Results of investigations of migration pattern of artificially reared coastal cod (Gadus morhua L.) in western Norway
Svåsand, Terje; Godø, Olav Rune (ICES CM Documents;1987/F:26, Working paper, 1987)Investigations of the migration pattern have been a central part in an ongoing enhancement study of cod in western Norway. In Sept. - Nov. 1983, 20,947 juvenile, basin-reared cod fry were tagged and released at three sites ... -

Silent research vessels are not quiet
Ona, Egil; Godø, Olav Rune; Handegard, Nils Olav; Hjellvik, Vidar; Patel, Ruben; Pedersen, Geir (Journal article; Peer reviewed, 2007)Behavior of herring Clupea harengus stimulated by two ocean-going research vessels; respectively designed with and without regard to radiated-noise-standards. Both vessels generate a reaction pattern, but, contrary to ... -
Sjå havet med nye øyre : Seing the sea with sound
Godø, Olav Rune (Havforskningsnytt;Nr. 10 - 2010, Working paper, 2010)Whales have developed an advanced biological sonar system that they can use to communicate between continents. They also use their sonar when hunting prey, and once a delicacy has been located, they can catch them in the ... -
Spawning area and distribution of 0-group cod, Gadus morhua L., on the Møre coast. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
Godø, Olav Rune; Sunnanå, Knut (Fødevigen rapportserie, Conference object, 1984)This paper deals with the location of some major spawning grounds for cod, Gadus morhua L., on the Møre coast. The density distribution of adults prior to spawning and the 0-group fish later on was recorded. The two ... -

Studying the relationship between spatial fish distributions and trawl catches
Trenkel, Verena M.; Godø, Olav Rune; Handegard, Nils Olav; Patel, Ruben (ICES CM Documents;2004/R:26, Working paper, 2004)We propose an approach for studying the relationship between spatial fish distributions and the distribution of numbers in trawl catches. Individual spatial fish distributions are derived from acoustics data collected with ... -
Summer distribution and demography of Antarctic krill Euphausia superba Dana, 1852 (Euphausiacea) at the South Orkney Islands, 2011–2015
Krafft, Bjørn Arne; Knutson, T; Krag, Ludvig Ahm; Jensen, Knut Helge; Skaret, Georg; Krakstad, Jens-Otto; Larsen, Stuart; Melle, Webjørn Raunsgård; Iversen, Svein Arnholt; Godø, Olav Rune (Journal article; Peer reviewed, 2018)We carried out a survey of Antarctic krill (Euphausia superbaDana, 1850) from 2011 to 2015 to establish a long-term, time-series dataset of distribution, abundance, and demography for this species in the South Orkney Islands ... -
Swept area variation with depth and its influence on stratified trawl surveys indices on Arcto-Norwegian cod
Engås, Arill; Godø, Olav Rune (ICES CM Documents;1986/D:18, Working paper, 1986)Stratified trawl surveys have been carried out in the Barents Sea and the Svalbard areas since 1981. Based on the assumption of a constant area swept by the trawl during a standard trawl haul at any depth, swept area ... -
Tagging experiment results on cod in western Norway fjord areas
Godø, Olav Rune; Halland, Tor Ivar; Ågotnes, Per (ICES CM Documents;1986/G:80, Working paper, 1986)During recent years, experiments with large scale release of artificially produced Q-group cod at locations in western Norway waters have been carried out with the aim ofincreaseing the cod catches. As the general ... -
Testing acoustic platforms and methodology for observing marine ecosystem processes [1/10 - 20/10, 2006]
Johansen, Geir Odd; Godø, Olav Rune; Pedersen, Geir; Staurland Aarbakke, Ole Nicolai; Torkelsen, Terje; Totland, Atle ([Toktrapport/Havforskningsinstituttet];Nr. 10 - 2006, Working paper, 2006) -
Testing acoustic platforms and methodology for studying behaviour of demersal fish in a bottom trawl survey [19/9 - 10/10, 2005]
Godø, Olav Rune; Handegard, Nils Olav; Johansen, Geir Odd; Torkelsen, Terje; Totland, Atle; Pedersen, Ronald ([Toktrapport/Havforskningsinstituttet];Nr. 21 - 2005, Working paper, 2005) -
Testing various geostatistical models to combine bottom trawl catches and acoustic data
Bouleau, Mireille; Bez, Nicholas; Reid, David; Godø, Olav Rune; Gerritsen, Hans D. (ICES CM Documents;2004/R:28, Working paper, 2004)The aim of the CATEFA project is to combine information on demersal fish stock abundance from acoustic and bottom trawl surveys. While acoustic data are collected continuously while the research ship is underway, it is ... -
The effect of attenuation from Fish Shoals on long-range, wide-area acoustic sensing in the Ocean
Duane, Daniel; Cho, Byunggu; Jain, Ankita Deepak; Godø, Olav Rune; Makris, Nicholas C. (Journal article; Peer reviewed, 2019)Acoustics is the primary means of long-range and wide-area sensing in the ocean due to the severe attenuation of electromagnetic waves in seawater. While it is known that densely packed fish groups can attenuate acoustic ... -
The effect of different sweep lengths on length composition of bottom sampling trawl catches
Engås, Arill; Godø, Olav Rune (ICES CM Documents;1987/B:16, Working paper, 1987)Abundance estimates of North-east Arctic cod and haddock are given annually on the basis of combined bottom trawl and acoustic surveys.
