1. To carry out a groundfish survey of the North Sea as part of the ICES coordinated IBTS, using a standard GOV trawl in order to obtain information on: a) Distribution, size composition and abundance of all fish species caught. b) Age - length distribution of selected species. c) Distribution of fish in relation to their environment. d) Distribution of macrobenthos and anthropogenic debris. e) Surface and bottom temperature and salinity data using SAIV miniCTD. f) Length weight & maturity information using individual fish measurements, in support of the EU Data Regulation. 2. Post-mortum changes to length of dogfish 3. Collection of 0-group cod (frozen) 4. Collection of following species - various sizes 9 of each species (frozen) Callionymus lyra: Dragonnet Clupea harengus harengus: Atlantic herring Gadus morhua: Atlantic Cod Trisopterus luscus: Pouting Microstomus kitt: Lemon sole Ammodytes marinus: Lesser sandeel Trachurus trachurus: Atlantic horse mackerel 5.

Onboard were 7 Cefas fisheries staff, and 1 student from the University of Southampton. Before work on the primary stations commenced, a 'shakedown' tow was carried out to allow for the deployment of the gear, to check that all sensors were working correctly and to allow scientists and crew to familiarise themselves with their particular work areas. A standard station consisted of a cast with a CTD and a 10-litre Niskin bottle, followed by a 30-minute tow with the standard IBTS rigged GOV, with a miniCTD attached. At the start of the survey, on every station, fisheries acoustic data were continuously collected at three operating freque |
