  • 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 (Springer, 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 ...
  • Experimental parameterisation of principal physics in buoyancy variations of marine teleost eggs 

    Jung, Kyung Mi; Folkvord, Arild; Kjesbu, Olav Sigurd; Sundby, Svein (Public Library of Science, 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 (Springer, 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 (Inter-Research, 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. ...
