Statistics Working Group

History of ISC STATWG

In 1996, ISC1 recognized the importance of collecting and archiving data for stock assessment purposes, and established a working group to address fisheries data collection, data processing and data distribution matters. Japan assumed the leadership of the Statistical Working Group (STATWG) and guidelines for addressing fisheries statistics were developed. The guidelines were approved at the ISC2 Plenary in 1999.

The first STATWG meeting was held on January 18-19 1999, chaired by Dr. Gary Sakagawa, with participants from Japan, Mexico, United States, Chinese Taipei, IATTC and SPC. The group reached agreement on the provision of historical Category I, II, and III data on an annual basis.
