Monthly fishing effort targetting tuna and tuna-like species in the East Pacific Ocean (1954-2015) by longliners aggregated by 5° squares (IATTC level 0)

This dataset lists fishing effort targetting tuna and tuna-like species from the Commission for the Inter-American Tropical Tuna Commission (IATTC) by longliners from 1954 to 2015. Efforts are stratified by year, month, fishing gear, vessel flag reporting country, unit of effort, area (5° squares). It corresponds to the effort part of the IATTC catch-and-effort (task2) dataset.

Efforts are expressed in number of hooks.

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.
