• Environmental regulation of individual depth on a cod spawning ground 

      Meager, Justin J.; Skjæraasen, Jon Egil; Karlsen, Ørjan; Løkkeborg, Svein; Mayer, Ian; Michalsen, Kathrine; Nilsen, Trygve; Fernö, Anders (Journal article; Peer reviewed, 2012-12-13)
      Fine-scale characteristics of spawning grounds may provide the opportunity for cod Gadus morhua L. to regulate their external environment by adjusting their depth. Ultrasonic telemetry was used to study how the environment ...
    • Mating competition between farmed and wild cod Gadus morhua 

      Skjæraasen, Jon Egil; Meager, Justin J.; Karlsen, Ørjan; Mayer, Ian; Dahle, Geir; Rudolfsen, Geir; Fernö, Anders (Journal article; Peer reviewed, 2010-08-18)
      Increasing numbers of hatchery-produced fish entering marine environments has caused concern over potential fitness depressions in wild populations, yet no study has addressed the likelihood of hybridisation between farmed ...
    • Sperm characteristics and competitive ability in farmed and wild cod 

      Skjæraasen, Jon Egil; Mayer, Ian; Meager, Justin J.; Rudolfsen, Geir; Karlsen, Ørjan; Haugland, Thomas; Kleven, Oddmund (Journal article; Peer reviewed, 2009-01-27)
      The development of cod aquaculture has raised concerns about its effect on wild stocks. One risk is hybridisation between escapees and wild cod, causing genetic introgression, and, potentially, fitness depressions in wild ...
    • Vertical dynamics and reproductive behaviour of farmed and wild Atlantic cod Gadus morhua 

      Meager, Justin J.; Skjæraasen, Jon Egil; Fernö, Anders; Karlsen, Ørjan; Løkkeborg, Svein; Michalsen, Kathrine; Utskot, Stig Ove (Journal article; Peer reviewed, 2009-09-04)
      Rapid development of fish mariculture and efforts to restock depleted populations have raised concerns about the effects on wild populations and the risk of genetic introgression from hybridisation. Reproduction of many ...
