    • Density-dependent growth as a key mechanism in the regulation of sh populations: evidence from among-population comparisons 

      Lorenzen, Kai; Enberg, Katja (Journal article; Peer reviewed, 2001-11-30)
      It is generally assumed that fish populations are regulated primarily in the juvenile (pre-recruit) phase of the life cycle, although density dependence in growth and reproductive parameters within the recruited phase has ...

    • Development of ten microsatellite loci in the marine fish ling (Molva molva) 

      Ring, Anne-Karin; Knutsen, Halvor; Fiani, David; Hoelzel, Rus; André, Carl (Journal article; Peer reviewed, 2009-09)
      We developed primers for two dinucleotide and eight tetranucleotide microsatellite loci in a marine fish, the ling (Molva molva). All markers were obtained from partial genomic DNA libraries and characterized in 55 unrelated ...

    • Do accurate stock estimates increase harvest and reduce variability in fisheries yields? 

      Myrseth, Johanna; Enberg, Katja; Heino, Mikko; Fiksen, Øyvind (Journal article; Peer reviewed, 2011-03-22)
      Fisheries managers normally make decisions based on stock abundance estimates subject to process, observation, and model uncertainties. Considerable effort is invested in gathering information about stock size to decrease ...

    • Does size matter? A bioeconomic perspective on optimal harvesting when price is size-dependent 

      Zimmermann, Fabian; Heino, Mikko; Steinshamn, Stein Ivar (Journal article; Peer reviewed, 2011-09-09)
      Body size is a key parameter influencing demographic characteristics of fish populations as well as market value of landed catch. Yet in bioeconomic modelling, body size is often an overlooked biological and economic ...

    • Effects of Fishing Tourism in a Coastal Municipality: a Case Study from Risør, Norway 

      Moksness, Erlend; Gjøsæter, Jakob; Lagaillarde, Guillaume; Mikkelsen, Eirik; Olsen, Esben Moland; Sandersen, Håkan T.; Vølstad, Jon Helge (Journal article; Peer reviewed, 2011)
      Recreational fishing has become an important part of the Norwegian tourist industry. The coastal municipality of Risør, southern Norway, is considering further development of its marine fishing tourism to increase local ...

    • Evolutionary principles and their practical application

(Journal article; Peer reviewed, 2011-02-17)
      Evolutionary principles are now routinely incorporated into medicine and agriculture. Examples include the design of treatments that slow the evolution of resistance by weeds, pests, and pathogens, and the design of breeding ...
