      A complex and dynamic community of microorganisms, play important roles within the fish gastrointestinal (GI) tract. Of the bacteria colonizing the GI tract, are lactic acid bacteria (LAB) generally considered as favorable microorganism due to their abilities to stimulating host GI development, digestive function, mucosal tolerance, stimulating immune response, and improved disease resistance. ...
    • Large-scale patterns in community structure of benthos and fish in the Barents Sea 

      Johannesen, Edda; Jørgensen, Lis Lindal; Fossheim, Maria; Primicerio, Raul; Greenacre, Michael; Ljubin, Pavel A.; Dolgov, Andrey V.; Ingvaldsen, Randi; Anisimova, Natalya A.; Manushin, Igor E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-04-23)
      Biogeographical patterns have an ecological basis, but few empirical studies possess the necessary scale and resolution relevant for investigation. The Barents Sea shelf provides an ideal study area, as it is a transition area between Atlantic and Arctic regions, and is sampled by a comprehensive survey of all major functional groups. We studied spatial variation in species composition of demersal ...

      Three wild-caught female harp seals (Pagophilus groenlandicus) from the Greenland Sea stock were brought into temporary captivity in connection with a controlled validation study on energetics. The two pups and one adult were kept in two indoor and outdoor experimental facilities approved by the Norwegian Animal Research Authority. They were trained daily using operant conditioning to participate ...
    • Local empowerment through the creation of coastal space? 

      Johnsen, Jahn Petter; Hersoug, Bjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
      Developments in national fisheries and marine environmental policies during the last 30 years have changed the relationship between coastal communities and the marine resources that people in these communities traditionally harvested. In Norway, for example, when the state authorities have made decisions to defend what they regard as national interests, the local level has been left with authority ...
    • 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 ...

    • Lumpsucker (Cyclopterus lumpus) otoliths: dissection, mounting and age-reading 

      Albert, Ole Thomas; Bertelsen, Bernt; Jonsson, Sigurd T.; Pettersen, Ivar H.; Torstensen, Else (Research report; Forskningsrapport, 2000-05)
      A workshop was held at Institute of Marine Research, Flødevigen Marine Research Station, Arendal, Norway, 17-19 February 1999, to investigate methodes for age-determination of lumpsucker (Cyclopterus lumpus) from otoliths. The report summarises the results from the workshop and some subsequent analyses. The otoliths are very small and special training is necessary to locate them. The zonation pattern ...
    • 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 ...
    • Making the Arctic predictable: The changing information infrastructure of Arctic weather and sea ice services 

      Knol, Maaike; Arbo, Peter; Duske, Paula; Gerland, Sebastian; Lamers, Machiel; Pavlova, Olga; Sivle, Anders Doksæter; Tronstad, Stein (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-19)
      This paper explores the changing infrastructure around weather and sea ice information provisioning for Arctic marine areas. Traditionally, the most important providers of operational information on sea ice and weather conditions are the national sea ice and meteorological services. More recently, the community of Arctic information providers has become more heterogeneous with the establishment of ...
    • 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 ...
    • The marine biodiscovery pipeline and ocean medicines of tomorrow 

      Jaspars, Marcel; de Pascale, Donatella; Andersen, Jeannette Hammer; Reyes, Fernando; Crawford, Alex D.; Ianora, Adrianna (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-01-01)
      Marine organisms possess the capacity to produce a variety of unique and biologically potent natural products for treating human diseases, many of which are currently commercially available or are in advanced clinical trials. Here we provide a short review on progress in the field and discuss a case study of an EU-funded project, PharmaSea, which aims to discover novel products for the treatment of ...
    • 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, ...
    • Marine reserve creation and interactions between fisheries and capture-based aquaculture: A bio-economic model analysis 

      Bui, Bich Xuan; Armstrong, Claire W. (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-12-12)
      The rapid growth of aquaculture affects wild fisheries in several ways. We present a bioeconomic model of the interaction between a commercial wild fishery and capture-based aquaculture that depends on harvest of wild juveniles. We assume that aquaculture reduces the intrinsic growth rate of the wild fish stock due to wild caught juveniles used as seeds, influencing wild stock size and commercial ...
    • 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 ...
    • Maximum Yield Fishing and Optimal Fleet Composition. A Stage Structured Model Analysis With an Example From the Norwegian North-East Arctic Cod Fishery 

      Helgesen, Irmelin Slettemoen; Skonhoft, Anders; Eide, Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-01)
      A stage structured fishery model with three stages; recruits, immature fish and mature fish is formulated and utilized to analyse maximum sustainable yield (MSY) and optimal harvesting composition in a fishery with two heterogeneous fleets. The stage structured model developed bundles the age classes found in age structured models into stage classes based on their level of maturity, but also the ...

    • Mechanistic model identifies increasing light availability due to sea ice reductions as cause for increasing macroalgae cover in the Arctic 

      Scherrer, Kim Josefin Niklasdotter; Kortsch, Susanne; Varpe, Øystein; Weyhenmeyer, Gesa Antonie; Gulliksen, Bjørn; Primicerio, Raul (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-04)
      In the Arctic, rising seawater temperatures and increasing underwater light caused by reductions in sea ice cover are expected to change the structure of arctic marine communities. Substantial, sometimes sudden, increases in macroalgal productivity and biomass have already been observed in arctic rocky bottom communities. These macroalgal responses have been attributed to increasing temperature and ...
    • Med lov og skjønn skal kysten forvaltes 

      Solås, Ann-Magnhild; Johnsen, Jahn Petter (Research report; Forskningsrapport, 2014)
      Gjennomgangen av lov- og regelverket viser at det skal ivareta mange hensyn. Lov- og regelverket er komplekst og følgelig vil også beslutningsprosessene være preget av denne kompleksiteten. De ulike lovene og forskriftene, og de bestemmelsene i hver enkelt lov og forskrift søker å ivareta både politiske, administrative og faglige hensyn. De forvaltes også på ulike politiske og administrative ...
