Here we present recapture data from monitored smolt releases on four Scottish rivers and compare return rates of hatchery and wild-reared salmon smolts originating from a common stock on two of these rivers. Rod recapture rates from stocked hatchery smolts ranged from 0-0.23%. In comparative tests return rates for wild-reared fish were on average ten times greater than those for stocked fish (range 6 to 13-fold where at least one reared fish returned). Given the relatively poor returns and associated production costs any benefit to fisheries of stocking with hatchery-reared smolts is unlikely to be sustainable in the Scottish context. Furthermore, risks of adverse genetic effects should be considered.\u003C\/p\u003E\n","url":"https:\/\/data.marine.gov.scot\/dataset\/ranching-rod-evaluation-adult-returns-hatchery-reared-atlantic-salmon-smolts-released","state":"Active","log_message":"Update to resource \u0027Property title\u0027","private":true,"revision_timestamp":"Tue, 01\/07\/2020 - 18:22","metadata_created":"Fri, 05\/15\/2015 - 09:59","metadata_modified":"Tue, 01\/07\/2020 - 18:22","creator_user_id":"30436a8d-34e8-47d5-b586-8a555ab42696","type":"Dataset","resources":[{"id":"9e4170df-524f-4fee-a368-29c4d6fee885","revision_id":"","url":"http:\/\/www.scotland.gov.uk\/Resource\/0047\/00476498.pdf","description":"","format":"pdf","state":"Active","revision_timestamp":"Tue, 01\/07\/2020 - 14:53","name":"Scottish Marine and Freshwater Science Vol 6 No 5","mimetype":"pdf","size":"","created":"Fri, 05\/15\/2015 - 10:00","resource_group_id":"d0fc86dc-1394-43d4-aef1-c8cf5ac500f9","last_modified":"Date changed  Tue, 01\/07\/2020 - 14:53"}],"tags":[{"id":"1b70dbdf-e900-404f-822a-3da530a6ef0c","vocabulary_id":"2","name":"Atlantic Salmon"},{"id":"8327aa87-6ee8-4098-a484-1b7f2b38065e","vocabulary_id":"2","name":"fisheries management"},{"id":"7a474f49-ddaf-4f61-817b-04961f917c10","vocabulary_id":"2","name":"freshwater fisheries"},{"id":"6510a256-38eb-4bd3-b1d9-b8318f80e8c0","vocabulary_id":"2","name":"stocking"}],"groups":[{"description":"\u003Cp\u003EFormal report series, containing results of research and monitoring carried out by Marine Directorate.\u003C\/p\u003E\n","id":"d0fc86dc-1394-43d4-aef1-c8cf5ac500f9","image_display_url":"https:\/\/data.marine.gov.scot\/sites\/default\/files\/\/reports_1.png","title":"Scottish Marine and Freshwater Science Reports","name":"group\/scottish-marine-and-freshwater-science-reports"},{"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"}]}]}
