    The Scientific Advisory Committee on Fisheries (SAC) of the General Fisheries Commission for the Mediterranean (GFCM) held its twenty-second session online, from 22 to 25 June 2021. The session was attended by delegates from 19 Mediterranean contracting parties, 11 observers, as well as representatives of the Food and Agriculture Organization of the United Nations (FAO) Fisheries Division, the GFCM Secretariat and invited experts. The Committee reviewed the work carried out during the 2019–2021 intersession, including within the framework of the mid-term strategy (2017–2020) towards the sustainability of Mediterranean and Black Sea fisheries and in light of the COVID-19 pandemic, and provided advice on status of priority stocks and ecosystems and on potential management measures addressing key fisheries and vulnerable species in the Mediterranean. In line with the subregional approach, the Committee formulated advice focusing on: i) small pelagic and priority demersal fisheries in the Adriatic Sea; ii) common dolphinfish and blackspot seabream fisheries in the western Mediterranean; iii) small pelagic and bottom trawl fisheries exploiting demersal stocks, particularly European hake, in the central Mediterranean; iv) deep-water red shrimp fisheries in the eastern-central Mediterranean, including their interactions with vulnerable marine ecosystems; and v) round sardinella in the eastern Mediterranean. The Committee also agreed on the technical soundness of three FRA proposals for the Bari Canyon, the Ebro Delta margin and the Palmahim Disturbance, to be submitted to the Commission. At the regional level, the Committee provided advice on the following: i) fishing technology and bycatch, including minimal technical specifications for bottom-trawl nets and the need for targeted pilot projects to investigate possible mitigation measures; ii) data call for the database on sensitive benthic habitats and species and other effective area-based conservation measures for the protection of vulnerable marine ecosystems and essential fish habitats; and iii) advances in the adaptation strategy for climate change. Furthermore, the Committee discussed additional work in support of the GFCM, namely the implementation of the Regional Plan of Action for Small-Scale Fisheries in the Mediterranean and the Black Sea, dedicated research programmes as well as other activities to enhance fisheries management in the region. Finally, the Committee agreed upon its work plan for 2021–2023.

    This report presents the outcomes of the twenty-fourth session of the GFCM Scientific Advisory Committee on Fisheries. The Committee reviewed the work carried out during the 2022–2023 intersession, including in the context of the MedSea4Fish programme, and provided advice on the status of priority stocks and ecosystems and on potential management measures addressing key fisheries and vulnerable species in the Mediterranean. At the regional level, the Committee provided advice on: i) European eel, red coral and common dolphinfish fisheries in the Mediterranean; ii) minimum conservation reference size for GFCM priority species, including deep-water red shrimp and European hake at the regional level as well as small pelagics in the Adriatic sea and round sardinella in the eastern Mediterranean; and iii) the socioeconomic impacts of a potential extension of bottom trawling limits. With regard to small-scale fisheries, the Committee supported the need to revise the monitoring framework of the Regional Plan of Action for small-scale fisheries in the Mediterranean and the Black Sea. It discussed additional work in support of the GFCM, endorsing dedicated research programmes, including on recreational fisheries and on jellyfish in the Alboran Sea, as well as a draft regional plan of action to monitor and mitigate interactions between fisheries and vulnerable species in the Mediterranean and the Black Sea and identified further actions towards the implementation of standardized monitoring plans for fisheries restricted areas (FRAs) and the development of pilot studies to identify boundaries of known vulnerable marine ecosystems. It also discussed issues related to decarbonization and climate change, estimation of discards and fishing capacity. In line with the subregional approach, the Committee formulated advice on i) blackspot seabream in the western Mediterranean; ii) small pelagics in the Alboran Sea; iii) a FRA in the Cabliers Coral Mound Province; iv) Norway lobster, red mullet and striped red mullet in the central Mediterranean; v) round sardinella, small-scale fisheries and non-indigenous species in the eastern Mediterranean; and vi) small pelagics and key demersal stocks in the Adriatic Sea. Finally, the Committee agreed upon its workplan for 2023–2025.

    General Fisheries Commission for the Mediterranean – Report of the twenty-third session of the Scientific Advisory Committee on Fisheries, FAO headquarters, Rome, Italy, 21–24 June 2022 2022
    Also available in:

    The Scientific Advisory Committee on Fisheries (SAC) of the General Fisheries Commission for the Mediterranean (GFCM) held its twenty-third session in hybrid modality, from 21 to 24 June 2022. The Committee reviewed the work carried out during the 2021–2022 intersession and endorsed the MedSea4Fish guiding document, which provides an implementation framework following the establishment of the programme at the forty-fourth session of the GFCM (online, November 2021). The Committee provided advice on the status of priority stocks and ecosystems and on potential management measures addressing key fisheries and vulnerable species in the Mediterranean, including for European eel and red coral. In line with the subregional approach, the Committee formulated advice focusing on: i) common dolphinfish (Coryphaena hippurus) and blackspot seabream (Pagellus bogaraveo) fisheries in the western Mediterranean; ii) small pelagic and bottom trawl fisheries exploiting demersal stocks, particularly European hake (Merluccius merluccius) and deep-water rose shrimp (Parapenaeus longirostris), in the central Mediterranean; iii) deep-water red shrimp, giant red shrimp and blue and red shrimp (Aristaeomorpha foliacea and Aristeus antennatus) fisheries in the eastern-central Mediterranean, including their interactions with vulnerable megafauna; iv) non-indigenous species in the eastern Mediterranean, and v) small pelagic and demersal fisheries in the Adriatic. The Committee also agreed on the technical soundness of a proposal for the establishment of a fisheries restricted area (FRA) in the Cabliers Coral Mound, reviewed and endorsed a proposal for a large scale multiannual pilot study on trawl selectivity in the Strait of Sicily and reviewed the updated proposal from Libya to divide the Libyan coast (geographical subarea 21) into three marine subareas, to be submitted to the Commission. At the regional level, the Committee provided advice on the following: i) minimum conservation reference size for GFCM priority species; ii) spatial distribution of fishing effort, especially bottom trawl fisheries, to understand the spatial dynamics of specific fisheries and inform spatial management measures, including vulnerable marine ecosystems and other effective area-based conservation measures; and iii) ensuring and assessing the effectiveness of FRAs and establishing minimal standards for the monitoring of FRAs. With regard to recreational and small-scale fisheries, the Committee endorsed lists of species of importance and expressed support for a dedicated research programme for recreational fisheries.
