    • Heart rate and swimming activity as indicators of post-surgical recovery time of Atlantic salmon (Salmo salar) 

      Føre, Martin; Svendsen, Eirik; Økland, Finn; Gräns, Albin; Alfredsen, Jo Arve; Finstad, Bengt; Hedger, Richard David; Uglem, Ingebrigt (Peer reviewed; Journal article, 2021)
      Background Fish telemetry using electronic transmitter or data storage tags has become a common method for studying free-swimming fish both in the wild and in aquaculture. However, fish used in telemetry studies must be ...

    • Heart rate and swimming activity as stress indicators for Atlantic salmon (Salmo salar) 

      Svendsen, Eirik; Føre, Martin; Økland, Finn; Gräns, Albin; Hedger, Richard David; Alfredsen, Jo Arve; Uglem, Ingebrigt; Rosten, Carolyn; Frank, Kevin; Erikson, Ulf Gøran; Finstad, Bengt (Peer reviewed; Journal article, 2020)
      We investigated the relationship between telemetry measurements of heart rate and swimming activity and the physiological status in farmed Atlantic salmon (Salmo salar) to assess the potential to use telemetry measurements ...

    • Physiological constraints to climate warming in fish follow principles of plastic floors and concrete ceilings 

      Sandblom, Erik; Clark, Timothy; Gräns, Albin; Ekström, Andreas; Brijs, Jeroen; Sundström, Fredrik; Odelström, Anne; Adill, Anders; Teija, Aho; Jutfelt, Fredrik (Journal article; Peer reviewed, 2016-05-17)
      Understanding the resilience of aquatic ectothermic animals to climate warming has been hindered by the absence of experimental systems experiencing warming across relevant timescales (for example, decades). Here, we ...

    • Under the sea: How can we use heart rate and accelerometers to remotely assess fish welfare in salmon aquaculture? 

      Morgenroth, Daniel; Kvæstad, Bjarne; Økland, Finn; Finstad, Bengt; Olsen, Rolf-Erik; Svendsen, Eirik; Rosten, Carolyn; Axelsson, Michael; Bloecher, Nina; Føre, Martin; Gräns, Albin (Peer reviewed; Journal article, 2023)
      Recent advances in bio-sensing technologies open for new possibilities to monitor and safeguard the welfare of fishes in aquaculture. Yet before taken into practice, the applicability of all novel biosensors must be ...
