    • Effect of incubation temperature on eggs and larvae of lumpfish (Cyclopterus lumpus) 

      Imsland, Albert; Danielsen, Mathias; Jonassen, Thor Magne; Hangstad, Thor Arne; Falk-Petersen, Inger-Britt (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-24)
      Two batches of lumpfish eggs were incubated at three temperature regimes; 1-Ambient seawater 4–6 °C (cold), 2-Ambient seawater for 10 days followed by a gradual increase to 10 °C (gradient), 3-Constant 10 °C seawater (warm). The eggs incubated in cold water had the highest egg mortality (38.5% ± 15.7) and lowest hatching success (46.1% ± 7.2), while the gradient group regime showed highest hatching ...

    • Effect of incubation temperature on eggs and larvae of lumpsucker (Cyclopterus lumpus L.) 

      Danielsen, Mathias (Master thesis; Mastergradsoppgave, 2016-08-22)
      In this study the aim was to investigate how incubation temperature effected lumpsucker eggs and larvae; by comparing early cell symmetry, egg/embryo development, mortality, hatching success and early larvae size weight and histomorphology. Two batches of eggs were incubated at 3 temperature regimes; 1- Ambient seawater 4-6°C (cold), 2-Ambient seawater for 10 days then gradually increased to ...
