    • Functional diversity of the Barents Sea fish community 

      Wiedmann, Magnus Aune; Aschan, Michaela; Certain, Gregoire; Dolgov, Andrey V.; Greenacre, Michael; Johannesen, Edda; Planque, Benjamin; Primicerio, Raul (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
      This paper provides the first assessment of the functional diversity (FD) of the Barents Sea fish community. FD is recognized as an important driver of ecosystem functions and, thus, governs the adaptability of ecosystems in the face of disturbance. We integrate ecosystem survey data with an extensive trait matrix and show that fish FD displayed large spatial variation. The study period (2004 to ...
    • "Volstadsaken: Den «Høist Ærverdige Ret" 

      Ørebech, Peter (Chronicle; Kronikk, 2013)
      Det uklarhet mht. hva som egentlig er avgjort ved Volstad-dommen (Høyesteretts plenumsdom av 23 oktober 2013). Jeg skal i denne kronikk kort redegjøre for hva som er avgjort og hva dommen ikke tar stilling til.
    • Et delt mediemarked: Prosesser som fremmer små aviser 

      Holand, Astrid Marie (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Nord-Norge, Europas nordlige utkant, er en region kjennetegnet ved store avstander og spredt befolkning. Her ser det ut til at flere forhold sammen fremmer et desentralisert og superlokalt mediemarked. Økonomiske, politiske, teknologiske og sosiale faktorer peker i samme retning: Isteden for avisdød, ser vi mange nye småaviser. Spørsmålet blir da om denne «grasrotprosessen» er et svar på utfordringer ...
    • Nemo-effekten og koraller 

      Armstrong, Claire W.; Aanesen, Margrethe (Journal article; Tidsskriftartikkel, 2014-05-07)
      Bryr den norske befolkningen seg om dyphavet og de organismer som lever der selv om vi ikke har noen direkte nytte av dem? Er vi villig til å ofre økonomisk aktivitet som fiskeri og oljevirksomhet for beskytte miljøet i dyphavet? Vår studie sier ja.
    • The Backward-Bending Supply Curve in Fisheries-Revisited 

      Pham, Thanh Thuy; Flaaten, Ola (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      This study discusses and estimates the backward-bending supply curve, using data for three years over a six-year time span from the inshore purse seine fishery in Khanh Hoa province, Vietnam. Four different models are developed for estimation based on fisheries data, in the absence of stock survey data. The estimated maximum sustainable yield for the anchovy in south-central Vietnam ranges from ...
    • Marine protected areas in a welfare-based perspective 

      Reithe, Siv; Armstrong, Claire W.; Flaaten, Ola (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-05-04)
      Assuming a broad set of fisheries management goals, this paper analyzes the implementation of a marine protected area (MPA) together with open access outside, applying a bioeconomic model that ensures unchanged growth post-MPA. Taking into account that conservation and restoration, food security, employment and social surplus are amongst the objectives that many managers include in fisheries management, ...
    • Effekter av infeksjon med lakselus (Lepeophtheirus salmonis) på vill smolt av laks (Salmo salar L.) og ørret (Salmo trutta L.) 

      Andreassen, Kristoffer Berglund (Master thesis; Mastergradsoppgave, 2013-05-15)
      En metodikk for fangst, transport og gjennomføring av individforsøk på laboratoriet med naturlig lakselusinfisert vill smolt av laks og ørret ble utviklet. Effektene av luseinfeksjon ble deretter undersøkt på individnivå i to adskilte forsøk (ett med laksesmolt og ett med ørretsmolt). Her ble lusas effekt på fiskens vekst, appetitt, fysiologi og overlevelse undersøkt. Intensiteten av lus ble registrert ...
    • Induksjon av antivirale gener hos atlantisk laks (Salmo salar L.) ved intramuskulær injeksjon av ekspresjonsplasmid for interferon c (IFNc) 

      Robertsen, Camilla (Master thesis; Mastergradsoppgave, 2013-05-15)
      Virusinfeksjoner utgjør lakseoppdrettsnæringens største sykdomsproblem på landsbasis og forårsaker årlig store tap i form av dødelighet, redusert tilvekst, samt reduksjon i fiskehelse og - velferd. Dette til tross for omfattende smitteforebyggende tiltak og vaksinasjon. Interferonsystemet spiller en nøkkelrolle i det medfødte antivirale forsvaret hos pattedyr, hvor alarmproteinet interferon (IFN) ...
    • Antigen dose and humoral immune response correspond with protection for inactivated infectious pancreatic necrosis virus vaccines in Atlantic salmon (Salmo salar L) 

      Munang'andu, Hetron Mweemba; Fredriksen, Børge Nilsen; Mutoloki, Stephen; Dalmo, Roy Ambli; Evensen, Øystein (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      An enduring challenge in the vaccinology of infectious pancreatic necrosis virus (IPNV) is the lack of correlation between neutralizing antibodies and protection against mortality. To better understand the immunological basis of vaccine protection, an efficacy trial including Atlantic salmon (Salmo salar L.) vaccinated with a high antigen (HiAg) or low antigen (LoAg) dose vaccine was carried out ...
    • Quality of obstetric care in the sparsely populated sub-arctic area of Norway 2009-2011 

      Norum, Jan; Heyd, Anca Kriemhilde; Hjelseth, Bente; Svee, Tove Elisabeth; Mürer, Fred A; Erlandsen, Randi; Vonen, Barthold (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Background: It is challenging to obtain high quality obstetric care in a sparsely populated area. In the subarctic region of Norway, significant distances, weather conditions and seasonable darkness have called for a decentralized care model. We aimed to explore the quality of this care. Methods: A retrospective study employing data (2009–11) from the Medical Birth Registry of Norway was initiated. ...

    • Recruitment to the Norwegian fishing fleet: storylines, paradoxes, and pragmatism in Norwegian fisheries and recruitment policy 

      Sønvisen, Signe Annie (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      The majority of actors in the Norwegian fisheries consider recruitment of fishers to be the main future challenge for the Norwegian fishing fleet. As fleet recruitment is a highly politicized field, the problem of how to mitigate the recruitment problem is a subject of heavy debate. Some argue that recruitment problems are caused by low fleet profitability, while others argue that recruitment ...
    • Size selectivity of redfish (Sebastes spp.) in the Northeast Atlantic using grid-based selection systems for trawls 

      Herrmann, Bent; Sistiaga, Manu Berrondo; Larsen, Roger B.; Nielsen, Kåre Nolde (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Using experimental data and a model to predict size selection based on morphological data, we investigated size selection of redfish (Sebastes spp.) in the grid-based selection systems used in Northeast Atlantic trawls. We found that not all redfish make physical contact with the spacing between the bars in the sorting grids while they pass in the direction of the codend, and therefore the ...
    • 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 ...
    • 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 ...
    • Stakeholder Influence and Optimal Regulations: A Common-Agency Analysis of Ecosystem-Based Fisheries Regulations 

      Aanesen, Margrethe; Armstrong, Claire W. (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      One aspect of ecosystem-based management is to include new stakeholders. When an environmental NGO (ENGO) gets a say in the fisheries management, this will affect the authorities' optimal regulation. Combining a principal-agent model and a steady-state bioeconomic model, we show that under symmetric information the authorities will moderate their use of regulation as a response to the ENGO's increased ...
    • Pushed or pulled? Understanding fishery exit in a welfare society context 

      Johnsen, Jahn Petter; Vik, Jostein (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      For a long time the number of fishers in Norway has declined. Is the decline the result of an increasingly difficult situation for Norwegian fishers or can other factors have had an impact? Or in other words: are fishers pushed out or pulled out of the fisheries? Our analyses are based on a survey among retired fishers and suggest several reasons for exit: in addition to structural push and pull ...

    • Management and livelihood opportunity of Lake Tana fishery, Ethiopia 

      Chekol, Aytegeb Anteneh (Master thesis; Mastergradsoppgave, 2013-12-16)
      Agriculture plays vital role in Ethiopian economy. However, despite its importance and potential, the sector has remained at subsistence level. Animal protein is the most deficient nutrient in human diet. One of the traditional sources of animal protein of the developing world is through livestock rearing. Unfortunately, the livestock production is under increasing pressure from the combined effects ...
