Book (series)Trends in oceanic captures and clustering of large marine ecosystems
Two studies based on the FAO capture database
2003Also available in:
No results found.Species items reported in the FAO capture fisheries production database have been classified as oceanic or living on the continental shelf. Catch trends of oceanic species, further subdivided into epipelagic and deep-water species, have been analysed over a 50-year period (1950-99) while statistics for shelf species have been re-assigned to large marine ecosystems (LMEs) for a shorter period (1990-99) and used to investigate catch patterns among the various LMEs. Oceanic fisheries constitut e, both in terms of number of species items and in quantities of recent catches, about 10% of global marine catches. Catches of epipelagic species (mostly tunas) and of deep-water species (mostly Gadiformes) have been continuously increasing and reached 8.6 million tons in 1999. Oceanic catches by distant water fleets (DWFs), mostly targeting tunas, have been decreasing in recent years although their share of total DWF catches has increased due to the concurrent drop of non-oceanic DWF catches. Trends of oceanic catches and the contribution of DWFs are examined for all FAO marine fishing areas which show different patterns, mainly depending upon whether they are temperate or tropical areas. Eleven clusters of LMEs have been identified on the basis of similarities in their catch composition classified into eleven species groupings. For each cluster, the distinguishing catch pattern and recent trends by species groupings in each LME are discussed, and considered in relation to infor mation on primary productivity and the abiotic characteristics of the LME. -
No Thumbnail AvailableBook (stand-alone)Workshop on Integrated Reef Resources Management in the Maldives - Bay of Bengal Programme 1997
Also available in:
No results found.For much of the world's tropical population, coral reefs are synonymous with reef fish and edible marine invertebrates. Reef-related fisheries are important to small-scale fisherfolk, as a source of both protein and livelihood security for local coastal communities. In all of Asia, coral reef resources play a role in the food and livelihood security of coastal communities. Perhaps nowhere in Asia in this role more important than in the Maldives. As a student working group in the Workshop put it, "The whole livelihood of the Maldivians depends on the reef resources." The Republic of Maldives initiated IRRM to improve the management of its reef resources. IRRM is supported by BOBP and combines scientific and fisherfolk knowledge with the expertise and input of all Ministries with jurisdiction in areas impacting reef resources. Issue areas for management under IRRM include (1) Reef fishery (2) Bait fishery for the tuna pole and line fishery (3) Coral mining (4) Tourism and fishery i nteractions and (5) Legal and institutional aspects of IRRM. The IRRM Workshop was convened to share scientific and socio-economic information on the five issue areas and to obtain a common understanding and agreement among the many government agencies, public interest groups and the private sector on the objectives and vision of the IRRN Programme. Participants examined the five issue areas and arrived at a consensus on recommendations to address each issue area. The Report and Proceedings c ontain the recommendations and the papers presented at the Workshop. -
No Thumbnail AvailableBook (series)Status 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.
