Monthly fishing effort targetting billfishes in the East Pacific Ocean (1993-2015) by purse seiners aggregated by 1° squares and by flag (IATTC level 0)

This dataset lists fishing effort targetting billfish species from the Commission for the Inter-American Tropical Tuna Commission (IATTC) by purse seiners from 1993 to 2015. Efforts are stratified by year, month, fishing gear, vessel flag reporting country, unit of effort, area (1° squares). It corresponds to the effort part of the IATTC catch-and-effort (task2) dataset.

Efforts are expressed in number of sets.

This dataset was downloaded on the IATTC website. It was then restructured to be in line with the Sardara database structure (columns normalization, names, etc.). However the content of data and the code lists were kept exactly as their are available in the source dataset.

The description below (caracteristics, specific issues and problems that need to be taken into account) is extracted from the IATTC web page where the dataset has been downloaded.

Caracteristics, specific issues and problems that need to be taken into account :

Stratification by fishing mode (i.e. type of school used) is not available in this dataset, since IATTC confidentiality policy restricts the release of public domain data by both flag and set type.

The file contain data provided by Members and Cooperating Non-Members Estimated East Pacific Ocean billfish bycatch totals are presented in the Inter-American Tropical Tuna Commission (IATTC) Fishery Status Reports (http://www.iattc.org/FisheryStatusReportsENG.htm). In accordance with the IATTC policy on confidentiality, data from flags with less than 3 vessels or less than 3 companies are grouped in the “Other” category in the “Flag” column.
