PurposeResearch
ObjectivesObjectives

1. Demersal trawling survey of the grounds off the north and west of Scotland in ICES Subarea VIa.
2. To obtain temperature and salinity data from the surface and seabed at each trawling station.
3. Collect additional biological data in connection with the EU Data Collection Framework (DCF).

Procedures

Loading of the trawl gear and scientific equipment will take place on 13 February with rigging and testing being completed on the same day. Scotia will then sail on the morning of 16 February. A training haul will be undertaken during the passage north to ensure all fishing gear/sensors are working effectively. Scotia will then commence fishing operations the next morning on predefined stations off the north Scottish coast and west of 4'W with weather conditions thereafter determining the route taken on the survey.

This is a random-stratified survey design with trawl stations being distributed within ten predefined strata covering the sampling area. 64 primary and 45 secondary stations have been generated. The intention is for 64 trawls to be undertaken on suitable ground as near to the specified primary sampling positions (Table 1) as is practicable, and where possible within a radius of 5 nautical miles of the sampling position. In the event that trawling is not possible within 5 nm of any primary station then the nearest appropriate secondary station will be used. Hauls will be of 30 minutes duration and in the main, fishing operations will be restricted to daylight hours between 0700 hours and 1800 hours, though exact start and finish times will vary slightly according to geographical location. The Scanmar system will be used to monitor the headline height, wing spread and door spread for each haul. Bottom contact data from each trawl will also be collected using the NOAA bottom contact sensor, which will be mounted on a bar in the centre of the ground-gear. In addition to the routine sampling, biological data will be collected for target species in line with the EU data regulation. All fish will be processed in accordance with Standing Instructions.

A CTD cast will be taken at each trawl station; in addition, the thermosalinograph will run continuously to obtain sea surface temperature and salinity throughout the survey area. Normal contact will be maintained with the Marine Laboratory.
