Despite increased efforts by law enforcement agencies across Europe, the illegal trade in endangered European eels continues to pose a significant threat to the species. Europol has conducted multiple high-profile busts of eel smuggling rings, resulting in the arrest of hundreds of smugglers and the seizure of millions of euros worth of smuggled elvers. The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) has recognized Europol's success in Operation Lake, a coordinated international effort to combat the trafficking of glass eels, but ongoing action is still needed to prevent the extinction of the European eel.
