European Eel Smuggling Fuels a Billion-Euro Black Market

The Core Trade and Its Scale
Criminal networks are moving millions of European eels—critically endangered and valued at up to €9,000 per kilogram—through complex routes that span from the Basque coast to Asian fish farms. The illegal market is estimated to generate €3 billion in peak years, with traffickers comparing the operation to drug trafficking. Florian Stein, head of policy and science at the German Angling Association, says the trade may involve up to 100 tons of glass eels annually, equivalent to roughly 300 million fish. Fines for organized groups can reach six times the value of the smuggled eels, making the risk-reward calculation attractive for criminal enterprises.
Biology, Decline, and EU Protection Measures
European eels migrate from the Sargasso Sea to European rivers, a journey in which only about 12 % of larvae survive to reach the Gulf of Biscay. Since the 1980s, the species has suffered a ?95 % population decline. The EU banned export of the eel outside the bloc in 2010, and member states must enable 40 % of adult eels to return to the Sargasso Sea to spawn. Marine biologist Estibaliz Diaz warns that additional measures—such as removing hydroelectric dams that kill migrating eels—are needed, noting the species may not have time to wait for long-term projects to take effect.
Smuggling Routes and Law-Enforcement Action
Historically, Madrid’s airport served as a major hub, but heightened inspections forced traffickers to shift to a North-African corridor through Morocco, Mauritania and Senegal. The Strait of Gibraltar’s narrow, busy waters make the route attractive. Europol’s Operation Lake seized 22 tons of glass eels and arrested 26 suspects between 2024 and 2025. Interpol’s Sanchez Romero reports sustained pressure from law-enforcement across Europe, prompting criminals to continually adapt their pathways.
Fishermen’s Opposition to the Ban
Local Basque fishermen argue that the regional ban penalises law-abiding anglers while organized crime profits. Unai Eizaguirre, a 30-year eel-fisherman, contends the restrictions threaten the community’s identity and livelihood, describing the situation as “ridiculous” and fearing the ban could hasten the species’ extinction.
