Description
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

vessels and GOV trawls. Benthic catches are also recorded. These annual
surveys (ongoing) are carried out in support of EU data regulations and as

collection of water temperature, salinity and litter data.
