The PSMA is the first legally binding international agreement to tackle illegal, unreported and unregulated<\/a> (IUU) fishing.<\/p>\n\n\n\n For one year following its negotiation in 2009, the agreement was open for countries to sign up to. These signatory countries had then to ratify the treaty, by sending a formal document to the UN Food and Agriculture Organization (FAO), and becoming an official party to the treaty. Countries that did not sign up to the PSMA during the one-year period can still become a party to it, but this process is termed \u201cacceding\u201d rather than ratifying. The obligations for both groups are identical.<\/p>\n\n\n\n In June 2016, enough countries had become official parties for the PSMA to come into force.<\/p>\n<\/div><\/div><\/div>\n\n\n\n A UK-led study of 2017 data found<\/a> 14 of the world\u2019s 15 busiest ports to be in China, based on total number of vessel visits. The country also has one of the world\u2019s largest<\/a> fishing fleets, according to research published by the UN in 2022. This fisheries footprint makes crucial China\u2019s participation in improving the system being used to address illegal, unreported and unregulated (IUU) fishing.<\/p>\n\n\n\n Dialogue Earth asked four experts how important China\u2019s PSMA accession is to tackling IUU fishing, and what concrete changes they want to see next.<\/p>\n\n\n\n China\u2019s entry into the PSMA could be a major turning point in the fight against illegal fishing, particularly if they extend their vessel oversight to domestic fleet landings in accordance with the PSMA.<\/p>\n\n\n\n Research<\/a> has shown that China has some of the highest levels of risk in terms of its ability to effectively combat IUU fishing, making it more likely for IUU-caught fish to reach the marketplace, via its processing plants or directly. But by acceding to the PSMA, China has committed to strengthening ports and improving oversight of its fishing vessels.<\/p>\n\n\n\n The significance of this cannot be overstated, especially given the vast size of China\u2019s domestic fleet. More than 99% of visits to Chinese ports are from Chinese vessels. Moving forward, when its vessels return to their home ports, they will be subject to more robust inspections, and this additional check could make a large dent in the global effort against IUU fishing.<\/p>\n\n\n\n China is one of the world\u2019s largest fishing, processing, importing and exporting countries, with many ports along its coast. China\u2019s accession has significantly expanded the coverage of the agreement and improved the effectiveness of combating global IUU activities, by preventing illicit catches from landing and circulating through ports.<\/p>\n\n\n\n As a member of the PSMA, China should also cooperate with other member states to ensure that Chinese fishing vessels abide by a port state\u2019s regulatory measures while using foreign ports. We expect China\u2019s move will encourage more non-member states to follow in its footsteps.<\/p>\n\n\n\n While preparing to join the agreement, China has not only gradually strengthened its regulatory capabilities for its ports used by foreign fishing vessels, but also raised the management standards for its domestic fishing ports. That means following the approach of \u201cmanaging vessels at ports\u201d, by implementing systems requiring vessels entering and exiting<\/a> ports to declare their catch, gear, etc.; and making them land their catch at designated ports<\/a> with more enforcement capacity.<\/p>\n\n\n\n Joining the PSMA is crucial for China\u2019s sustainable fisheries transformation. To ensure an effective implementation of the PSMA\u2019s measures, China needs to continue to invest in enhancing its fishery management, cross-departmental law enforcement, and catch traceability.<\/p>\n\n\n\n China can actively cooperate with other member states in strengthening the capacities of implementing the PSMA, by exchanging technological knowledge and experience in law enforcement, etc. The country can also support and encourage more nations to join the PSMA and push for a wider port state supervision network.<\/p>\n\n\n\n The PSMA is a comprehensive approach to solving IUU fishing: no port entry, no market!\u00a0China\u2019s move on the PSMA crystallises its obligation to regulate fishing vessels and support solutions to IUU fishing globally.<\/p>\n\n\n\n In West Africa, fisheries ensure food security, livelihood support and revenue generation. Its thriving industrial fishing sector has been taken over by foreign-owned or foreign-controlled vessels.<\/p>\n\n\n\n Locally flagged, Chinese vessels are often also registered and licensed in China to benefit from government subsidies. At best, Chinese fleets in other jurisdictions will now be motivated by best practices, although the responsibility of upholding the PSMA is primarily borne by port states [signed up to the agreement].<\/p>\n\n\n\n All six countries of the Fisheries Committee for the West Central Gulf of Guinea (FCWC<\/a>) \u2013 Benin, Cote d\u2019Ivoire, Ghana, Liberia, Nigeria and Togo \u2013<\/strong> have joined the PSMA. These countries share fisheries resources, and by sticking together, they seal gaps in the fight against IUU fishing.<\/p>\n\n\n\n I expect China will step up to join in the PSMA efforts to clamp down on IUU fishing. The country\u2019s move will complement regional enforcement strategies and, in the long term, guide practices of Chinese vessels in other jurisdictions.<\/p>\n\n\n\n It is positive that China has joined the PSMA. This agreement is one more piece in a series of measures needed to combat IUU fishing. The success of this agreement also depends on new members joining.<\/p>\n\n\n\n The Chinese fishing fleet in Latin America comprises over 700 vessels. Many of them frequent the ports of Montevideo in Uruguay, and several others in Peru, according to data available on Skylight<\/a> and Global Fishing Watch<\/a>. Although these two countries are members to the PSMA, the fleet is thought to choose these ports because of the absence of controls, and low costs. Likewise, reports<\/a> show that the Chinese fleets are now actively looking for new ports in South America that are close to their fishing grounds.<\/p>\n\n\n\n Therefore, the countries in the region that have not yet joined the PSMA, notably Argentina, must do so soon. This will allow them to request information and actions to prevent IUU fishing from the other PSMA members.<\/p>\n\n\n\nElaine Young<\/h2>\n\n\n\n
