Book (stand-alone)Sharks, rays and chimaeras in Mediterranean and Black Seas
Key to identification
2022Also available in:
No results found.This guide contains the illustrated key to orders, families, genera and species to the Chondrichthyes of the Mediterranean and Black Seas (FAO fishing area 37), currently represented by 38 sharks, 48 batoids and 2 chimaeras. The species are described following the taxonomic order and are grouped in functional groups. Near the illustration of each species, the relevant diagnostic features are complemented by a set of icons representing the management measures and the data collection requirements as per existing GFCM recommendations. The technical terms and the minimum standard measurements are provided as annexes. -
Book (series)The State of Mediterranean and Black Sea Fisheries 2022 2022
Also available in:
No results found.The 2022 edition of the flagship publication of the GFCM, The State of Mediterranean and Black Sea Fisheries, provides an up-to-date overview of fisheries status, trends and governance in the region. Now in its fourth instalment, the publication updates the findings from previous editions while analysing emerging issues in the fisheries sector, including the effects of management plans. For the first time, thanks to the recent consolidation of data quality indicators, trends in the fisheries sector are also analysed at the regional level. Based on data and information from GFCM contracting parties and cooperating non-contracting parties, The State of Mediterranean and Black Sea Fisheries 2022 delivers the most comprehensive picture of fisheries in the region to date. Against the backdrop of the impacts of the COVID-19 pandemic and of renewed strategic commitments, the first two chapters present the characteristics of the Mediterranean and Black Sea fisheries sector, with figures on the fleet and capture fisheries production; chapters three and six showcase the human dimension behind fisheries through socioeconomic data and specific insights on small-scale fisheries, given their relative importance; chapters four and five provide an overview of the status of commercial living resources and of vulnerable species; and chapter seven outlines the measures taken and remaining challenges towards building a sustainable future for fisheries at the subregional and regional levels. The objective of The State of Mediterranean and Black Sea Fisheries is to deliver useful, reliable data to a wide audience as an essential source of information on the fisheries sector in the region and a key tool to support decision-making and monitor progress towards the goals set by the GFCM. -
Book (series)Elasmobranchs of the mediterranean and black sea: status, ecology and biology, biographic analysis 2012
Also available in:
No results found.The authors have compiled published information on taxonomy, distribution, status, statistics, fisheries, bycatch, biologic and ecologic parameters on age and growth, food and feeding habits, reproductive biology and stock assessment of elasmobranchs in the Mediterranean and Black Sea. This bibliographic analysis, through 661 papers dealing with elasmobranchs in the GFCM area, shows that cartilaginous species, including sharks, rays and chimaeras, are by far the most endangered group of marine fish in the Mediterranean Sea, with 31 species (40 percent of all) critically endangered, endangered or vulnerable. The biological characteristics of elasmobranchs (low fecundity, late maturity, slow growth) make them more vulnerable to fishing pressure than most teleost fish. Overfishing, wide use of non-selective fishing practices and habitat degradation are leading to dramatic declines of these species in the Mediterranean Sea. In general, elasmobranchs are not targeted but are caught incidentally. In many fisheries they are, however, often landed and marketed. The study also highlights the following points: – Works are concentrated mainly in the western Mediterranean. Few works concern endangered species and those of the GFCM priority list; – Much systematic confusion persists for some species and some others are doubtful; – The IUCN red list shows clearly the vulnerability of elasmobranchs and the lack of data; – A decline in cartilaginous fish speci es landings has been observed while fishing effort has generally increased; – A standardization of methods and expression of results on the biology should be generalized in the whole Mediterranean; – Papers on biologic parameters concern few species primarily in the occidental and central Mediterranean areas. Therefore, recommendations to fill gaps in order to protect and manage elasmobranchs stocks are proposed in this document. In fact, better understanding of the composition of incidental and targeted catches of sharks by commercial fisheries and biological and ecological parameters are fundamentally important for the conservation of these populations. Moreover, problems encountered by elasmobranchs in the GFCM area are highlighted and conservation measures are suggested.
