Book Description
Bycatch – a term widely used to refer to the part of catch unintentionally captured during a fishing operation, in addition to target species, and consisting of discards and incidental catches of vulnerable species – is considered one of the most important threats to the profitability and sustainability of fisheries, as well as to the conservation of the marine environment and ecosystems. In the Mediterranean, studies on the incidental catch of vulnerable species cover only a small portion of the total fishing activity. In addition, there are several important knowledge gaps for many types of fishing gear, and several countries and/or subregions, as well as on temporal scales, and only a few measures are in place that address the protection of vulnerable species. Monitoring programmes and surveys on incidental catches, which follow a harmonized methodology allowing for results to be compared across subregions, are necessary to improve knowledge on the issue and to subsequently support the identification of potential mitigation methods and tools, and relevant management measures. This publication and the methodology contained herein aim to provide a framework for the development and implementation of an efficient, standardized data collection and monitoring system for all vulnerable species encountered in the Mediterranean and the Black Sea, namely elasmobranchs, marine mammals, seabirds, sea turtles, and macrobenthic invertebrates.

Book Description
Discards – the part of the catch that is not retained on board, which may include target species or any other (commercial and non-commercial) species that are returned at sea dead or alive – usually result in a reduction of harvesting opportunities and may have negative consequences on the stocks, ecosystems and the marine environment. In the Mediterranean and the Black Sea, studies on discards only cover a small portion of the total fishing activities and discard rates are often poorly estimated or totally unknown. Information is lacking for many types of fishing gear, countries and GFCM subregions, and most available studies only cover relatively short periods and small areas. Discards therefore represent a major source of uncertainty about the actual fishing mortality rates of stocks. These knowledge gaps highlight the need to expand discard monitoring programmes and standardize practices, so to assess discards appropriately and address their important impacts. This publication and the methodology discussed herein aim to provide a framework for the development and implementation of an efficient, standardized data collection and monitoring system for discards through on-board observations, questionnaires at landing sites and self-sampling activities. It ensures minimum common standards for the collection of discards data and allows for repeatability and comparisons among fisheries across the region, thus offering a harmonized basis of knowledge, information and evidence for decision-making.

Book Description
Bycatch – a term widely used to refer to part of the catch unintentionally caught during a fishing operation, in addition to target species, and consisting of the discards and incidental catch of vulnerable species – is considered one of the most important threats to the profitability and sustainability of fisheries, as well as to the conservation of the marine environment and ecosystems. Understanding the bycatch issue and adopting effective measures in order to reduce bycatch rates are essential steps towards minimizing the impacts on vulnerable species and ensuring both a sustainable fisheries sector and healthy seas. In the Mediterranean and the Black Sea, the incidental catch of vulnerable species – namely seabirds, sea turtles, elasmobranchs, marine mammals and macrobenthic invertebrates – represents one of several challenges for the industrial, semi-industrial and small-scale fisheries that coexist in the region, as well as for the diverse and sensitive ecosystems impacted. Typically, data on this issue have been collected in an opportunistic manner and in ways that make comparisons difficult. The annual absolute values of incidental catch of vulnerable species are not available: studies cover only a small portion of the total fishing activity and often present important knowledge gaps for many types of fishing gear, countries and/or subregions, as well as on temporal scales, for example, to establish reliable baselines. The result is that little is known of the scope of the problem, despite incidental catch being a significant pressure on the populations of vulnerable species, as well as a concern for fishers.This regional review is an attempt to compile, in one single document, all available data and historical records on the incidental catch of vulnerable species in the Mediterranean and Black Sea fisheries, obtained from existing literature, databases and other grey sources, and collated in a standardized and comparable way. The main objective is to provide comprehensive baseline information, earmark the main data gaps, as well as identify the most impacting types of fishing gear by taxonomic group. This work is a reminder of the importance of standardized data collection and the need to have baseline information in order to support decision-making in the identification of appropriate bycatch mitigation techniques, thus enabling analysis of their effectiveness and comparison over time and space, as well as facilitating the implementation of relevant conservation and/or management measures at the national, subregional and regional levels.

Book Description
This third edition of the State of Mediterranean and Black Sea Fisheries provides a comprehensive overview of the status of fisheries in the region, looking at their main features and trends, in order to better inform their management and better examine current and future challenges that they will face in the near future. The aim of this report is to produce a document that could provide useful analysis and direction for decision-making and future action. In this respect, this publication also represents a convenient source of information for the FAO Committee on Fisheries and offers a practical complement to the data provided in the State of World Fisheries and Aquaculture published by the FAO Fisheries and Aquaculture Department. This volume includes seven chapters divided into two sections: a first part on the status and trends of different aspects of Mediterranean and Black Sea fisheries, including fleet, catches, socio-economic variables and bycatch, and a second part that focuses on the management of Mediterranean and Black Sea fisheries, including an overview on small-scale fisheries. This report is based to a large extent on the most up-to-date data available submitted by GFCM contracting and cooperating non-contracting parties, including information on stock status, national catches, fleet and socio-economic information up to 2018. It is also complemented with information from other sources.

Book Description
Marine mammal depredation refers to the phenomenon of marine mammals partially or completely removing catch from fishing gear. Its results, which can affect the survival of wild dolphin populations, as well as damage gear or target fish, disturb fishing activities and generate economic losses for fishers, are a growing cause for concern in several Mediterranean and Black Sea fisheries. Depredation events often leave dolphins injured or snared in fishing nets and fishers with damaged nets and lower catch values. As a result, these interactions can create conflicts between dolphins and fishers, undermining efforts to improve the sustainability of fisheries and the conservation of vulnerable species. This review offers an overview of historical and current trends of depredation by marine mammals in the region, including information on the contiguous Atlantic area west of Gibraltar. The publication aims to assess and synthesize depredation records and describe ongoing projects on depredation in order to improve knowledge on key aspects of depredation, such as the fishing practices associated with depredation events, the economic fallout caused by marine mammal–fisheries interactions and the species and populations most involved in depredation. In the Mediterranean and the Black Sea, coastal fisheries often come into contact with cetaceans, especially bottlenose dolphins (Tursiops truncatus), common dolphins (Delphinus delphis) and harbour porpoises (Phocoena phocoena relicta). These species feature most prominently in the depredation records assessed and are the main research focuses of ongoing monitoring projects in the region. However, Mediterranean monk seals (Monachus monachus) are also responsible for depredation, especially in the eastern Mediterranean, and are the subject of their own short chapter in this review.

Book Description
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.

Book Description
In the Mediterranean and the Black Sea, the assessment of demersal stocks mainly relies on scientific surveys (bottom and beam trawl) while the assessment of pelagic stocks is essentially based on acoustic surveys using acoustic techniques with mid-water trawling. These routine surveys-at-sea provide essential information, which in turn are crucial to fine-tune the assessments of the status of resources and to estimate more precisely indicators at the population and fish community levels. However, survey practices differ from one subregion to another, each approach having its own strengths and limitations. In addition, there is still a lack of large-scale standardized surveys aimed at analysing the diversity and distribution of the main demersal and pelagic species across the Mediterranean and the Black Sea. One way of tackling this issue is to carry out international scientific surveys covering the main demersal and pelagic stocks based on a common methodology. The methodology presented in this publication aims at supporting the planning and implementation of regional demersal (bottom and beam) trawl and pelagic acoustic surveys. It can be useful for the implementation of new surveys-at-sea in areas where demersal trawl and pelagic acoustic surveys are not regularly carried out. It can also contribute to increasing comparability between existing surveys thanks to the standardization of methods, sampling of catches and data recording and analysis. Finally, it represents a valuable tool to define minimum requirements towards sustainability and management objectives at the regional and subregional level.

Book Description
The Scientific Advisory Committee on Fisheries (SAC) of the General Fisheries Commission for the Mediterranean (GFCM) held its twentieth session in Tangiers, Morocco, from 26 to 29 June 2018. The session was attended by delegates from 14 Mediterranean contracting parties, seven observers, representatives of the FAO regional projects, the GFCM Secretariat and invited experts. The Committee reviewed the work carried out during the 2017–2018 intersession, including within its four subregional subsidiary bodies (Subregional Committee for the Adriatic Sea, Subregional Committee for the Central Mediterranean, Subregional Committee for the Eastern Mediterranean and Subregional Committee for the Western Mediterranean) which all met during the intersession. In relation to the mid-term strategy (2017–2020) towards the sustainability of Mediterranean and Black Sea fisheries, the Committee welcomed the progress in multiple priority activities as well as cooperation with partners. Issues in relation to fishery data quality, data collection needs and methodologies, estimation and quantification of illegal, unreported and unregulated fishing and formulation of advice on the status of fisheries were discussed. Recalling the need to improve knowledge on small-scale fisheries in the the Mediterranean and the Black Sea, the work underway to test a characterization matrix as well as the forthcoming Regional Plan of Action for Small-Scale Fisheries in the Mediterranean and Black Sea were tackled. Furthermore, the Committee formulated advice on the following aspects: i) overall status of Mediterranean stocks; ii) management of European eel; iii) management of deep-sea fisheries and identification of VMEs and iv) roadmap towards a network of essential fish habitats. In line with the subregional approach and based on the conclusions of the four subregional committees, the SAC also provided specific advice for each subregion. In particular, attention was paid to: i) blackspot seabream in the western Mediterranean; ii) demersal fisheries in the Strait of Sicily; iii) small pelagic fisheries in the Adriatic Sea; iv) demersal fisheries in the Adriatic Sea, including the monitoring of the Jabuka/Pomo Pit fisheries restricted area; and v) deep-water red shrimps in the central and eastern Mediterranean. In addition, the Committee also endorsed un updated table of priority species by subregion. Finally, the Committee agreed upon its work plan for 2018–2020 and elected its new Bureau.

Book Description
The 2018 edition of The State of Mediterranean and Black Sea Fisheries (SoMFi 2018), the flagship publication of the GFCM, provides a comprehensive overview of regional and subregional trends in Mediterranean and Black Sea fisheries. Bringing together data and indicators submitted by GFCM contracting parties and cooperating non- contracting parties on stock status, national catches, fleet and socio-economic aspects as well as information obtained from other sources, SoMFi 2018 aims to provide objective, reliable and up-to-date information to a wide audience and support decision-making in fisheries. SoMFi 2018 is divided into eight chapters. The first analyses the current composition of the fishing fleet, including information on fleet capacity, vessel types and age classes. Next comes a detailed breakdown of overall capture fishery production with comparisons of the latest figures to data from previous years, highlighting significant changes and trends. The report then looks at what this means for regional economies and for the livelihoods of the people who depend on the fisheries sector. As small-scale fisheries make up a large majority of Mediterranean and Black Sea fisheries, they receive special focus. SoMFi 2018 also provides the most detailed assessment yet of the state of fishery resources in the region. It shows the current status of the stocks, including those most at risk from overfishing, and looks at related issues like discards and incidental catches of vulnerable species. The report then highlights GFCM’s strategic efforts to build long-term sustainability, as it works with its stakeholders to sustainably manage fisheries and improve coastal livelihoods across the region. Finally, SoMFi 2018 concludes with an overview of the important role fisheries have to play in achieving the United Nations Sustainable Development Goals, maintaining healthy ecosystems and productive fisheries.
