• Divergent responses of Atlantic cod to ocean acidification and food limitation 

      Stiasny, Martina H.; Sswat, Michael; Mittermayer, Felix H.; Falk-Petersen, Inger-Britt; Schnell, Nalani K.; Puvanendran, Velmurugu; Mortensen, Atle; Reusch, Thorsten B.H.; Clemmesen, Catriona (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-20)
      In order to understand the effect of global change on marine fishes, it is imperative to quantify the effects on fundamental parameters such as survival and growth. Larval survival and recruitment of the Atlantic cod (<i>Gadus morhua</i>) was found to be heavily impaired by end‐of‐century levels of ocean acidification. Here, we analysed larval growth among 35‐36 days old surviving larvae, along with ...
    • 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 ...
    • Effects of chronic dietary petroleum exposure on reproductive development in polar cod (Boreogadus saida) 

      Bender, Morgan Lizabeth; Frantzen, Marianne; Vieweg, Ireen; Falk-Petersen, Inger-Britt; Johnsen, Helge Kreutzer; Rudolfsen, Geir; Tollefsen, Knut Erik; Dubourg, Paul; Nahrgang, Jasmine (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-10-04)
      Increasing human activities in the Arctic raise the risk of petroleum pollution, thus posing an elevated risk for Arctic organisms to be chronically exposed to petroleum compounds. The endocrine disrupting properties of some of these compounds (i.e. polycyclic aromatic hydrocarbons [PAHs]) present in crude oil may have negative effects on the long and energy intensive reproductive development of ...
    • Effects of parental acclimation and energy limitation in response to high CO2 exposure in Atlantic cod 

      Stiasny, Martina H.; Mittermayer, Felix H.; Göttler, Gwendolin; Bridges, Christopher R.; Falk-Petersen, Inger-Britt; Puvanendran, Velmurugu; Mortensen, Atle; Reusch, Thorsten B. H.; Clemmesen, Catriona M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-29)
      Ocean acidification (OA), the dissolution of excess anthropogenic carbon dioxide in ocean waters, is a potential stressor to many marine fish species. Whether species have the potential to acclimate and adapt to changes in the seawater carbonate chemistry is still largely unanswered. Simulation experiments across several generations are challenging for large commercially exploited species because ...
    • Growth and development of skeletal anomalies in diploid and triploid Atlantic salmon (Salmo salar) fed phosphorus-rich diets with fish meal and hydrolyzed fish protein 

      Peruzzi, Stefano; Puvanendran, Velmurugu; Riesen, Guido; Ripman Seim, Rudi; Hagen, Ørjan; Martínez-Llorens, Silvia; Falk-Petersen, Inger-Britt; Fernandes, Jorge Manuel de Oliveira; Jobling, Malcolm (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-22)
      Diploid and triploid Atlantic salmon, <i>Salmo salar</i> were fed high-protein, phosphorus-rich diets (56–60% protein; ca 18g phosphorus kg<sup>-1</sup> diet) whilst being reared at low temperature from start-feeding until parr-smolt transformation. Performances of salmon fed diets based on fish meal (STD) or a mix of fishmeal and hydrolysed fish proteins (HFM) as the major protein sources were ...
    • Transcriptome sequencing and histology reveal dosage compensation in the liver of triploid pre-smolt Atlantic salmon 

      Odei, Derrick Kwame; Hagen, Ørjan; Peruzzi, Stefano; Falk-Petersen, Inger-Britt; Fernandes, Jorge Manuel de Oliveira (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-08)
      Triploid Atlantic salmon (<i>Salmo salar</i> L.) is seen as one of the best solutions to solve key issues in the salmon farming industry, such as the impact of escapees on wild stocks and pre-harvest sexual maturation. However, the effects of triploidy on salmon smoltification are poorly understood at the molecular level, even though smoltification is a very sensitive period that has a major influence ...
