    • 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 ...

    • Optical measurement of tissue perfusion changes as an alternative to electrocardiography for heart rate monitoring in Atlantic salmon (Salmo salar) 

      Svendsen, Eirik; Økland, Finn; Føre, Martin; Randeberg, Lise Lyngsnes; Finstad, Bengt; Olsen, Rolf Erik; Alfredsen, Jo Arve (Peer reviewed; Journal article, 2021)
      Background: Welfare challenges in salmon farming highlights the need to improve understanding of the fish’s response to its environment and rearing operations. This can be achieved by monitoring physiological responses ...

    • Redefining the oceanic distribution of Atlantic salmon 

      Rikardsen, Audun H.; Righton, David; Strøm, John Fredrik; Thorstad, Eva Bonsak; Gargan, Patrick G.; Sheehan, Timothy F.; Økland, Finn; Chittenden, Cedar; Hedger, Richard David; Næsje, Tor; Renkawitz, Mark; Sturlaugsson, Johannes; Caballero, Pablo; Baktoft, Henrik; Davidsen, Jan Grimsrud; Halttunen, Elina; Wright, Serena; Finstad, Bengt; Aarestrup, Kim (Peer reviewed; Journal article, 2021)
      Determining the mechanisms driving range-wide reductions in Atlantic salmon marine survival is hindered by an insufcient understanding of their oceanic ecology and distribution. We attached 204 pop-up satellite archival ...

    • 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 ...
