| Objectives | Objectives
1. To carry out comparative fishing trials using different ground gear configurations on the BT137 GOV trawl. 2. To record all gear geometry using Scanmar, bottom contact sensors and load cells. 3. To work up all catches as per standing IBTS instructions. Narrative Scotia sailed from Aberdeen at 1230 hours on 16 May and immediately carried out test tows of both gears (GOV BT137 with 'C' & 'D' ground gears) in Aberdeen Bay. These were completed successfully and the vessel then proceeded to the Rockall Bank to carry out the main trials. Scotia arrived at Rockall at around 0500 hours on 18 May. The initial four tows at two locations were carried out to decide on a 30 or 15 minute tow duration. Catch rates indicated that a 30 minute tow was appropriate, and this was used thereafter. The vessel than continued to fish following the experimental programme designed for this survey. This entailed carrying out two tows at each station. Paired tows were either with the same gear to quantify the disturbance effect, or with the two gears sequentially to quantify the gear effect. Tow locations were taken from previous Rockall surveys. Ten tows were carried out per day over a 10 day period Trials were completed at 1130 hours on 28 May, after which the vessel proceeded to Aberdeen, arriving at approximately 0000 hours on 30 May. |
