    • Criteria for Safe Use of Plant Ingredients in Diets for Aquacultured Fish 

      Hemre, Gro-Ingun; Ringø, Einar; Amlund, Heidi; Aursand, Marit; Bakke-McKellep, Anne Marie; Olsen, Rolf Erik; Svihus, Birger (Research report; Forskningsrapport, 2009)
      A thorough review of different aspects on the health implications of using vegetable feed ingredients, both protein and lipid alternatives to fishmeal and fish oil, plus possible additions of immunostimulants, also including a short chapter on undesirable components, the use of genetically modified plants, and how processing may affect feed quality and availability, are given in the different chapters ...
    • Rekrutteringsutfordringer for marin sektor i framtida 

      Vik, Jostein; Johnsen, Jahn Petter; Sønvisen, Signe Annie (Journal article; Tidsskriftartikkel, 2009)
    • Power and the Production of Science. Assessing Cod Stocks as the Mechanistic Fishery Collapses 

      Sinclair, Peter R.; Johnsen, Jahn Petter; Ripley, Paul (Journal article; Tidsskriftartikkel; Peer reviewed, 2009)
      This paper discusses power relations in the production of knowledge claims and the validation of management strategies. The experience of doing stock assessment science and creating management plans for Canada’s east coast cod fishery illustrates this general process. We demonstrate that the cyborgization of fisheries-management is limited by its inability to produce power for stabilizing the ...
    • North Atlantic Fisheries in Change. From Organic Associations to Cybernetic Organizations 

      Johnsen, Jahn Petter; Murray, Grant Daniel; Neis, Barbara (Journal article; Tidsskriftartikkel; Peer reviewed, 2009)
    • The Cyborgization of the Fisheries : on Attempts to Make Fisheries Management Possible 

      Johnsen, Jahn Petter; Sinclair, Peter; Bavington, Dean; Holm, Petter (Journal article; Tidsskriftartikkel; Peer reviewed, 2009)
      Although natural resource exploitation has a long tradition, modern resource management is a more recent phenomenon. The huge variety in natural resource exploitation has made it difficult to place the industrial harvesting of marine living resources under political and managerial control. For most of history fish and fishing people have for all practical purposes been unmanageable. From the late ...
    • Nordic experience of fisheries management. Seen in relation to the reform of the EU Common Fisheries Policy. 

      Holm, Petter; Eliasen, Søren; Sverdrup-Jensen, Sten; Johnsen, Jahn Petter (Research report; Forskningsrapport, 2009)
      The waters surrounding the Nordic countries are rich in fish resources. Up to this date fisheries has been among the most important productive sectors in the Nordic economies, and in the Faroe Islands and Greenland it is by far the most important sector. Management of marine fisheries has over time had various objectives in the Nordic countries, ranging from fiscal and social purposes to stock ...
    • Fisheries rent creation and distribution – the imaginary case of Codland 

      Flåten, Ola (Conference object; Konferansebidrag, 2009-08-27)
      This paper discusses actual and possible achievements and failures of Codland and examines it from the point of view of efficiency and in terms of distribution. It is argued in favour of the joint analysis of the two approaches when contemplating fisheries management reforms, since such reforms may create both winners and losers. The analysis demonstrates how rent drain from fishing communities and ...
    • Effects of dietary soybean meal, inulin and oxytetracycline on gastrointestinal histological characteristics, distal intestine cell proliferation and intestinal microbiota in Atlantic salmon (Salmo salar L.) 

      Bakke-Mckellep, AM; Sperstad, Sigmund; Penn, MH; Salas, PM; Refstie, Ståle; Landsverk, Tor; Ringø, Einar; Krogdahl, Åshild (Journal article; Tidsskriftartikkel; Peer reviewed, 2007)
      Soyabean meal (SBM)-induced enteritis in the distal intestine of the teleost Atlantic salmon (Salmo salar L.) and other salmonids may be considered a model for diet-related mucosal disorders in other animals and man. The role of the intestinal microbiota in its pathogenesis was explored. Compared to diets containing fishmeal (FM) as the sole protein source, responses to extracted SBM or the prebiotic ...
    • Lokalsamfunnet – infrastruktur eller kulisse for fisketurisme? 

      Nordstrand, Kristin Berg; Johnsen, Jahn Petter (Chapter; Bokkapittel, 2008)
      Fisketurismen – nye aktører i kystsamfunn? Hvert år deltar flere tusen fiskere i vårtorskefisket utenfor Lofoten og Vesterålen. Når skreien kommer inn til kysten i januar/februar for å gyte, starter det årlige eventyret som kalles Lofotfisket. Fiskerne tar i løpet av noen måneder opp rundt 40 000 tonn fisk. Men det er ikke bare yrkesfiskerne som strømmer til området under sesongen. Også turistene ...
    • Forvaltning, styring og kybernetisering i fiske – konsekvenser for raudåtenæringa? 

      Johnsen, Jahn Petter (Chapter; Bokkapittel, 2008)
      Norsk fiskerinæring har gjennomgått betydelige teknologiske og organisatoriske endringer. Blant annet har de tidligere frie fiskeriene blitt lukket, og en rekke styrings- og reguleringssystemer er innført. Fra å være basert på uformell organisering og implisitt styring, fikk vi gjennom 1980- og 90-åra ei fiskerinæring som var gjenstand for eksplisitt styring. Etter tusenårsskiftet ser vi konturene ...
    • Petrodevelopment 2030: Socio-economic consequences of an extensive oil and gas development in the Barents Sea 

      Didyk, Vladimir; Arbo, Peter; Nilssen, Inge Berg; Hersoug, Bjørn; Nygaard, Vigdis; Sand, Jan Yngve; Østbye, Stein; Riabova, Larissa (Research report; Forskningsrapport, 2007-10)
      The theme of this report is the regional socio-economic consequences of an extensive oil and gas development in the Barents Sea. The regional focus area includes Finnmark County and Murmansk Oblast. The introductory chapter explains the purpose of the study and the way the work has been done. The next two chapters provide a detailed account of the region and its basic characteristics. The general ...
