. We present an Upstream Oversight Assessment (UOA) of expected benefits and potential harms of nanoparticles made of a synthetic polymer (PLGA) to improve vaccines for farmed salmon. Suggested by Jennifer Kuzma and colleagues, an UOA may help ...

    • Seasonal variability of meio- and macrobenthic standing stocks and diversity in an Arctic fjord (Adventfjorden, Spitsbergen) 

      Pawlowska, J.; Wlodarska-Kowalczuk, Maria; Zajaczkowski, Marek; Nygård, Henrik Andreas; Berge, Jørgen (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Strong environmental seasonality is a basic feature of the Arctic system, still there are few published records of the seasonal variability of the Arctic marine biota. This study examined the year-round seasonal changes of soft bottom macro- and meiobenthic standing stocks and diversity on a station located in an Arctic fjord (Adventfjorden, Spitsbergen). The seasonality observed in benthic biota ...
