ICCAT Manual

For several years, SCRS scientists have recognized the need to update the ICCAT Field Manual (the last version was published in 1990). In addition, it has been noted that a revision should be broader in scope than the current version. The Commission has also noted the need for a publication that compiles all of the data submission forms in order to facilitate the reporting requirements of Contracting Parties.

The publication will be of use to a wide audience, maintaining scientists as the primary intended users. Various chapters of a general nature should allow readers to understand how ICCAT works and what is the role of statistics and research within the system. Other chapters would contain technical guidelines for species identification or for sampling, and appendices that specify the formats with which data should be submitted to the Secretariat. The ICCAT Manual is under development. The table below provides links to sections that have already been developed.
