1. To assess the fishing performance, in terms of gear geometry, of the BT237 with different sweepline lengths. Either 15 or 20 minute hauls will be made using Scanmar and bottom contact sensor on water depths ranging from 30 m to approximately 200 m. 2. To carry out catch comparison trials to compare the fishing performances of the BT237 trawl against the standard survey trawl BT137 (GOV) rigged with A gear. 3. To obtain underwater observations of net shape (BT237) using a self-recording mini TV system attached to different areas of the trawl. Procedures The fishing gear will be loaded aboard on 22 October with only the BT237 trawl rigged onto the lower drum with 47 m sweeps and 40 m bridles. The 68 m sweeps and 50 m bridles will be rigged onto the top drum and operated similar to the BT137 (GOV) during west coast surveys. The polyvalent doors will be used with both trawls throughout the survey, spare set to be 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 a shakedown haul will be made. Thereafter and weather permitting the intention is to work around the Shetland Islands for the duration of the survey. Trawling operations will be conducted from 0700 until 2100. After assessing the different sweep lengths the BT137 (GOV) will be rigged onto the top drum and catch comparison hauls will be made comparing BT237 v BT137 (GOV). |
