Tracking Refrigerated Transshipment Vessels to Inform the FAO's PSMA

This paper highlights the use of transhipment activities to hide IUU fishing. Transshipment allows fishing vessels to stay at sea; sometimes for years at a time and has been linked to transnational crime and human rights violations. The Agreement on Port State Measures to Prevent, Deter and Eliminate Illegal, Unreported and Unregulated Fishing (PSMA) is a binding international treaty of the United Nations’ (UN) Food and Agriculture Organization (FAO).
With growing participation in the PSMA AIS data can be utilised to better inform the decision making process and implementation. This paper discusses the methodology and application of AIS which offers reliable and accessible information regarding port visits that has previously been difficult to obtain.
