This information feeds directly into the stock assessments used for national and international management of Scottish salmon both through the construction of stock recruitment relationships and estimation of egg deposition. Sampling of individuals can also provide information on their condition, while examination of scale samples allows their growth history to be investigated. Together with data on salmon catches and counts, these sampling records underpin adult salmon stock assessment in Scotland.\u003C\/p\u003E\n","url":"https:\/\/data.marine.gov.scot\/dataset\/adult-atlantic-salmon-age-and-length-sampling-records","state":"Active","private":true,"revision_timestamp":"Thu, 02\/19\/2026 - 13:54","metadata_created":"Thu, 02\/19\/2026 - 13:30","metadata_modified":"Thu, 02\/19\/2026 - 13:54","creator_user_id":"ef1d5231-9817-4ea3-875e-aadc55addee0","type":"Dataset","resources":[{"id":"ee9f5114-0400-4839-8b25-361c41bff16f","revision_id":"","url":"https:\/\/data.marine.gov.scot\/sites\/default\/files\/\/salmon_ages_sizes_doi.csv","description":"\u003Cp\u003EThe file is structure with the following column,format, and description\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003Eriver\u003C\/strong\u003E\u003Cbr \/\u003E\nFormat: character\u003Cbr \/\u003E\nDescription: Salmon river (Scotland)\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003Ecapture\u003C\/strong\u003E\u003Cbr \/\u003E\nFormat: character - categories\u003Cbr \/\u003E\nDescription: Capture type: \u0027rod\u0027 or \u0027trap or net\u0027\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003Edate\u003C\/strong\u003E\u003Cbr \/\u003E\nFormat: date (yyyy-mm-ddThh:mm:ss)\u003Cbr \/\u003E\nDescription: Sampling date\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003Esea_age\u003C\/strong\u003E\u003Cbr \/\u003E\nFormat: character - categories\u003Cbr \/\u003E\nDesctiption: Sea age at return to river (years): one sea-winter (1SW), two sea-winter (2SW) or three sea-winter (3SW)\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003Esmolt_age\u003C\/strong\u003E\u003Cbr \/\u003E\nFormat: character - categories\u003Cbr \/\u003E\nDescription: Age at river emigration: one year (S1), two years (S2), three years (S3), or four years (S4)\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003Elength\u003C\/strong\u003E\u003Cbr \/\u003E\nFormat: numeric (2 decimal places)\u003Cbr \/\u003E\nDescription: Length at return to river in cm\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003Eweight\u003C\/strong\u003E\u003Cbr \/\u003E\nFormat: numeric (2 decimal places)\u003Cbr \/\u003E\nDescription: Weight at return to river in kg\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003Edata_provider\u003C\/strong\u003E\u003Cbr \/\u003E\nFormat: character\u003Cbr \/\u003E\nDescription: Origin of sample collection\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003Esal_hab_km\u003C\/strong\u003E\u003Cbr \/\u003E\nFormat: numeric\u003Cbr \/\u003E\nDescription: Estimated length of river (km) classified as salmon habitat (calculated following Gardiner and Egglishaw 1986; MacLean et al. 2007)\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003Eregion\u003C\/strong\u003E\u003Cbr \/\u003E\nFormat: character\u003Cbr \/\u003E\nDescription: Salmon Fishery Statistical Region\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003Elat\u003C\/strong\u003E\u003Cbr \/\u003E\nFormat: numeric (decimal degrees)\u003Cbr \/\u003E\nDescription: Latitude of river outflow\u003C\/p\u003E\n","format":"csv","state":"Active","revision_timestamp":"Thu, 02\/19\/2026 - 13:54","name":"Adult Atlantic salmon age and length - sampling records data","mimetype":"text\/csv","size":"24.71 MB","created":"Thu, 02\/19\/2026 - 13:44","resource_group_id":"31be76ba-0c93-4b89-92cd-afa54780775d","last_modified":"Date changed  Thu, 02\/19\/2026 - 13:54"}],"tags":[{"id":"4f6ab1e2-5570-4ecd-86b2-4118655e451d","vocabulary_id":"2","name":"fish"},{"id":"8045c8ed-8547-452b-bc6d-8142bc42c624","vocabulary_id":"2","name":"fisheries"}],"groups":[{"description":"\u003Cp\u003EData and reports from the Freshwater Laboratory in Marine Directorate.\u003C\/p\u003E\n","id":"31be76ba-0c93-4b89-92cd-afa54780775d","image_display_url":"https:\/\/data.marine.gov.scot\/sites\/default\/files\/\/button%20220i-16.png","title":"Freshwater","name":"group\/freshwater"}]}]}
