Fish were caught both using a fine mesh- shrimp trawl, which was pulled for 15 minutes at a speed of 2-3 knots. The research vessel (the Luctor) followed the depth contourlines during each transect as to maintain a constant fisshing dept.
Some of the data from 2005 were caught by the commercial fisshing vessel the GO58. In 2005 fykes were used to capture migratory fish.
