Occurrence of Atractolytocestus huronensis (Cestoda, Caryophyllaeidae) in German pond-farmed common carp Cyprinus carpio.

Up to now, the caryophyllid cestode Atractolytocestus huronensis Anthony, 1958, a parasite of common carp, has attracted little attention in Germany. Based on recent publications from the Czech Republic and Hungary, it appears probable that this cestode may be increasingly common in Germany. There is a strong connection between the occurrence of A. huronensis and imports of common carp from the Czech Republic and southern Germany. Although in most cases no clinical alterations in parasitized carp have been observed, care should be taken to avoid further dissemination and to prevent possible losses in commercial pond farming.
