Book (series)Technical bookElasmobranchs 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. -
No Thumbnail AvailableBook (series)Technical studyStatus of Interactions of Pacific Tuna Fisheries in 1995
Proceeding of the Second FAO Expert Consultation on Interactions of Pacific Tuna Fisheries Shimizu, Japan 23 to 31 January 1995
1996Also available in:
No results found.This publication includes forty papers and two abstracts of papers presented at the Second FAO Expert Consultation on Pacific Tuna Fisheries held in Shimizu, Japan, from 23 to 31 January 1995. The topics of the papers include: · reviews of tuna fisheries interactions and their research including methods for their study, · new methods for studying tuna fisheries interactions and examination of their applicability, · case studies on tuna fisheries interactions, · analyses of tuna fisheri es involved in interactions and their management, and · an overview of FAO’s project that co-organized and co-sponsored the Consultation. A supplement of an indexed bibliography of papers on tuna and billfish tagging, which was printed separately, is also included. The objectives of the Consultation were to: · review and integrate the outcome of the studies on tuna fisheries interactions, · summarize the extent of tuna fisheries interactions and unresolved research problems, and · fo rmulate guidelines for research on tuna fisheries interactions. The understanding of tuna fisheries interactions was enhanced significantly by recent studies. However, the Consultation noted that the number of quantified interactions is still small due primarily to difficulties associated with evaluating such interactions. The papers providing supporting information for the conclusions of the Consultation are presented in this publication. Interactions were found to vary in significance depend ing on the biological characteristics of the species involved, the sizes of fish caught, the local and stock-wide rates of exploitation, and the distance among fisheries. In many of the studies presented, the inadequacy of fisheries data was stressed. In addition, the lack of understanding of movements of the fish being studied was noted in several papers. General qualitative guidelines presented in several discussion papers stressed that specifically-designed studies be undertaken to adequately quantify interactions. Well-designed tagging experiments were thought to provide the most reliable information about interactions. Guidelines for the collection of data, biological and ecosystem research, modelling, and alternative methodologies for studying tuna fisheries interactions are also included. -
Book (series)Technical reportA review of the inland fisheries of India 2024
Also available in:
No results found.India has abundant water resources including rivers, canals, ponds, lakes, reservoirs, upland lakes, and floodplain wetlands covering over 5.8 percent of the country. These environments harbour a rich fish fauna of 1 035 species that constitutes the basis for the inland fisheries sector, which annually produces 2 144 452 tonnes of fish – if enhanced and culture-based fisheries are included – corresponding to 21 percent of total fish production. Rivers like the Ganga, Brahmaputra, and Barak, alongside floodplain wetlands, play crucial roles, especially in the east and northeast. Lakes are abundant in upland areas. Reservoirs cover over 1 percent of India's land and hold untapped potential for fisheries development. Traditionally, fishing in inland water bodies has been a small-scale or subsistence activity. Fishing practices, crafts and gear used in inland fisheries are still traditional. Cooperative societies are present in reservoirs and wetlands giving fishers better bargaining power with traders and better prices for the fish. Inland fisheries are imperative for poverty alleviation, food security, gender empowerment, cultural services, ecosystem function, and biodiversity, and are important for achieving the Sustainable Development Goals. Important threats to inland fisheries include water scarcity, habitat loss, pollution, climate change and invasive species. However, several major river conservation programmes have been initiated.The collection of inland fishery catch statistics remains weak and production appears to be significantly under-reported in many states. A simplified method for defining water bodies and estimating catch is proposed and all States have been advised to follow the same definition for water bodies.

Book (series)FlagshipThe 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. -
