This dataset lists the global catch (in metric tons,t) of tuna and tuna-like species from 1918-01-01 to 2019-12-31. This dataset was computed using public domain,annual nominal catch datasets (also called total catch) released by the five tuna Regional Fisheries Management Organizations (t-RFMOs):the Commission for the Conservation of Southern Bluefin Tuna (CCSBT),the Inter-American Tropical Tuna Commission (IATTC),the International Commission for the Conservation of Atlantic Tunas (ICCAT),the Indian Ocean Tuna Commission (IOTC) and the Western and Central Pacific Fisheries Commission (WCPFC). Species-specific catches are stratified by year,fishing gear,reporting / fishing fleet and area (essentially,the t-RFMOs competence areas apart from the CCSBT that has no defined area of competence and manages the global catch of southern bluefin tuna). "FIRMS level 0" identifies the processes applied to the primary datasets by the FIsheries and Resources Monitoring System (FIRMS) to generate the dataset. t-RFMO ...
