Abstract

Nineteen of 20 fish species were infected by A. crassus larvae, but prevalence and intensity of infection varied widely. Ruffe Gymnocephalus cernuus and European catfish Silurus glanis showed the highest prevalence of infection (100%), followed by river goby Neogobius fluviatilis (83%), white bream Blicca bjoerkna (79%) and bleak Alburnus alburnus (68%). Of these 13 fish species, ruffe showed the highest intensity of infection by live larvae (mean intensity: 39.3 3rd stage larvae, L3), followed by catfish (mean number of live larvae: 26.9) and river goby (mean number of live larvae: 9.1). Bleak play the most important role in the transmission of the anguillicolosis. Other intensively infected fish species (eg ruffe) may also contribute to massive infection of individual eels Anguilla anguilla, even if they have a lower share in the eels' food structure. -from Author
