  • Skildring:CRIMAC survey with G.O.Sars, 2022.11.27-2022.12.03. From Tromsø and Kvænangen to Lofoten, Vestrålen and Myre. We test new ideas and methods in using scientific echosounders and sonars to study fish. We study herring in Kvænangen fjord with broadband echosounders pointing downwards and sideways to port and starboard. We test and measure the size of fish directly from echosounder data. We test various aspects of broadband echosounder use on fish aggregations. We travel to Lofoten/Vestrålen to aid

  • Skildring:One of five scientific echosounders (orange thingy is the antenna/transducer) ready to go down to 25m depth. This is a gimbaled transducer arrangement for vertically upwards orientation of the acoustic beams. Installed under salmon net pen, looking through and up. Broadband and narrowband acoustic echo observations of individual fishes.Lovely fieldwork in Matre Research Station last week for CRIMAC project. Some net pens with salmon are now equipped like RV G.O.Sars, that is with full research v

  • Skildring:20210920 CRIMAC associated master student Cecilie Skaale (sup. Tonje Forland) got help from expert acousticians Egil Ona, Tonje Forland, Antonio, and Rokas to set up her experiment in Matre. Broadband echo-sounders are used in Matre to study the behavior of salmon in net pens with and without sea lice prevention measures - restricted access to surface waters coupled with submerged air-filled dome or walled tube to sea surface for swim-bladder inflation.
