Other Effective area-based Conservation Measures (OECMs), together with MPAs, are an important element under the current Target 2 of the Post-2020 Global Biodiversity Framework. CBD Decision 14/8 calls for OECMs mainstreaming into sectors, including fisheries. Guidance is provided in the Decision and supplementary guidance has been developed by IUCN-WCPA. Specific guidance for the use of OECMs in the fishery sector has been developed by the IUCN-CEM Fisheries Expert Group (FEG) (Rice et al., 2018; Garcia et al, 2019; Garcia et al, 2020). The available guidance for OECMs identification in that sector has been recently tested in the North Atlantic, in an ICES-FEG working group (15-24/03/2021). This event will briefly present the results obtained through 5 case studies as a basis for a discussion around selected key implementation issues. The discussion will start with reactions from selected panellists and will be followed by a Q&A session with the audience.
