ICCAT·CICTA·CICAA

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.

Nominal Catch Information

Nominal annual catch by species, region, gear, flag, and where possible, separated between EEZ and High Seas. In general, responsibility for reporting catch and landings data rests on flag states.

Task I web

Web-based application to view nominal catches of Atlantic tunas and tuna-like fish (including sharks), by gear, region and flag in web application [version 11/2018].

Task I Excel

MS Excel pivot table to obtain nominal catches of Atlantic tunas and tuna-like fish (including sharks), by gear, region and flag [MS Excel; version 11/2018, 7 Mb(7z)]

*Task I Fishstat

Time series of nominal catches for Atlantic tunas and tuna-like fish (excluding sharks) for use with FAO's FISHSTAT. (Requires download and instalation of FISHSTAT).

Sample fishing statistics and fish sizes

Catch and fishing effort statistics for each species by small area (1x1 degree squares for most gears, 5x5 degree squares for longlines), gear, flag, and month. Task II data also include actual size frequencies of samples measured for each species by small area, gear, flag and month.
In some cases, detailed size samples are also extrapolated to match total catches in order to be used in stock assessments. This includes the CATDIS and catch-at-size datasets.

Other information

In addition to Task I and Task II data, the SCRS also makes use of other types of information for its analyses of the stocks, depending on need, relevance, and availability.

Observer data

Observer data currently available only for US longline, 1992-2000. [2,635 kb].

Statistical Bulletin

The Bulletin, updated annually, summarizes available information in a user-friendly format that includes multiple tables and graphs.
