Measuring fishing effort is important for assessing the environmental sustainability of fish stocks and the socioeconomic efficiency of fishing activity. Fishing effort describes the amount of fishing gear used on a fishing ground over a given unit of time. Effort in this case is defined as number of creels hauled per day per 4 km2. This survey interviewed 198 creel vessel skippers from four regions, two on the west and two on the east coast of Scotland. This analysis has been produced from these SAMPLED vessels only. This IS NOT a census and IS NOT a map of all creeling effort in these waters or in the survey areas. This is an indication of potential fishing effort only and if creeling is not quantified in an area in this map, that DOES NOT mean creeling is not taking place. Equally quantified effort could be higher given some creeling vessels were not surveyed. Fishing effort outside of the surveyed area was not measured.
These layers are the outputs of research which developed a national river temperature model for Scotland capable of predicting both daily maximum river temperature and sensitivity to climate change. The layers show the following: summer_max_tw_2015_16 – Predictions of maximum daily river temperatures for the hottest day between July 2015 and June 2016. summer_max_tw_2003 – Predictions of maximum daily river temperatures for the hottest year in the last 20 years (2003). summer_climate_change_sensitivity – Predictions of the change in river temperature that would result from a 1°C increase in air temperature
Marine Scotland commissioned SNH to identify locations within inshore waters (6NM limit) where there is a need to consider additional management for bottom contacting mobile fishing gears to ensure there is no significant impact on the national status of 11 PMFs*. A consultation was launched in July 2018 seeking views on the data and evidence sources; the proposed management approach; and reasonable alternatives. The following data has been made available: point data for 10 PMF species and their management status (native oysters are excluded for sensitivity reasons); polygon extents of "areas for management consideration" and "knowledge gaps"; polygon extents of estimated fishing footprint of bottom trawl and scallop dredge for period 2009-2016; illustrative management areas for PMFs outside of the MPA network. *The PMFs encompassed by the review are Blue mussel beds, Cold water coral reefs, Fan mussel aggregations, Flame shell beds, Horse mussel beds, Maerl beds, Maerl or coarse shell gravel with burrowing sea cucumbers, Native oysters, Northern sea fan and sponge communities, Seagrass beds, Serpulid aggregations
Salmon Rivers in Scotland (2008) digital data produced by Scottish Government Marine Scotland Science with information from Fisheries Trusts and other sources.
High resolution bathymetry data of Rockall and Helen's Reef collected 2011-2012 as part of the ROAME Offshore Fisheries and Conservation (OFFCON) project. Rockall, a tiny island just 19 metres high, sits on the very extremity of Scotland’s marine environment. Some 180 miles due west of St. Kilda, it is buffeted year round by the extreme winds and swell that the North Atlantic weather generates. As such, it is Scotland’s only truly offshore shallow water ecosystem. The islet of Rockall is actually the only part of vast plateau of submerged continent that remains above sea-level.
