PurposeResearch
ObjectivesObjectives

1.Routine daylight survey of the Rockall Plateau to assess the haddock stock within the 200 meter depth contour. Identify, quantify and record all other fish species encountered during the survey.
2.Opportunistic Habitat and Nephrops TV observation work on the plateau and flanks of Rockall bank to depths of 900 m using the drop frame.
3.Obtain temperature and salinity data from the surface and seabed at each trawling station using a Seabird 19+ CTD.
4.Identify, quantify and record all benthic invertebrate species caught.
5.Collect additional biological data on selected species for the DCF.

Narrative

Scotia sailed from Aberdeen at 1000 hours on Thursday 3 September stopping briefly at a trawling station northeast of Peterhead to test the performance of the fishing gear, Scanmar sensors and the CTD. Scotia then proceeded northwards to the Pentland Firth before heading west towards the Rockall Bank arriving at the first station ready to commence fishing operations at 1000hrs on Saturday 5 September. 5 stations were trawled successfully and without incident on the north side of the Bank. Moderate SW winds allowed good progress to made down the west side of the bank over the next couple of days with another 14 stations being completed before a deep area of low pressure arrived from the south and halted proceedings on Monday 7 September. Storm force winds were experienced throughout most of the morning with gusts of over 90 knots being recorded on more than one occasion. The wind moderated during the afternoon although the large swell meant that fishing was unable to resume until first light on the morning of the 9 September. The weather continued to improve with calm settled conditions being experienced for the remainder of the survey. This allowed the remainder of the fishing stations in the south as well as on the east side of the plateau to be completed successfully and the Rockall component of the survey concluded at midday on Saturday 12 September. In order to expand the bathymetric range of the survey three additional deeper stations were included in the survey on the south side of the Rockall Plateau. These stations were deeper than the 200m depth contour and yielded good catches of adult haddock.
