Metadata: Area Management - Salmon Stock Assessment Areas
Abstract:
Salmon Stock Assessment Areas boundaries, used by Scottish Government to demarcate rivers where salmon stocks are assessed under the Salmon Conservation (Scotland) Regulations 2016. The regulations are amended annually to introduce measures for protecting stocks. Assessment Areas are also used for reporting annual statistics obtained from salmon catch returns made by the owners/occupiers/agents of salmon fisheries. Assessment Areas boundaries are based on Scottish Environment Protection Agency (SEPA) river catchments and licensed Centre for Ecology and Hydrology (CEH) 1:50,000 data. For 17 salmon Special Areas of Conservation (SAC) the Assessment Areas boundaries include information from Scottish Natural Heritage (SNH) (now NatureScot) and the Joint Nature Conservation Committee (JNCC). Assessment Areas boundaries are a subset of Scottish river catchments, where Marine Scotland has sufficient information on salmon stocks in rivers, or groups of rivers, that their status can be assessed annually and graded for the subsequent fishing season. Assessment Areas boundaries were updated in 2019 and and remained unchanged until the assessment for the 2025 season. Three assessment areas were removed due to lack of salmon fishing data, reducing the total number of areas from 215 to 212. Attributes include annual grade values from 2018 onwards. Salmon Stock Assessment Areas are available to view as a layer on the Marine Directorate Open Data Network – see marine.gov.scot pages for Salmon and Sea Trout Fishing at https://marine.gov.scot/themes/salmon-sea-trout-fishing. Boundaries were re-projected from British National Grid (BNG) to WGS84 Web Mercator before upload to NMPi. As the layer was derived by the Scottish Government from a licensed dataset, it is not downloadable or routinely available. It can be shared on request if the user provides evidence that they hold a licence from the Centre for Ecology and Hydrology (CEH) for the 1:50,000 Digital Terrain Model (DTM). Information on river grades for salmon fishing can be found at: https://www.gov.scot/publications/salmon-fishing-final-river-gradings/

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Salmon Stock Assessment Areas boundaries were derived by Scottish Government from 1:50,000 river catchment boundaries which were created by the Scottish Environment Protection Agency (SEPA) from the Institute of Hydrology (now the Centre for Environment and Hydrology (CEH)) 1:50,000 Digital Terrain Model (DTM) data. Assessment Areas boundaries were created as a subset of Scottish river catchments with coastal outflow locations at Normal Tide Limit (NTL). For 17 salmon Special Areas of Conservation (SACs), outflow locations were adjusted to match SAC boundaries from Scottish Natural Heritage (SNH) (now NatureScot) and for the River Tweed SAC, in part from the Joint Nature Conservation Committee (JNCC). The 1:50,000 scale of Salmon Stock Assessment Areas boundaries means that they are suitable for mapping but may not be sufficiently accurate to produce exact selections from, or overlaps with, other datasets. Maps containing Salmon Stock Assessment Areas boundaries require Crown copyright and acknowledgement of SEPA and CEH, while data from NatureScot and JNCC require an Open Government Licence statement: 'Assessment Areas boundaries derived from the Scottish Environment Protection Agency (SEPA) 1:50,000 river catchment data, based on digital spatial data licensed from the Centre for Ecology and Hydrology, © NERC (CEH)' (preceded if appropriate by 'Some features of this map are'); and 'Contains Ordnance Survey data © Crown copyright and database right [year]'; and ‘Contains public sector information licensed under the Open Government Licence v3.0’ |
