    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

    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.

    Deep-sea fisheries in the high seas - Ensuring sustainable use of marine resources and the protection of vulnerable marine ecosystems. 2009
    Also available in:

    Deep-sea fisheries are fisheries that take place at great depths (up to 1 600 metres). Deep-sea fisheries that occur in waters beyond national jurisdiction (such as the exclusive economic zone ¿ EEZ), take place in the high seas. The great depths and distances from the coast at which marine living resources are caught by deep-sea fisheries in the high seas pose scientific and technical challenges in providing scientific support for management. A great deal of work has been accomplished in the last few years, in terms of achieving responsible management of these fisheries, but much remains to be done in creating more appropriate institutions. RFMOs/As will need to be established where they do not exist or duly mandated to address deep-sea high seas fisheries. States and RFMO/As will also need to pursue efforts initiated in implementing international guidance and developing the appropriate set of policies and measures required for the effective management of fisheries and conservat ion of marine biodiversity. The FAO International Guidelines provide a good framework and starting point to develop that kind of approach. FAO is building up a special programme to support the effective implementation of the guidelines through, inter alia, institutional building, policy development, improvement of methodologies and management for the identification of VMEs and the development of appropriate fisheries management approaches.

    Improving Sustainability of Deep-Sea Fisheries and Ecosystems - GCP/GLO/366/GFF 2021
    Also available in:

    Deep Sea Fisheries (DSF) occur at great depths in the Areas Beyond National Jurisdiction (ABNJ) and constitute a small fraction of global fisheries; however, DSF are often highly valuable, generating up to USD 620 million annually. Interest in deep sea species has led to concerns about their enhanced vulnerability as a result of increased fishing activities and the potential damage caused by bottom contact fishing gears to fragile benthic ecosystems like coral reefs and sponge grounds. Although significant progress has been made in promoting sustainable DSF and protecting biodiversity in the ABNJ, the pace and scope of management measures and scientific understanding needs to be expanded, given the known vulnerability of deep sea fish stocks, associated bycatch species and habitats. Greater international and consumer pressure, as well as raised awareness and readiness for action among stakeholders, are now creating favourable conditions for acting decisively in support of the implementation of relevant policy and legal frameworks that are strengthening spatial planning and control measures, including the improved protection of sensitive areas such as vulnerable marine ecosystems (VMEs). The main objective of this project one of four projects making up the Global Environment Facility financed Program on Global Sustainable Fisheries Management and Biodiversity Conservation in ABNJ was to achieve efficiency and sustainability in the use of deep sea living resources and improving biodiversity conservation in the ABNJ. It aimed to achieve this through the systematic application of an ecosystem approach to: ( i ) improving sustainable management practices for DSF, taking into account the impacts on related ecosystems, (ii) improving the protection of VMEs and enhanced conservation and management of components of ecologically and biologically significant areas and (iii) testing area based planning tools for deep sea ecosystems.
