    • Critical swimming speed in groups of Atlantic salmon Salmo salar 

      Remen, Mette; Solstorm, Frida; Bui, Samantha; Pascal, Klebert; Vågseth, Tone; Solstorm, David; Hvas, Malthe; Oppedal, Frode (Journal article; Peer reviewed, 2016-12-08)
      Critical swimming speed (Ucrit) has traditionally been measured in relatively small swimming tunnels with 1 fish alone. However, both increased flume lengths and swimming in groups are known to improve performance. Atlantic ...

    • Drag Forces and deformation of aquaculture cages – full-scale towing tests in the field 

      Gansel, Lars Christian; Oppedal, Frode; Birkevold, Jens; Tuene, Stig Atle (Journal article; Peer reviewed, 2018-02-23)
      Fish cages can experience strong loads due to hydrodynamic forces in the sea. Numerical models are often used to estimate drag forces on net cages, and the development and validation of such models is mostly based on ...

    • Fish welfare based classification method of ocean current speeds at aquaculture sites 

      Jónsdóttir, Kristbjörg Edda; Hvas, Malthe; Alfredsen, Jo Arve; Føre, Martin; Alver, Morten; Bjelland, Hans Vanhauwaert; Oppedal, Frode (Journal article; Peer reviewed, 2019-06-06)
      A major trend in marine aquaculture is to move production to more exposed sites with occasionally rough ocean current events. However, it is unclear whether fish will thrive in these extreme environments, since thorough ...

    • High host densities dilute sea lice Lepeophtheirus salmonis loads on individual Atlantic salmon, but do not reduce lice infection success 

      Samsing, Francisca; Oppedal, Frode; Johansson, David; Bui, Samantha; Dempster, Timothy David (Journal article; Peer reviewed, 2014)
      Host density likely plays a key role in host−parasite interactions, but empirical evidence in marine ecosystems remains limited. Classical models predict a positive relationship between host density and parasite infection ...

    • Novel tag-based method for measuring tailbeat frequency and variations in amplitude in fish 

      Warren-Myers, F.; Svendsen, Eirik; Føre, Martin; Folkedal, Ole; Oppedal, Frode; Hvas, Malthe (Peer reviewed; Journal article, 2023)
      The tailbeat frequency (TBF) together with tailbeat amplitude (TBA) of fish are tightly correlated with swimming speed. In addition, these parameters can be used as indicators of metabolic rate and general activity level, ...
