      Heino, Mikko; Godø, Olav Rune; Dieckmann, Ulf (ICES CM documents;2010/M:24, Working paper, 2010)
      Over the last eight decades, northeast Arctic cod has shown a marked change towards earlier maturation at smaller sizes. At the same time, harvesting shifted from primarily targeting mature cod in the spawning grounds to ...

    • Impact of size-selective mortality on waterfleas (Daphnia) 

      Wathne, Ingrid; Jensen, Knut Helge; Enberg, Katja; Heino, Mikko (ICES CM Documents;2010/M:25, Working paper, 2010)
      Size‐selective predation shapes species and induces changes in life‐history traits. Exposure to sizeselective mortality will make being the size that is vulnerable dangerous and possibly fatal; thus, if small individuals ...

    • Pigmentation of salmonids: Factors affecting carotenoid deposition in rainbow trout (Salmo gairdneri) 

      Torrissen, Ole (ICES CM Documents;1984/F:23, Working paper, 1984)
      Factors affecting carotenoid deposition in rainbow trout (Salmo gairdneri) were investigated in three feeding experiments. The deposition of astaxanthin in the flesh increased significantly with increasing levels of ...
