This report analyzed the movements of carrier vessels operating in the Western and Central Pacific Fisheries Commission (WCPFC) Convention area in 2016. Through analysis of AIS data, the report identified carrier vessel voyage patterns and quantity, carrier vessels' flag state patterns, the spatial distribution of potential transshipment on the high seas, and the port visit locations by carrier and flag states. The report also found that many carrier vessels did not transponder on AIS, leading to significant gaps in data on unreported transshipment events. Ultimately, the WCPFC’s management of transshipment in its Convention area is compromised by a lack of reported information on transshipment, coupled with non-compliance with reporting requirements and non-standardized reporting responses by CCMs on carrier vessels and their activities.

The Western and Central Pacific Fisheries Commission (WCPFC) has seen a staggering growth in transshipment activity within its Convention Area. Using publicly available information on transshipment
operations within the WCPFC, the WCPFC provides an analysis of transshipment and recognizes the need for additional management rules on transshipment within its Convention Area. Their analysis shows flaws in managing transshipment events and sharing and reporting data between other RFMOs and within their own carrier observers. Implementation of the best practices developed by the Pew Charitable Trusts could be a solution to this issue.
