Sampling Atlantic salmon in the NE Atlantic during summer: methods of capture and distribution of catches
(ICES CM Documents;1996/M:12, Working paper, 1996)In July/ August 1991 the Institute of Marine Research (IMR, Norway) performed a pairtrawling (two boat trawl) experiment with a surface trawl to catch young herring in the northem Norwegian Sea. 34 postsmolts and two 1- ... -

Swept area variation with depth and its influence on stratified trawl surveys indices on Arcto-Norwegian cod
(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 ... -
