As the unique one in Tuna RFMOs(Regional Fishery Management Organizations)which has established High Seas Boarding & Inspection Procedures, Western and Central Pacific Fisheries Commission (WCPFC) promotes compliance by Commission members with conservation and management measures through carrying out the High Seas Boarding & Inspection. Since 2006, some countries and areas started to board and inspect fishing boats successively in West and Central Pacific high seas, the parties taking part in the procedures and the times they implement the procedures increased with years. Strict high seas boarding & inspection brings great challenges to conduct responsibility of China's tuna fishing activities. In order to ensure the sustainable development of China's tuna fishery in WCPFC waters, we summarized evolution and development of WCPFC High Seas Boarding & Inspection, analyzed the implementation and characteristics of WCPFC High seas Boarding & Inspection since the execution, and explored the categories and causes of the violations of Chinese fishing boats through studying related China cases of High Seas Boarding & Inspection since 2011. We put forward suggestions that the government, enterprises, associations and scientific research units should enhance the capacity of Chinese tuna fishery together, reduce violations of rules by fishing boats and fulfill relevant international obligations.
