  • Building fisheries institutions through collective action in Norway 

    Jentoft, Svein; Finstad, Bjørn-Petter (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-16)
    Institutions, and the collective action that created them and which they enable, can play an important role in poverty eradication. In Norway, the Raw Fish Act passed in 1938 in the aftermath of the international financial crisis that hit the fishing industry hard, and the fishers’ cooperative sales-organizations that it authorized testify to this. Most of all, they helped to empower fishers in their ...
  • Synergy as strategy: learning from La Restinga, Canary Islands 

    Pascual-Fernández, José J.; De la Cruz Modino, Raquel; Chuenpagdee, Ratana; Jentoft, Svein (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-29)
    In this paper, we draw attention to the role of synergies in marine conservation and community sustainability. Using marine protected areas (MPAs) as examples, we argue that MPAs that are carefully designed to fit the existing social systems can be instrumental in synergy building and fostering community development. Such synergy creation is an essential governance strategy that helps enhance ...

    The marine environment is a rich source of biodiversity, including microorganisms that have proven to be prolific producers of bioactive secondary metabolites. Arctic seas are less explored than warmer, more accessible areas, providing a promising starting point to search for novel bioactive compounds. In the present work, an Arctic marine Pseudomonas sp. belonging to the Pseudomonas (P.) fluorescence ...
  • Influence of soak time on catch performance of commercial creels targeting Norway lobster (Nephrops norvegicus) in the Mediterranean Sea 

    Brčić, Jure; Herrmann, Bent; Mašanović, Marina; Šifner, Svjetlana Krstulović; Škeljo, Frane (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-13)
    Creel catch performance is known to be affected by the soak time in many fisheries. If creels maintained their efficiency over longer periods, increase in soak time should lead to proportional increase in catch quantity. However, the exact shape of this relationship is unknown for creel fisheries targeting Norway lobster (Nephrops norvegicus). If it was known fishermen could adjust their fishing ...
