Between January 2020 and April 2026, the Yong Xiang 9 had at least 340 likely transshipment meetings. Its most frequent partners include Jia De 15, Pu Yuan 805, Zhe Pu Yuan 77, Heng Xin 1, and Pu Yuan 820.

Transshipment occurs when fishing vessels offload their catch to a refrigerated carrier that transports it to port, rather than the vessel going itself. Reefers can haul catch from multiple fishing vessels at once, which makes supply chain tracing difficult.
