Using artificial neural networks to combine acoustic and trawl data in the Barents and North Seas
(ICES CM documents, Working paper, 2004)Groundfish have a wide and variable distribution making the use of trawling alone a highly inadequate sampling method. Trawl data provide species identification and numbers over a very small area and habitat type while ... -
Variabilities in stomach contents of cod, collected by demersal and pelagic trawl in the southern part of the Barents Sea
(ICES CM Documents;1990/G:3, Working paper, 1990)Samples of Northeast Arctic cod stomachs were collected separately on demersal and pelagic stations at the same date in February 1986 and were analysed for length group 30-40cm. The results indicate that the mean value ... -
Vertical entrance into a trawl of Barents Sea gadoids as studied with a two level fish trawl
(ICES CM Documents;1985/B:46, Working paper, 1985)Catch figures of different demersal species(cod, haddock, saithe etc.) in the cod-ends of a two level trawl were examined using variable height of the separating panel (0.5, 0.75, 1.0 and 1.5 m). Cod enters the trawl ... -
Vulnerability to predation of small cod (Gadus morhua) that escape from a trawl
(ICES CM Documents;1995/B:15, Working paper, 1995)Studies of the vulnerability to gear damage of fish that have been caught in a trawl but have escaped through the codend meshes have focussed on determining survival rates. This study examines the risk of predation in ...
