    • Determining spatial feed distribution in sea cage aquaculture using an aerial camera platform 

      Lien, Andreas Myskja; Schellewald, Christian; Stahl, Annette; Frank, Kevin; Skøien, Kristoffer Rist; Tjølsen, Jan Inge (Journal article; Peer reviewed, 2019-11)
      Within this paper we describe an unmanned aerial vehicle (UAV) based method to estimate the spatial feed pellet distribution in salmon fish-cages and exploit it within a case study to determine the radial pellet distribution ...

    • Feed intake in Atlantic salmon fed with or without surface spreading of feed 

      Aas, Turid Synnøve; Ytrestøyl, Trine; Åsgård, Torbjørn Einar; Skøien, Kristoffer Rist; Alver, Morten Omholt; Alfredsen, Jo Arve (Journal article, 2020)
      In intensive salmon farming, it is common practice to spread the feed over a large surface area, assuming that spreading of the feed increases feed intake in the fish. However, the impact on the feed pellets during spreading ...

    • Modelling and simulation of rotary feed spreaders with application to sea cage aquaculture ? A study of common and alternative designs 

      Skøien, Kristoffer Rist; Alver, Morten; Alfredsen, Jo Arve (Journal article; Peer reviewed, 2018-08)
      Rotary feed spreaders are extensively used in large scale fish aquaculture and are tasked with distributing pelletized feed in a spatially uniform manner over the water surface. Questions have been raised with respect to ...

    • Precision fish farming: A new framework to improve production in aquaculture 

      Føre, Martin; Frank, Kevin; Norton, Tomas; Svendsen, Eirik; Alfredsen, Jo Arve; Dempster, Timothy David; Eguiraun, Harkaitz; Watson, Win; Stahl, Annette; Sunde, Leif Magne; Schellewald, Christian; Skøien, Kristoffer Rist; Alver, Morten; Berckmans, Daniel (Journal article; Peer reviewed, 2017-11-14)
      Aquaculture production of finfish has seen rapid growth in production volume and economic yield over the last decades, and is today a key provider of seafood. As the scale of production increases, so does the likelihood ...
