数十亿欧元走私贸易威胁欧洲鳗鱼存亡

欧洲鳗鱼种群正面临灭顶之灾。自1980年代以来，欧洲鳗鱼数量下降了约95%，已成为濒危物种1。这一生态危机的背后，是一条蔓延至欧洲、北非和亚洲的非法走私网络，年利润估计达30亿欧元1。

走私贸易的主要目标是玻璃鳗——欧洲鳗鱼的幼体。这些刚孵化的鳗鱼在黑市上身价高昂，价格达9000欧元每公斤1。犯罪集团利用玻璃鳗在普通行李箱中可存活48小时的特点，将其从西班牙等欧洲国家走私往亚洲市场1。走私路线已从西班牙扩展到摩洛哥、毛里塔尼亚和塞内加尔等北非国家1。

虽然西班牙巴斯克地区已实施捕捞禁令以保护该物种，欧盟也自2010年起禁止该物种出口到欧盟外，但非法贸易仍然猖獗1。执法部门加大了打击力度，Europol的Lake行动在2024-2025年间缴获22吨玻璃鳗，逮捕26名嫌疑人1。然而，面对如此庞大的利润空间，犯罪集团不断适应执法措施，走私手段和路线日益复杂1。鳗鱼从萨尔加索海迁徙到比斯开湾期间，仅有约12%的幼体能够存活1，这使得任何非法捕捞都对这一物种的恢复构成致命威胁。

Europe's eel populations have declined by approximately 95% since the 1980s, pushing the species toward extinction and fueling a lucrative illegal trafficking network 1. Glass eels, the juvenile form of European eels, command prices reaching 9,000 euros per kilogram on the black market, generating an estimated 30 billion euros annually in illegal profits 1. Despite protective measures including an export ban implemented by the European Union in 2010 and fishing restrictions in Spain's Basque region, criminal networks continue to exploit the species across increasingly complex smuggling routes 1.

Law enforcement agencies have intensified efforts to combat the trade. Europol's Lake operation seized 22 tons of glass eels and arrested 26 suspects between 2024 and 2025 1. However, traffickers adapt quickly to enforcement pressure, with smuggling routes now extending from Spain through North Africa—including Morocco, Mauritania, and Senegal—to Asia 1. The biological vulnerability of the species compounds the crisis: only approximately 12% of eel larvae survive the journey from the Sargasso Sea to the Bay of Biscay, while glass eels can remain viable in ordinary luggage for up to 48 hours, facilitating their transport 1.
