    • Timing and determination of potential fecundity in Atlantic cod (Gadus morhua) 

      Skjæraasen, Jon Egil; Nilsen, Trygve; Kjesbu, Olav Sigurd (Journal article; Peer reviewed, 2005)
      Studies using annual averages of lipid storage or estimated quality of the feeding season have shown that energy reserves influence egg production in Atlantic cod (Gadus morhua). However, vitellogenesis starts months ...

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

      Folkvord, Arild; Jørgensen, Christian; Korsbrekke, Knut; Nash, Richard D.M.; Nilsen, Trygve; Skjæraasen, Jon Egil (Journal article; Peer reviewed, 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 ...

    • Triploid Atlantic salmon and triploid Atlantic salmon × brown trout hybrids have better freshwater and early seawater growth than diploid counterparts 

      Fraser, Thomas; Lerøy, Hilde; Hansen, Tom Johnny; Skjæraasen, Jon Egil; Tronci, Valentina; Pinto Pedrosa, Cindy; Fjelldal, Per Gunnar; Nilsen, Tom Ole (Peer reviewed; Journal article, 2021)
      The use of reproductively sterile triploid salmonids would enhance the environmental sustainability of the aquaculture industry by preventing genetic exchange between escapees and wild conspecifics. To this end, we assessed ...

    • 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 ...
