This dataset lists the global catch of tuna and tuna-like species from 1918-01-01 to 2019-12-31. Species-specific catches are stratified by year,fishing gear,vessel flag reporting country and area ,essentially the tuna RFMOs areas of management. This dataset was computed using public domain catch datasets released by the five tuna Regional Fisheries Management Organizations:the Indian Ocean Tuna Commission (IOTC),the International Commission for the Conservation of Atlantic Tunas (ICCAT),the Inter-American Tropical Tuna Commission (IATTC),The Western and Central Pacific Fisheries Commission (WCPFC),the Commission for the Conservation of Southern Bluefin Tuna (CCSBT). IRD Level 0 stands for the processes applied to the primary datasets by the French National Research Institute for Sustainable Development (IRD) to generate the dataset.(database version) This dataset lists global catch of tuna and tuna-like species from 1918 to 2015. Catches are stratified by year,species,fishing gear,vessel flag reporting country,area (essentially the tuna RFMOs areas of management). This dataset was computed using public domain catch-and-effort datasets released by the five tuna Regional Fisheries Management Organizations:the Indian Ocean Tuna Commission (IOTC),the International Commission for the Conservation of Atlantic Tunas (ICCAT),the Inter-American Tropical Tuna Commission (IATTC),The Western and Central Pacific Fisheries Commission (WCPFC),the Commission for the Conservation of Southern Bluefin Tuna (CCSBT). IRD Level 0 stands for the processes applied to the primary datasets by the French National Research Institute for Sustainable Development (IRD) to generate the dataset. These processes for level 0 at global scale are :- Merging of the primary nominal (also called total) catch datasets released by the 5 tuna RFMOs.- For the Southern Bluefin Tuna,only data from the the Commission for the Conservation of Southern Bluefin Tuna (CCSBT) was kept (i.e. data from the other RFMOs for SBF was removed).- Original code lists have been mapped with standard FAO code lists (for gears,species,flags). These mappings have been done in collaboration with the RFMOs secretariats.More details on the processes are provided in the lineage section.
