| Objectives and Narrative |
Rockall Haddock Survey
FRS Objectives 1. Routine daylight survey of the Rockall Plateau to assess the haddock stock within the 200 metre contour. Identify, quantify and record all other fish species encountered during the survey. 2. Nephrops TV observation work along the East edge of the bank to depths of 500 metres. 3. Identify, quantify and record all benthic invertebrate species caught. 4. Obtain temperature and salinity data from the surface and seabed at each trawling station. 5. Collect additional biological data in connection with the EU Data Directive 1639/2001. PU/JNCC Objectives 1. Opportunistic use of the drop frame and to contribute to mapping distribution of Annex I reef habitat as required under the EC Habitats Directive. 2. Collection of invertebrate fauna from trawl samples. Narrative Scotia sailed from Aberdeen at 1000 on Wednesday 5 September stopping briefly at a trawling station between Aberdeen and Peterhead to test the performance of the fishing gear. Scotia then proceeded to the Rockall plateau arriving at the first station ready to commence fishing operations at 0600 on the 7 September. Trawling continued during daylight hours for the next 6 days without interruption. In line with the WTD 6-7 hauls were completed within the 13 hour working day. The haddock survey was completed by 1700 on the 13 September. Scotia then steamed east - a westerly gale preventing any further drop frame deployments - towards St Kilda so that the vessel could switch doors and change fishing gear in readiness for the deepwater survey on the shelf edge. Scotia arrived in Village Bay off St Kilda on the 14 September where the gear changes were made. Prior to the weather deteriorating the 2000kg trawl doors were dropped into position in readiness for deepwater fishing. |
