The standard survey has a total of approximately 100 tows or stations (75 are in ICES division VIId,25 are in ICES division Ivc). A commercial 4m beam trawl fitted with a chain mat, flip-up ropes, and a 40 mm cod-end liner is used.The gear is towed at 4 knots (ground speed) for 30 minutes on a warp length appropriate to the depth of water. At each sampling station (only daylight), all the fish species are sorted, weighed, counted and measured.
