    • CAGEREPORTER - Development of technology for autonomous, bio-interactive and high-quality data acquisition from aquaculture net cages 

      Kelasidi, Eleni; Su, Biao; Thorbjørnsen, Eirik Storås; Moen, Endre; Schellewald, Christian; Yip, Mau Hing; Remmen, Bjørnar Moe; Mulelid, Mats (Research report, 2020-03)
      The CageReporter project adapts the use of autonomous and tetherless underwater vehicles as a carrier of sensor systems for data acquisition, where the data are transferred from sea-based fish cages to a centralized land ...

    • Data capture and real-time data quality analysis 

      Kelasidi, Eleni; Schellewald, Christian; Yip, Mauhing; Remmen, Bjørnar Moe (SINTEF Ocean rapporter;OC2020 A-033, Research report, 2020)
      This report presents results obtained in the CageReporter project regarding the development of a 3D vision system to be used for data capture in fish cages. The developed system enables to obtain high-quality data with the ...

    • 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 ...

    • Hole Detection in Aquaculture Net Cages from Video Footage 

      Madshaven, Arild; Schellewald, Christian; Stahl, Annette (Peer reviewed; Journal article, 2022)

    • Identification of spectral signature for in situ real-time monitoring of smoltification 

      Svendsen, Eirik; Volent, Zsolt; Schellewald, Christian; Tsarau, Andrei; Bjorgan, Asgeir; Venås, Birger; Bloecher, Nina; Bondø, Morten Steen; Føre, Martin; Jónsdóttir, Kristbjörg Edda; Stefansson, Sigurd Olav (Peer reviewed; Journal article, 2021)
      We describe the use of an optical hyperspectral sensing technique to identify the smoltification status of Atlantic salmon (Salmo salar) based on spectral signatures, thus potentially providing smolt producers with an ...

    • Motion Trajectory Estimation of Salmon Using Stereo Vision 

      Nygård, Trym Anthonsen; Jahren, Jan Henrik; Schellewald, Christian; Stahl, Annette (Peer reviewed; Journal article, 2022)
      A main concern for the aquaculture industry is the fish behaviour and welfare. Motion trajectory analysis of salmon at aquaculture farming sites with respect to certain aquaculture operations aims to provide information ...

    • 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 ...

    • Vision-based pose estimation for autonomous operations in aquacultural fish farms 

      Schellewald, Christian; Stahl, Annette; Kelasidi, Eleni (Peer reviewed; Journal article, 2021)
      There is a largely increasing demand for the usage of Unmanned Underwater Vehicles (UUVs) including Remotely Operated Vehicles (ROVs) for underwater aquaculture operations thereby minimizing the risks for diving accidents ...
