Transshipment at high seas is very difficult to monitor, allowing the possibility of illegally caught fish to enter the legitimate seafood market, or enabling human rights abuses. This paper uses AIS data to track global transshipment behavior. They find that a majority of transshipment occurs at high seas outside of EEZ boundaries–areas that may lack national jurisdiction or where regulations are difficult to enforce. Additionally, possible transshipment encounters are happening with vessels flying flags of convenience. Together, these findings paint a scene of large transparency issues in global transshipment behaviors that will need to be addressed by governing bodies.
