Freshwater eel populations are plummeting globally, but a major international push for stronger trade protections was just defeated, with the United States and Japan leading the opposition—raising urgent questions about the future of sushi, global seafood supply, and biodiversity protection.
The Eel Crisis: A Modern Extinction Tale Under Our Noses
Eels—evolutionary survivors since the era of dinosaurs—are teetering toward catastrophe. These mysterious, snake-like fish are more than a curiosity. For cultures worldwide, they’re a seafood delicacy and a key ecological indicator. But populations of the critical anguilla genus—responsible for the world’s supply of freshwater eel—have plummeted, with some species declining by over 90% since the 1980s.

Sushi at Risk: Why Freshwater Eel Matters to Global Consumers
The anguilla eels occupy a crucial place in the international sushi industry, especially in Japan, where dishes like unagi have deep cultural roots. Baby eels—or elvers—are harvested at high value, providing seed stock for Asian aquaculture. With wild stocks collapsing in Europe and Asia, the economic and conservation weight has shifted to American eels, whose numbers are falling but not as catastrophically.
- Maine is the only US state with a significant legal elver fishery, strictly regulated and fiercely protected.
- Elvers fetched over $1,200 per pound in 2024 at Maine docks, down from more than $2,000 a pound the year before, illustrating the global demand-and-scarcity cycle.

The Global Showdown: Conservation vs. Seafood Economics
The dire status of eel populations led the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) to propose tighter export restrictions for anguilla eels—including new permit requirements and enhanced monitoring. CITES is a key treaty in international wildlife protection, and its measures have proven effective, as seen in past protections for European eels since 2009.
But resistance was strong. At this week’s decisive summit in Uzbekistan, a coalition of fishing groups, seafood companies, and government regulators from the United States, Japan, China, and South Korea argued that national laws were sufficient and that further trade restrictions would not fully address black-market poaching or the multi-factor causes of eel decline.
In a pivotal vote, CITES members rejected the proposed new rules. Critics called the effort “an international body dominated by volunteer scientists and unelected bureaucrats.” Japan and the US, both major markets and traders of eel, led the opposition.
Eel Protections Defeated: What Happens Now?
New international rules would have forced exporters to prove that eel trade isn’t causing ecological harm and that harvested eels weren’t illegally caught, closing loopholes in global enforcement. This is significant because illegal poaching remains rampant, with rare species often misdeclared in trade channels [AP News].
Conservationists argue that stronger international trade oversight is critical to arrest the decline before wild eel populations crash completely. They also highlight eels’ broader ecosystem importance: as indicator species, their fortunes reflect the health of rivers and coastal systems worldwide.
Stakeholder Gridlock: Industry Fights Back
Fishing industry representatives warn that excessive regulation could harm legal fisheries without stopping smugglers. US regulators maintain that American laws and quotas provide adequate safeguards. Asian industry and regulatory bodies, citing incomplete evidence tying international trade directly to population loss, echoed this perspective.
- Japan and China both rejected CITES’ bid to list anguilla eels as protected, prioritizing economic and cultural factors.
- US fisheries managers claim existing enforcement deters overexploitation.
- A multinational seafood coalition stated that trade is not the sole cause—and that regulatory focus should be broader.
The Broader Risk: Why Eel Decline Matters for Everyone
While not universally loved, eels are a crucial part of aquatic food webs. Their disappearance could signal disruption across entire river and wetland ecosystems, and highlight the world’s failure to balance cultural foodways with urgent conservation.
The controversy over eel trade and protections encapsulates a wider dilemma: can international agreements override economic self-interest to stem biodiversity loss? With global seafood demand surging and climate pressures mounting, the defeat of new protections for anguilla eels sets a precedent—and a warning.
What’s Next?
In the absence of new global rules, responsibility for eel survival falls to national and regional management—amid uncertain effectiveness and intense black-market demand. Consumers, regulatory agencies, and the seafood industry must now wrestle with whether to maintain, boycott, or transform the eel trade before its subject disappears from the world’s waters and plates.
