Illegal, unreported, and unregulated (IUU) fishing and associated crimes are undermining coastal communities throughout Latin America and the Caribbean – hurting the economic wellbeing of licit fishers and reducing coastal and ocean biodiversity, fish stocks, and food security. The EU and the UN Food and Agriculture Organization (FAO) have made ending IUU fishing a priority because it contributes to overfishing, enables labor abuses, and violates international norms on sovereignty and biodiversity.
IUU fishing comprises a diverse slate of illicit acts, including foreign vessels fishing in another country’s sovereign waters without permission; disregard for international environmental laws; and inadequate catch reporting to state authorities. Illicit actors include large distant-water fleets (DWFs) backed by states like China, Taiwan, and Japan as well as individual locally based artisanal vessels with small crews.
- Latin America represents only 2.1 percent of global aquaculture production, but its losses to IUU fishing – losses that experts estimate to be $2.3 billion a year – make it the third-hardest hit continent. According to a 2020 study by the Fisheries Economics Research Unit and the Sea Around Us organization at the University of British Columbia, income losses are as high as $600 million, and tax revenue losses are as high as $300 million dollars, with the other $1.4 billion owing to the general redirection of catches from legitimate to the illicit seafood trade.
- Costa Rica has seen by-kill of young fish from the use of illegal nets as well as incursions by illegal fishermen in its offshore national parks. Until recently, Ecuador faced a flotilla of as many as 340 Chinese vessels catching and storing marine life around the Galapagos Islands. In Jamaica, depleted seafood stocks have pushed local fishers into deeper waters, where there is a risk of collision with IUU fishers searching for diminishing sources of conch and lobster. In Suriname, IUU fishers have been known to steal the nets of domestic fishers.
IUU fishing often involves forced labor and other crimes, further harming coastal communities and billions of people worldwide whose economies and diets are tied to fish. By undercutting legal market prices, it threatens the livelihood of licit fishers who pay fair wages and don’t have the same technological advantages.
- Overfishing reduces supplies for local communities. The FAO estimates that total fish consumption in Latin America and the Caribbean will increase 33 percent by 2030 (more than any other region). Overfishing by IUU actors has already forced the Dominican Republic and Jamaica to increase imports of fish and seafood and impose new catch quotas that, when expanded in other countries, would likely affect the more than 3 million people in the region who work in fishing or aquaculture.
- Related crimes are committed by artisanal fishers operating in coastal waters, where they illegally harvest seaweed, pursue endangered species, fish in the off-season, or engage in smuggling; domestic industrial fishers who misreport catches; and DWFs that use flags of convenience to trick authorities.
- IUU fishers threaten biodiversity because they are heavily skewed toward immediate predation, with little concern for the long-term economic impact and environmental costs. They also complicate states’ fishery sustainability efforts, making implementation of the UN Sustainable Development Goal to eliminate IUU fishing fall far behind. In addition, shark finning is prominent in Costa Rica, Ecuador, and Chile despite domestic and international laws against it. Nine of the 12 shark species found aboard a Chinese IUU freighter off Ecuador in 2017 were endangered.
The regulatory frameworks for fighting IUU fishing are weak; enforcement tools are lacking; and most countries lack the resolve to address the problem. The current international framework includes a hodgepodge of international and national agreements and initiatives, without the active engagement of many of the world’s largest fishing nations.
- The cornerstone is the Agreement on Port State Measures (PSMA), which binds signatories to reduce illicit fishing by denying IUU fishing vessels access to port services and to lessen access of illicit catch to international markets. International bodies such as the FAO provide tools for tracking vessels, but regional fisheries management organizations (RFMOs) and advocacy groups like Oceana say that there is only limited sovereign commitment to the rules. Some of the most seriously affected countries are those with the fewest resources to combat the problem.
The combination of IUU fishing and related crimes, such as labor abuses and copy-cat practices by local fishers, pose threats to national economies, food security, and ultimately regional stability. What’s needed is obvious: enhanced monitoring, control, and surveillance capacity; updated legal instruments and increased judicial sanctions; and more resolute multilateral action on fishing subsidies and ocean protection. One question is whether the victims of IUU fishing themselves can muster the national and regional resolve to address the problem – sacrificing the short-term gain of permissiveness for the long-term goal of protecting strategic interests. Without that resolve, Latin America and the Caribbean will continue to be victimized by IUU fishing and the inequality, labor abuses, resource exploitation, and violations of national sovereignty it enables.
