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. -
Book (series)Depleted marine resources: an approach to quantification based on the FAO capture database. 2004
Also available in:
No results found.The 2002 United Nations World Summit on Sustainable Development called for species whose catches had been drastically depleted to be restored to health within 2015. An approach is proposed here to a preliminary classification, based solely on information included in the FAO capture database. Three criteria were used to filter catch data: the trend in recent years, the long-term trend, and the extent of decline in catches over the long term. These were applied sequentially to the data series for species items by fishing area recorded in the FAO capture database. About ten percent of the species items examined matched the selecting criteria. This is the same proportion of stocks classified as “depleted” by FAO based on assessment data although there are differences in the species identified. Reasons for these discrepancies are discussed. The species groups with the highest percentages of species matching the three criteria were Gadiformes, molluscs (excluding cephalopods) and miscellan eous coastal and demersal fishes. Pelagic fishes (including Clupeoids) and crustaceans showed low percentages of depleted resources. Species considered depleted by this procedure are listed by FAO fishing area. -
Book (series)Report of the Fourth Intergovernmental Consultation on the Establishment of a Southwest Indian Ocean Fisheries Commission, Mahe, Seychelles, 13-16 July 2004/ Rapport de la quatrième Consultation intergouvernementale sur la création d’une Commission des pêches pour le sud-ouest de l’océan Indien, Mahé, Seychelles, 13-16 juillet 2004 2005

No results found.This document is the final report of the Fourth Intergovernmental Consultation on the Establishment of a Southwest Indian Ocean Fisheries Commission, held in Mahe, Seychelles, from 13 to 16 June 2004. The Consultation was attended by delegates from ten States, the European Community, and two observer organizations. The Consultation unanimously adopted a draft Resolution and Statutes for the establishment of the South West Indian Ocean Fisheries Commission for submission to the FAO Council. The Consultation also carried out a first reading and discussion of a draft text of an instrument for the high seas. As an interim measure, until the establishment of a high seas instrument, a Resolution concerning the collection and handling of information and data was adopted.
