• Egg buoyancy variability in local populations of Atlantic cod (Gadus morhua) 

      Jung, Kyung-Mi; Folkvord, Arild; Kjesbu, Olav Sigurd; Agnalt, Ann Lisbeth; Thorsen, Anders; Sundby, Svein (Peer reviewed; Journal article, 2012)
      Previous studies have found strong evidences for Atlantic cod (Gadus morhua) egg retention in fjords, which are caused by the combination of vertical salinity structure, estuarine circulation, and egg specific gravity, ...
    • Experimental parameterisation of principal physics in buoyancy variations of marine teleost eggs 

      Jung, Kyung Mi; Folkvord, Arild; Kjesbu, Olav Sigurd; Sundby, Svein (Peer reviewed; Journal article, 2014-08-14)
      It is generally accepted that the high buoyancy of pelagic marine eggs is due to substantial influx of water across the cell membrane just before ovulation. Here we further develop the theoretical basis by applying laboratory ...
    • Sexual dimorphism of drumming muscles in European hake (Merluccius merluccius) 

      Groison, Anne-Laure; Kjesbu, Olav Sigurd; Suquet, Marc (Peer reviewed; Journal article, 2010)
      Dissections of mature and non-mature European hake males and females (N = 142) collected in waters off the western coast of Norway and in the Bay of Biscay (France) in 2004–2006 demonstrate for the first time that this ...
    • Skipped spawning in Northeast Arctic haddock Melanogrammus aeglefinus 

      Skjæraasen, Jon Egil; Korsbrekke, Knut; Nilsen, Trygve; Fonn, Merete; Kjesbu, Olav Sigurd; Dingsør, Gjert Endre; Nash, Richard David Marriott (Peer reviewed; Journal article, 2015-04-22)
      Large interannual fluctuations in the numbers of offspring joining a teleost population are common, yet factors affecting offspring production, a key driver of fish population size and demography, are often poorly understood. ...
