Annual captured skipjack tuna mass

This quantity comes from a time series measurement and the most recent value (2018) is reported.

Summary:		Skipjack are the smallest and most abundant of the major commercial tuna species. Catches of skipjack tuna have been steadily increasing since 1950, and as of 2018 they represent the third most exploited fish species after the Peruvian anchoveta and the Alaska pollock. As of 2011, skipjack tuna was not considered overfished (Juan-Jordá et al., PNAS, 2011).
Method:		Information on capture production is collected annually from relevant national offices concerned with fishery statistics, by means of a system of standardized forms, which list for each country the relative species items and fishing areas breakdown. In the case of some "aquatic products", data are also obtained from trade associations or other specialized international organizations to which data are also submitted. In this way the statistics are reviewed by subject matter specialists. Data concerning the nominal catch of certain major groups are generally reviewed in collaboration with the regional agency concerned. For example, for ISSCAAP group 36 (Tunas, bonitos and billfishes) data provided by the national correspondents are often replaced by the "best scientific estimates" produced by regional bodies collecting tuna catch statistics (i.e. ICCAT, IOTC, SPC and IATTC).
