    • Optimal response to lousy circumstances: The impact of salmon lice (Lepeophtheirus salmonis) on depth preference of sea trout (Salmo trutta) 

      Mohn, Agnes Marie (The University of Bergen, 2018-06-12)
      Sea trout are known for seeking out sources of freshwater to rid themselves of salmon lice. Still, the effect of natural haloclines in fjords on parasite dynamics is not well understood. We tagged 48 wild caught sea trout, ...

    • Ossification of Atlantic cod (Gadus morhua) – Developmental stages revisited 

      Sæle, Øystein; Haugen, Trine; Karlsen, Ørjan; van der Meeren, Terje; Bæverfjord, Grete; Hamre, Kristin; Rønnestad, Ivar; Moren, Mari; Lie, Kai Kristoffer (Elsevier, 2017-02)
      In studies of marine larvae, it is common to use days post-hatch as a developmental reference point. We show that age is a poor measure of morphological and physiological development in Atlantic cod. Therefore, we propose ...
