Abstract

The parasite fauna of the eel has been studied regularly since the first imported eels were introduced to Lake Balaton in 1963. Over a long period of time no important parasitic infections were recorded. However, the importance of nematode infections has increased since 1991, when the pathogenic nematode Anguillicola crassus was first detected and intensive eel mortalities started to occur. This paper reports on the first occurrence of Paraquimperia tenerrima, a small nematode infecting the gut of the eel. Paraquimperia tenerrima is a common parasite in rivers of several European countries. Due to the small size and the low prevalence of the worm its pathogenic effect upon eels seems to be negligible in Lake Balaton.
