The European Eel, Anguilla anguilla, is a snakelike fish. They are generally believed to spawn in the Sargasso Sea and the larvae (Leptocephalus) migrate towards Europe in a three-year-long migration. They enter freshwater, where they spend their lives. The slimy coating of the eel is thought to protect the fish against changes in salinity. from nl wikipedia With consent of the photographer, see also nl: wikipedia image with the pos fish. ...

Since the 1970s the numbers of eels reaching Europe is thought to have declined by around 90% (possibly even 98%). It is unclear whether this is part of a normal long term cycle, or whether this reflects a decline in eel numbers generally. Potential causes include overfishing, pollution, parasites such as Anguillicola crassus, river barriers such as hydroelectric plants, and natural changes in the North Atlantic oscillation, Gulf Stream and the North Atlantic drift. This article provides extensive lists of events and significant personalities of the 1970s. ...
