Distribution Not yet found in Scotland and Wales. Found in most European countries except Ireland [details]alien species The swim-bladder nematode, Anguillicola crassus, parasitizes the swim-bladder of the European eel (Anguilla anguilla). This small nematode has a Japanese origin. It reached Europe in the 1980’s through infected Japanese eels, Anguilla japonica, imported for eel farming. The first Belgian observations date from 1985. Since then, the species is very common in both wild European eel specimens, as in the eel farms. Infected eels do not grow as well, are generally less fit and - in extreme cases – the infection can lead to the death of the eel. [details]
