FSP Western Edge ghost nets
One Fisheries Science Partnership survey was carried out in September/October 2005 to examine the amount and mesh size of lost and discarded gillnets in the anglerfish and shark fisheries on and around Rosemary Bank to the west of Scotland. Information from the DEEPNET1 project suggests that lost and discarded gill nets from these fisheries to the west of the British Isles may continue to “ghost fish” for long periods due to a slow rate of bio-fouling.

The stern trawler FV Kirkella was chartered to carry out a gillnet retrieval survey using the same gear as on Norwegian retrieval surveys for lost and discarded Greenland halibut gillnets. The area for the survey was chosen based on information on distribution of fishing activity from VMS data. Retrieval tows along transects were stratified by depth, the two strata corresponding to the depth range of the anglerfish (400 - 800m) and the deep-water shark (800 - 1200 m) fisheries. Mesh size was used to further attribute retrieved gear to fishery. The size and composition of any catches taken by retrieved nets were recorded. Heavy retrieval gear comprising a steel bar with three grappling anchors was used throughout the trip. This gear was attached to a steel warp and towed along the seabed at a speed of 1-2 knots (average 1.5 knots), a technique called ‘creeping’. The gear was hauled when the tension meters on the winch showed increased loading, indicating that the grappling anchors may have captured fishing gear. The gear and general method of deployment was exactly the same used on the annual Norwegian retrieval surveys for lost and discarded Greenland halibut gillnets.
