    • A contribution to the economics of multispecies harvesting with special attention to the Barents Sea fisheries 

      Flåten, Ola (Doctoral thesis; Doktorgradsavhandling, 1990)

    • Some methodological issues in economic evaluation in health care 

      Olsen, Jan Abel (Doctoral thesis; Doktorgradsavhandling, 1993)
    • Sjarkfiske og ressursforvaltning 

      Maurstad, Anita (Doctoral thesis; Doktorgradsavhandling, 1997-11-07)
      <p>Med utgangspunkt i feltarbeid fra fiskevær i Troms, samt intervjuer med flere fiskere i Troms og Finnmark, drøfter jeg det nordnorske sjarkfisket i lys av to motstridende teorier om ressurshøsting og -regulering. Den ene sier at små enheter er mer ressursvennlige enn store. I småskalaproduksjon finnes innebygde begrensninger i produksjonsmåten, dels fordi vi står ovenfor husholdsbasert produksjon ...
    • Dendroclimatology on Scots pine (Pinus sylvestris L.) in northern Norway 

      Kirchhefer, Andreas Joachim (Doctoral thesis; Doktorgradsavhandling, 2000-03-17)
      A total of ten tree-ring chronologies of Scots pine, Pinus sylvestris L., was constructed between the Vesterålen archipelago and the Finnmarksvidda in order to investigate the regional variability of radial growth and climate response of pine. The longest tree-ring chronology, located in Forfjorddalen in Vesterålen, was highly significant back to AD 1354. The study area was divided into three ...
    • Understanding and practising market orientation : exploring how managers cope in turbulent environments 

      Ottesen, Geir Grundvåg (Doctoral thesis; Doktorgradsavhandling, 2001-11-23)
      Ottesens doktorgrad fokuserer på hva det innebærer å være markedsorientert for bedrifter i fiskerinæringen. I næringsmessige debatter blir det ofte påpekt at norsk fiskeindustri må bli mer markedsorientert. Mens begrepet markedsorientering har blitt et moteord som brukes av både politikere og næringsliv, blir det sjelden klargjort hva dette innebærer. Resultatene fra avhandlingen avdekker hvordan ...
    • Fiskeren som forsvant? En studie av avfolking, overbefolking og endringsprosesser i norsk fiskerinæring 

      Johnsen, Jahn Petter (Doctoral thesis; Doktorgradsavhandling, 2003-02-28)
      Hva er en fisker? Dette er det sentrale spørsmålet i denne avhandlinga. Spørsmålet er utgangspunkt for å utforske endringsprosesser i fiskerinæringa, både i fortida og i samtida. På bakgrunn av dette drøfter avhandlinga hvilke oppfatninger, forståelser og beskrivelser som til enhver tid benyttes til å definere hva fiskere er i ulike sammenhenger. Undersøkelsen starter i det som kan kalles ...
    • The effects of behaviour on the acoustic target strength of capelin (Mallotus villosus) and implications for acoustic abundance estimation 

      Jørgensen, Roar (Doctoral thesis; Doktorgradsavhandling, 2004)
      The general objective of this thesis was to collect improved knowledge about the target strength (TS) of capelin (Mallotus villosus) through experimental studies, as well as to undertake adequate observations of behaviour of capelin during surveying situations, including the effect of different depth distributions and of vessel avoidance. Pre- and post-spawning capelin from the Balsfjord and the ...
    • Quality of salted cod (Gadus morhua L.) as influenced by raw material and salt composition 

      Lauritzsen, Kristin (Doctoral thesis; Doktorgradsavhandling, 2004-03-29)
      Hva påvirker kvaliteten på saltfisk? Saltfiskens lukt, farge, konsistens og smak bestemmer kvaliteten. Dersom torsken blir dødsstiv samtidig med at saltet strømmer inn i fiskekjøttet, oppnår man et lavere vektutbytte, vann- og saltinnhold på sluttproduktet. Fisken bør derfor saltes etter dødsstivheten for å oppnå et høyt vektutbytte. Ønsker man å minimere proteintapet fra salteprosessen og få en høy ...
    • Upstream vertical integration and financial performance : the case of the Norwegian fish processing industry 

      Isaksen, John R. (Doctoral thesis; Doktorgradsavhandling, 2007-06-08)
      In this thesis, four different articles address the correlation between vertical integration and profitability in the Norwegian fish processing industry. By vertical integration we mean the ownership and control of one firm over different stages in the value chain. Firms within this industry consider the uncertain supply of fish as a main challenge. Literature prescribes vertical integration as an ...
    • Effect of viral RNA mimics and ISA virus infection on expression of key genes of the Atlantic salmon interferon system 

      Kileng, Øyvind (Doctoral thesis; Doktorgradsavhandling, 2008)
      We have studied the innate immune responses of Atlantic salmon and how this responds to stimulation and infection by the aquatic orthomyxovirus Infectious salmon anemia virus (ISAV). This work has focused on the Type I interferon (IFN) system which is critically important in the vertebrate immune response against viral infections. As a part of this work we have studied the Atlantic salmon IFN ...
    • Economic analyses of user interactions in the coastal zone 

      Mikkelsen, Eirik (Doctoral thesis; Doktorgradsavhandling, 2008-05-05)
      Marine and coastal areas contain many resource types, with many uses and user groups. Conflicts are common, both over access to the same resource, and to avoid negative effects of others’ use. Such conflicts are expected to increase in extent and severity. Being able to analyze and understand the nature and consequences of the interactions between different user groups, how it affects their behaviour ...
    • Information in financial markets : how private information affects prices, how it can be revealed and how it may be used 

      Sirnes, Espen (Doctoral thesis; Doktorgradsavhandling, 2008-06-06)
      The literature on financial markets is vast and it is probably safe to say that all tools in the economists’ tool case have been applied to this field. In this dissertation I will present three papers that are very diverse in their approach to the subject of finance, but have an important common theme; asymmetric information and efficiency in financial markets.
    • Animal-habitat relationships in high altitude rangelands 

      Singh, Navinder J. (Doctoral thesis; Doktorgradsavhandling, 2008-09-18)
      This study conducted in the high altitude rangelands of Indian Transhimalaya, deals with basic questions regarding the ecology of an endangered species, the wildsheep Tibetan argali (Ovis ammon hodgsoni) and applied issues related to its conservation and potential conflict with the local nomadic pastoralists. The basic questions on ecology are aimed at delineating the habitat and resource selection ...
    • A bioeconomic perspective on the Norwegian Barents Sea cod fishery 

      Eide, Arne (Doctoral thesis; Doktorgradsavhandling, 2008-11-14)
    • Boundary construction in mandated science : the case of ICES' advice on fisheries management 

      Nolde Nielsen, Kåre (Doctoral thesis; Doktorgradsavhandling, 2008-11-21)
      What is the relationship between science and politics? What should it be? How are their respective roles conceived and acted out in practice? Should science and politics be clearly separated? How? Are there cases in which they can be usefully mixed? What cases are those, and are there some ways of mixing that are better than others? This project explores such questions by examining relationships ...
    • Risk sensitive reproductive strategies : the effect of environmental unpredictability 

      Bårdsen, Bård-Jørgen (Doctoral thesis; Doktorgradsavhandling, 2009-02-13)
      A crucial task in ecology is to quantify trade offs between competing demographic processes for experienced by individuals that inhabit unpredictable environments. Perhaps the most widely studied trade off is that between current reproduction and future survival (‘the cost of reproduction’). While experimental studies have been widely used to quantify life history strategies in birds, virtually ...
    • Arctic charr (Salvelinus alpinus (L.)), an adequate host to Gyrodactylus salaris (Monogenea) 

      Winger, Anja Celine (Doctoral thesis; Doktorgradsavhandling, 2009-05-26)
      Arctic charr is a suitable host to Gyrodactylus salaris, and G. salaris is a non-pathogen to this host species. This parasite is highly pathogenic to Norwegian Atlantic salmon and it has driven most affected salmon populations to extinction. In Troms County in northern Norway, two rivers are infected. These two rivers, Skibotnelva and Signaldalselva, are the northernmost G. salaris infected rivers ...
