• High fish density delays wound healing in Atlantic salmon (Salmo salar) 

      Sveen, Lene Rydal; Timmerhaus, Gerrit; Krasnov, Aleksei; Takle, Harald; Stefansson, Sigurd Olav; Handeland, Sigurd O; Ytteborg, Elisabeth (Peer reviewed; Journal article, 2018-11-15)
      In this study, we look closer at how high fish densities influence wound repair mechanisms in post-smolt Atlantic salmon. The fish were wounded with a 5 mm skin punch biopsy needle and stocked at two different densities, ...
    • Hypoxia tolerance and responses to hypoxic stress during heart and skeletal muscle inflammation in Atlantic salmon (Salmo salar) 

      Lund, Morten; Dahle, Maria Krudtaa; Timmerhaus, Gerrit; Alarcon, Marta; Powell, Mark; Aspehaug, Vidar; Rimstad, Espen; Jørgensen, Sven Martin (Peer reviewed; Journal article, 2017-07-11)
      Heart and skeletal muscle inflammation (HSMI) is associated with Piscine orthoreovirus (PRV) infection and is an important disease in Atlantic salmon (Salmo salar) aquaculture. Since PRV infects erythrocytes and farmed ...
    • Impact of fish density and specific water flow on skin properties in Atlantic salmon (Salmo salar L.) post-smolts 

      Sveen, Lene Rydal; Timmerhaus, Gerrit; Torgersen, Jacob Seilø; Ytteborg, Elisabeth; Jørgensen, Sven Martin; Handeland, Sigurd Olav; Stefansson, Sigurd Olav; Nilsen, Tom Ole; Calabrese, Sara; Ebbesson, Lars O.E.; Terjesen, Bendik Fyhn; Takle, Harald Rune (Peer reviewed; Journal article, 2016)
      Prolonged production of Atlantic salmon (Salmo salar) post-smolts in closed-containment systems has prompted research into biological requirements under higher production intensities. This study examined the effect of fish ...
    • Morphomolecular alterations in the skin mucosa of Atlantic salmon (Salmo salar) after exposure to peracetic acid-based disinfectant 

      Lazado, Carlo C.; Haddeland, Sindre; Timmerhaus, Gerrit; Berg, Ragnhild Stenberg; Merkin, Grigory; Pittman, Karin; Pedersen, Lars-Flemming (Journal article; Peer reviewed, 2020)
      Peroxygen-based chemotherapeutants are commonly used in treating ectoparasitic infections in fish. A majority of relevant studies address the effects of these substances on the targeted causative agents, but little is known ...
    • Performance and welfare of Atlantic salmon, Salmo salar L. post-smolts in recirculating aquaculture systems: Importance of salinity and water velocity 

      Ytrestøyl, Trine; Takle, Harald Rune; Kolarevic, Jelena; Calabrese, Sara; Timmerhaus, Gerrit; Rosseland, Bjørn Olav; Teien, Hans-Christian; Nilsen, Tom Ole; Handeland, Sigurd O; Stefansson, Sigurd; Ebbesson, Lars; Terjesen, Bendik Fyhn (Journal article; Peer reviewed, 2020)
      Producing a larger post‐smolt in recirculating aquaculture systems (RAS) could shorten the production time in sea cages and potentially reduce mortality. Knowledge of the biological requirements of post‐smolts in ...
    • Wound healing in post-smolt Atlantic salmon (Salmo salar L.) 

      Sveen, Lene Rydal; Timmerhaus, Gerrit; Krasnov, Aleksei; Takle, Harald; Handeland, Sigurd; Ytteborg, Elisabeth (Peer reviewed; Journal article, 2019-03-05)
      Skin biopsies (5 mm) taken from behind the dorsal fin on Atlantic salmon post-smolts were followed over a 2 month period. The healing process was dominated by hemostasis, acute inflammation, and epidermal repair the first ...
