A stationary acoustic system for monitoring undisturbed and vessel affected fish behaviour
Godø, Olav Rune; Totland, Atle (ICES CM Documents;1996/B:12, Working paper, 1996)Thorough knowledge of the dynamics of natural fish behaviour and distribution within a survey and among surveys is fundamental for reliability of time series of abundance indices. Further, vessel/trawl affected avoidance ... -
Fish behaviour during sampling as observed from free floating buoys - application for bottom trawl survey assessment
Godø, Olav Rune; Somerton, David; Totland, Atle (ICES CM documents, Working paper, 1999)Varying fish distribution and behaviour during bottom trawl surveys has long been considered important for the reliability of survey abundance estimates. Size and species dependent behaviour may bias the estimates and ... -
Migratory behaviour of reared Norwegian coastal cod and north east Arctic cod
Godø, Olav Rune; Totland, Atle (ICES CM Documents;1995/G:11, Working paper, 1995)This paper is based on experiments to test if differences in migratory behaviour of Norwegian coastal cod and north east Arctic cod is related to parental origin or, alternatively, is related to the environmental experienced ... -
The use of transplantation-tagging-experiments in studies of migratory diversity of cod off Norway
Godø, Olav Rune; Korsbrekke, Knut; Soldal, Aud Vold; Totland, Atle (ICES CM Documents;1994/Mini:12, Working paper, 1994)Cod along the Norwegian coast show great variability in migration. Coastal Cod may be stationary for the whole life while mature Northeast Arctic Cod migrate long distances to reach the feeding areas in the Barents Sea ...
