Details on the transport of European eel larvae through the Strait of Gibraltar into the Mediterranean Sea.

Numbers of European glass eels (Anguilla anguilla) monitored along the Atlantic and Mediterranean coasts of Europe currently serve as the main stock indicator in assessment of this critically endangered species. Spawning, however, takes place exclusively in the Sargasso Sea, several thousand kilometers away. The beginning of its complex lifecycle is characterized by a distant and lengthy larval drift, before the young-of-the-year reach the monitoring stations at the European coasts.
