1. To assess the fishing performance, in terms of gear geometry, of the BT237 trawl with new Thyboron trawl doors to configure correct warp/depth ratios. Either 15 or 20 minute hauls will be made using Scanmar and bottom contact sensor in water depths ranging from 30 m to approximately 500 m. 2. To assess the effect on gear geometry and ground gear contact of adding additional weight to BT237 light hopper rig and reducing the length of the headline extension chains. 3. To obtain underwater observations of net shape (BT237) and door performance using a self-recording mini TV system attached to different areas of the trawl. 4. To assess the performance of the GOV trawl with the new Thyboron trawl doors. Procedures All fishing gear will be loaded aboard on 22 October with the BT237 trawl rigged onto the lower drum and GOV rigged onto the top drum. The Thyboron Type 11 trawl doors will be used first and the GOV polyvalent doors stored on the upper castles. Scotia will sail on 25 October and after all safety drills have been competed, make passage for the Moray Firth where trials will commence to evaluate the performance of the Thyboron trawl doors. Thereafter, and weather permitting the intention is to work around the Shetland Islands for the duration of the survey with trawling operations conducted between 07:00 and 19:00 hours Survey schedule and operations will be decided by SIC after daily consultation with Captain and Fishing Master. During the survey one member of scientific staff will undergo Scientist in Charge Training (SIT). |
