Salmon Stock Assessment Areas boundaries, used by Scottish Government Marine Scotland 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. Salmon Stock Assessment Areas are also used for reporting annual statistics obtained from salmon catch returns made by the owners, occupiers and agents of salmon fisheries. See links on the Statistical boundaries page for more information on the annual assessment, river grades and salmon stock management.  Salmon Stock Assessment Areas are a subset of Scottish rivers, where there is 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. There are 173 Salmon Stock Assessment Areas (SSAA), made up of 215 individual or grouped rivers, 17 of which are Special Areas of Conservation (SAC) for Atlantic salmon. See information on the map layer fields below. Salmon Stock Assessment Areas boundaries were derived by Scottish Government Marine Scotland from Scottish Environment Protection Agency (SEPA) 1:50,000 river catchment boundaries, based on 1:50,000 DTM data from the Institute of Hydrology (now the Centre for Ecology and Hydrology). For SAC rivers, the outflow boundaries include information from Scottish Natural Heritage (SNH) (now NatureScot) and the Joint Nature Conservation Committee (JNCC). * Please Note * This layer was derived by the Scottish Government from a licensed dataset.
