ObjectivesObjectives

1. Demersal trawling survey of the grounds off the north and west coast of Scotland.

2. Collect abundance data on pre-metamorphosed herring larvae using the 2-meter circular framed methot net.

3. To obtain temperature and salinity data from the surface and seabed at each trawling station.

4. Identify, quantify and record all benthic species caught.

5. Collect additional biological data in connection with the EU Data Directive 1639/2001 and 1581/2004.

Narrative

Scotia sailed from Aberdeen at 1030hrs on 9 March. A familiarisation haul was completed successfully on a clear tow east of Peterhead at the Buchan Deeps with the fishing gear and scanmar sensors performing well.

With favourable weather conditions, Scotia then made passage north and arrived at the first methot station west of Orkney at 3am on 10 March. This was completed successfully but yielded no herring larvae. In addition, 2 calibration tows were completed in order to test the efficiency of the flow meter. Fishing operations commenced on station 5 at 0630 the same day also west of Orkney.

During the next 4 days despite periods of rough weather Scotia proceeded west and north successfully completing the fishing and methot stations in the northern most part of the survey area albeit with 2 consecutive foul hauls (stations 35 and 311) where the belly was torn out. Improved weather conditions allowed Scotia to complete the fishing stations west of the Hebrides successfully although significant damage was sustained to the gear on two occasions and another haul was declared foul due to the sheer weight of mackerel caught in the net. On this occasion, it was estimated that over 20 tons of mackerel were present in the net. Such was the weight of the catch that Scotia was unable to pull the bag up the trawl ramp and in the end had to slip the catch.
