    The CWP, supported by the participating organizations, has served as the premier international and interorganizational forum for agreeing common definitions, classifications and standards for the collection of fishery statistics since 1960. It has developed common procedures for statistics collation which have streamlined processes and reduced the burden on the statistical offices of national fisheries, as well as providing technical advice to participating organizations on fishery-related statistical matters, and facilitating the publication of methodological and reference documents.


  • FAO will organize the "Technical workshop on global harmonization of Tuna fisheries statistics" from 19 to 22 March 2018 in FAO HQ, Rome.
    The meeting will be held under the frame of the CWP ad-hoc Task Group on reference harmonization, as tuna sub-group a focus on tuna RFMOs. The workshop will bring together representatives from the five Tuna RFMOs namely: CCSBT, IATTC, ICCAT, IOTC and WCPFC.
    The overall aim of the present ad-hoc Task Group is to elaborate a CWP standard for Data Structure Definition (DSD), a set and structure of statistical concepts that accommodate the coding system used by CWP parties to improve the data reporting and exchange between national, regional and global organizations.
    This technical workshop is a pilot case of harmonization of DSDs, classifications and related codification. Outputs will be presented to other CWP parties towards consensus on global DSDs for global capture, catch and effort, and logbooks.
  • CWP - Report of the Fifth Meeting of the Aquaculture Subject Group and the Twenty-sixth Meeting of the Fisheries Subject now available. Full report here
  • The First revision of the International Standard Statistical Classification for Fishing Gears (ISSCFG, Rev.1) has been endorsed for full operationalization by the CWP members. The revised classification and the correspondence between the two versions (ISSCFG 1980, Annex M I) and its revised version (ISSCFG Rev1, 2010) is also available.
  • CCAMLR has revised the boundary between Subareas 58.6 and 58.7 (Indian Ocean). The revised boundaries were agreed in October 2016 and have been applied retrospectively to the entire time series of the STATLANT data and trade statistics published in the CCAMLR Statistical Bulletin and FAO capture data sets. The revised map and metadata are available at http://www.fao.org/fishery/area/Area58/en.
