June 6, 2022 — One of the biggest challenges facing the global ocean is illegal, unreported and unregulated (IUU) fishing. Operating outside the constraints of laws, quotas and licences, IUU vessels commonly overfish, trawl in protected waters and take protected species.
IUU deprives countries of an estimated $26–50 billion annually. It depletes fish stocks and damages biodiversity, while threatening livelihoods and food security. It often takes place in developing coastal states that lack the governance and resources to monitor and protect their fish stocks effectively. More widely, IUU is linked to labor abuses, human trafficking and slavery.
To respond to these threats, in 2016 the UN Food and Agriculture Organization (FAO) brought into force the first legally binding international agreement to tackle IUU fishing. So how does the Agreement on Port State Measures (PSMA) work, and what has it accomplished so far?
What is the PSMA?
The vast majority of wild-caught marine fish are landed in ports. The PSMA enables nations that are party to it – of which there are currently 70 – to use ports as a form of border control for foreign-flagged vessels. The treaty applies not only to fishing vessels, but also those that transfer catch and refuel at sea. Guided by the PSMA, port officials assess the risk that an incoming vessel may be engaged in illegal activities, and decide whether to let it dock.
By tightening port controls, in principle the PSMA shuts out vessels that profit from IUU activities, and slows the flow of illegal fish into global markets. Enforcing at ports is also safer and more economical than patrolling the high seas looking for vessels fishing illegally. The idea is that as more nations adopt the treaty and turn away vessels engaged in IUU, they will be forced to travel further and at greater expense to land their catch, until it’s no longer profitable, and they are deterred.
