This survey was undertaken by Cefas as part of the North Sea Groundfish
Survey, Qtr 3 (FSS: IBTS3E; NSGFS);
75 core trawl stations are completed annually, to provide distribution and
stock composition estimates for fish species. Station, catch, length (all
species) and biological data (selected species) are collected using research
