However, individual fishers or fleets use up their quota for each stock at different rates. Under a landing obligation this leads to their fishing activity being \u201cchoked\u201d by the stock with the most limiting quota.\u003Cbr \/\u003E\nThis report explores the potential of four proposed multispecies-based management approaches to address this issue. This was done through simulating each management approach in a multi-stock, fleet-based model which included multiple demersal fish stocks and Norway lobster Functional Units from the North Sea.\u003Cbr \/\u003E\nThe results show that while all the management approaches went some way to lessen choking effects, only three of the approaches also kept stock sizes at healthy levels. Moreover, some fleets benefited more than others in terms of economic sustainability. The findings presented in this report identify which of the management approaches show the greatest potential for addressing the choke effect and would therefore be suitable candidates for further refinement and evaluation.\u003C\/p\u003E\n","url":"https:\/\/data.marine.gov.scot\/dataset\/evaluation-multispecies-management-approaches","state":"Active","private":true,"revision_timestamp":"Tue, 12\/16\/2025 - 09:01","metadata_created":"Fri, 12\/05\/2025 - 09:41","metadata_modified":"Tue, 12\/16\/2025 - 09:01","creator_user_id":"ef1d5231-9817-4ea3-875e-aadc55addee0","type":"Dataset","resources":[{"id":"e2e16af1-a513-4239-b1c9-4217537fb2c7","revision_id":"","url":"https:\/\/www.gov.scot\/publications\/evaluation-multispecies-management-approaches\/","description":"\u003Cp\u003EAccess the report on the Scottish Government publications\u003C\/p\u003E\n","format":"html","state":"Active","revision_timestamp":"Tue, 12\/16\/2025 - 09:01","name":"Report: An evaluation of multispecies management approaches","mimetype":"html","size":"","created":"Tue, 12\/16\/2025 - 09:01","resource_group_id":"101d17a8-ed4c-47dc-baec-0d48b9c425e5","last_modified":"Date changed  Tue, 12\/16\/2025 - 09:01"}],"tags":[{"id":"72fc9729-c09b-4370-aae4-aa7769b019a1","vocabulary_id":"2","name":"fish biomass in water bodies"},{"id":"87ad971e-1536-43bb-b5ae-c7a5d7e7d84f","vocabulary_id":"2","name":"fishery characterisation"},{"id":"c0c074e2-ff1c-4a12-bcf3-d30245c7b6f6","vocabulary_id":"2","name":"fishing effort"},{"id":"8045c8ed-8547-452b-bc6d-8142bc42c624","vocabulary_id":"2","name":"fisheries"}],"groups":[{"description":"\u003Cp\u003EMarine Directorate manages quota for fish stocks and all inshore fisheries within the 12 nautical mile territorial water limit.
