    • Observations of cod behaviour reveal insights into the function and properties of the swimbladder under pressure 

      Kooij, Jeroen van der; Righton, David; Michalsen, Kathrine; Thorsteinsson, Vilhjalmur; Svedäng, Henrik; Neat, Francis (ICES CM documents, Working paper, 2006)
      Atlantic cod (Gadus morhua L.) is a highly adaptive boreal species with a broad distribution through different ecosystems in the North Atlantic. Diet, environmental factors and population dynamics vary enormously ...
    • Quantifying the amount of fish unavailable to a bottom trawl by use of an upward looking transducer 

      Michalsen, Kathrine; Aglen, Asgeir; Somerton, David; Svellingen, Ingvald; Øvredal, Jan Tore (ICES CM documents, Working paper, 1999)
      When surveying demersal fish with a wide and variable vertical distribution, it is desirable to combine information from a bottom trawl survey with the information from a hydroacoustic survey into an absolute abundance ...
    • The use of data storage tags to study cod natural behaviour and availability to abundance surveys in the Barents Sea 

      Godø, Olav Rune; Michalsen, Kathrine (ICES CM Documents;1997/W:18, Working paper, 1997)
      Vertical movements of fish stocks can be studied by means of acoustic data from surveys, and diurnal related cycles in behaviour is often reported. To what extent the movements observed by this method reflect behaviour ...
    • Thermal dynamics of ovarian maturation in Atlantic cod (Gadus Morhua) 

      Kjesbu, Olav Sigurd; Righton, David; Krüger-Johnsen, Maria; Thorsen, Anders; Michalsen, Kathrine; Fonn, Merete; Witthames, Peter R. (Journal article; Peer reviewed, 2010-03)
      The timing and success of spawning in marine fish are of fundamental importance to population persistence and distribution and, for commercial species, sustainability. Their physiological processes of reproduction are ...
    • Thermal niche of Atlantic cod Gadus morhua: limits, tolerance and optima 

      Righton, David; Andersen, Ken Haste; Neat, Francis; Thorsteinsson, Vilhjalmur; Steingrund, P.; Svedäng, Henrik; Michalsen, Kathrine; Hinrichsen, Hans-Harald; Bendall, Victoria; Neuenfeldt, Stefan; Wright, Peter; Jonsson, Patrik; Huse, Geir; Kooij, Jeroen van der; Mosegaard, Henrik; Hüssy, Karin; Metcalfe, Julian D. (Journal article; Peer reviewed, 2010)
      Recent studies in the marine environment have suggested that the limited phenotypic plasticity of cold-adapted species such as Atlantic cod Gadus morhua L. will cause distributions to shift toward the poles in response to ...
