• Evaluating acoustic-trawl survey strategies using an end-to-end ecosystem model 

      Holmin, Arne Johannes; Mousing, Erik Askov; Skogen, Morten D.; Hjøllo, Solfrid Sætre; Huse, Geir; Handegard, Nils Olav (Peer reviewed; Journal article, 2020)
      Fisheries independent surveys support science and fisheries assessments but are costly. Evaluating the efficacy of a survey before initiating it could save costs. We used the NORWECOM.E2E model to simulate Northeast Atlantic ...

    • PELFOSS (PELagic Fish Observation System Simulator) 

      Skogen, Morten D.; Handegard, Nils Olav; Holmin, Arne Johannes; Hjøllo, Solfrid Sætre; Mousing, Erik Askov; Utne, Kjell Rong; Vabø, Rune (Rapport fra havforskningen;30-2018, Research report, 2018)
      PELFOSS har utviklet en observasjonssystem-simulator for pelagisk fisk i Norskehavet. Simulatoren er en dataløype der romlig fordeling av fiskebestander fra en økosystemmodell er benyttet til å simulere ulike tokt. Disse ...
    • Simulations of multi-beam sonar echos from schooling individual fish in a quiet environment 

      Holmin, Arne Johannes; Handegard, Nils Olav; Korneliussen, Rolf J.; Tjøstheim, Dag (Journal article; Peer reviewed, 2012-12)
      A model is developed and demonstrated for simulating echosounder and sonar observations of fish schools with specified shapes and composed of individuals having specified target strengths and behaviors. The model emulates ...
