    • Balanced harvest: Utopia, failure, or a functional strategy? 

      Kolding, Jeppe; Garcia, Serge M.; Zhou, Shijie; Heino, Mikko Petteri (Peer reviewed; Journal article, 2016-04-21)
      Since “balanced harvest” was proposed in 2010 as a possible tool in the operationalization of the ecosystem approach to fisheries (EAF), the concept gained extensive international attention. Because maintaining ecosystem ...

    • Efficiency and catch dynamics of collapsible square and conical crab pots used in the red king crab (Paralithodes camtschaticus) fishery 

      Stiansen, Stian; Fernø, Anders; Furevik, Dag; Jørgensen, Terje; Løkkeborg, Svein (Peer reviewed; Journal article, 2008)
      We compared the capture efficiency and catch dynamics of collapsible square and conical pots used in resource assessment and harvesting of red king crabs (Paralithodes camtschaticus [Tilesius, 1815]) in the Barents Sea. ...

    • Opposite selection on behavioural types by active and passive fishing gears in a simulated guppy Poecilia reticulata fishery 

      Diaz Pauli, Beatriz; Wiech, Martin; Heino, Mikko Petteri; Utne-Palm, Anne Christine (Peer reviewed; Journal article, 2015-03)
      This study assessed whether fishing gear was selective on behavioural traits, such as boldness and activity, and how this was related with a productivity trait, growth. Female guppies Poecilia reticulata were screened for ...

    • Sustainable fishing of inland waters 

      Kolding, Jeppe; van Zwieten, Paul A.M. (Peer reviewed; Journal article, 2014-04-08)
      Sustainability in fisheries has over the past decades evolved from a single species maximization concept to covering ecosystem and biodiversity considerations. This expansion of the notion, together with increased evidence ...

    • Towards more efficient longline fisheries: fish feeding behaviour, bait characteristics and development of alternative baits 

      Løkkeborg, Svein; Siikavuopio, Sten Ivar; Humborstad, Odd Børre; Utne-Palm, Anne Christine; Ferter, Keno (Peer reviewed; Journal article, 2014-12)
      Better knowledge of food search behavior in fish is essential for studies that aim to improve longline fishing, particularly through bait development. This review provides an overview of our understanding of how fish detect ...

    • Trade-offs between growth and reproduction in wild Atlantic cod 

      Folkvord, Arild; Jørgensen, Christian; Korsbrekke, Knut; Nash, Richard David Marriott; Nilsen, Trygve; Skjæraasen, Jon Egil (Peer reviewed; Journal article, 2014-04-08)
      Animals partition and trade off their resources between competing needs such as growth, maintenance, and reproduction. Over a lifetime, allocation strategies should result in distinct trajectories for growth, survival, and ...

    • What can selection experiments teach us about fisheries-induced evolution? 

      Diaz Pauli, Beatriz; Heino, Mikko Petteri (Peer reviewed; Journal article, 2014-03)
      There is evidence that fisheries are altering the phenotypic composition of fish populations, often in ways that may reduce the value of fish stocks for the exploiters. Despite the increasing number of theoretical and field ...
