Effects of eel restocking on the distribution of the swimbladder nematode Anguillicola crassus in Flanders, Belgium

Abstract

Data on the distribution in 1986 of the parasitic nematode in the swimbladder of the European eel (Anguilla anguilla L.) in Flanders (Belgium) are reported. In stations where imported eels have been used for restocking, samplings generally show high infection rates thus enhancing the spread of Anguillicola crassus in Flanders.
