Between January 2020 and April 2026, the Captain Mokeev had at least 486 likely transshipment meetings. Its most frequent partners include Ostrov Shikotan, Aniva, Vasiliy Kalenov, Kapitan Kolesnikov, and Iolanta.

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.
