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 ... -
Experimental study of installation procedure and volume estimation of tarpaulin for chemical treatment of fish in floating cages
Volent, Zsolt; Birkevold, Jens; Stahl, Annette; Lien, Andreas Myskja; Sunde, Leif Magne; Lader, Pål Furset (Journal article; Peer reviewed, 2017)In the salmon industry chemical delousing is done by enclosing the cage in a tarpaulin, and then mixing the chemical agent in the enclosed water volume. Correct dosage is important to obtain the wanted effect, and in order ... -

Modellforsøk med dukbasert avlusing Beskrivelse av gjennomføringen av modellforsøk i Hirtshals - Foreløpig rapport
Volent, Zsolt; Birkevold, Jens; Stahl, Annette (SINTEF Fiskeri og havbruk;A26406, Research report, 2014-10-23)Det er avgjørende å ha god kontroll på volumet under en avlusing, for å kunne beregne innblanding av lusemidler, slik at en oppnår ønsket behandlingskonsentrasjon. En for høy konsentrasjon kan skade fisken, og for lav ... -
Modellforsøk med dukbasert avlusing. Beskrivelse av gjennomføringen og resultater fra modellforsøk i Hirtshals, juni 2014 for FHF
Volent, Zsolt; Birkevold, Jens; Stahl, Annette; Lien, Andreas Myskja; Sunde, Leif Magne (SINTEF Fiskeri og Havbruk reports;A26728, Research report, 2014-10-23)Målet for prosjektet var å kartlegge og demonstrere i modellskala hvordan de forskjellige dukfasonger oppførte seg ved utsett ved forskjellige strømhastigheter, og om det var mulig å fylle dukene 100 % ved bruk av forskjellige ... -
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 ...
