The ICCAT Secretariat maintains over 2 gigabytes of information in various databases. Most of these can be accessed through the links below. We are currently working on making available the remaining datasets via Internet.

The dissemination of ICCAT data is according to the Rules and Procedures for the protection, access to, and dissemination of data compiled by ICCAT, adopted by the Commission in 2010. While most databases currently used in the stock assessments and other SCRS work are of public domain and are published in this web page, the aforementioned rules also include procedures for using data classified as confidential. Such confidential data are voluntarily provided by CPCs for specific use by the SCRS.
