UK-level utilisation distributions (UD) for Razorbill. UDs are provided in a sequence of 5% contours for each species starting at the 5% utilisation distribution and ending at the 95% utilisation distributions. Within the ecological literature the 95% UD is often used to define the 95% home range of a species and the 50% UD is used to define the 50% core range of a species.
The 21 Scottish marine regions and offshore marine regions are used for state of the sea assessments. These areas consolidate the existing statutory Scottish Marine Regions with non-statutory offshore marine regions. For the purposes of assessment, the offshore marine regions extend to the continental shelf limits (adjacent to Scotland)
Scottish Marine Regions (FishDAC_1609) and Scottish Sea Areas (FishDAC_12184) were merged. The sea area boundaries were adjusted in places to better fit with SMRs. Offshore marine regions were renamed to avoid confusion with the Scottish sea areas. All changes were approved by the Scottish Seas Data and Assessment Group (SSDAG)
Direct employment in fishing, fish processing and aquaculture activities by travel to work areas (TTWA, 2011 versions) as a % of total employment in Scotland. Percentage value is most recent year (year also recorded as attribute), with a graph image in attributes showing trend from 2015 onwards. All statistics from ONS / Nomis.
For assessment purposes, the Scottish creel fishing grounds are divided into 12 assessment areas. Some Scottish assessment areas extend outside Scottish Territorial Waters. On the east of Scotland the South East assessment area extends beyond the Scottish border, while on the west coast, the Clyde assessment area stops short of the Irish border. There is some fishing on grounds outside the assessment areas. Currently these areas support only small fisheries and landings data are monitored for any change in importance.
Derived from Thomas, H.J., 1958. Lobster and crab fisheries in Scotland. Marine Research, 8: 107 and subsequently revised to include two offshore areas – Papa, which lies to the west of Shetland, and Sule, which is to the north and west of Orkney and includes Rona, Sulisker and Sule-Skerry banks.
