Data are presented on the parasite fauna of the European eel, Anguilla anguilla (L.) in three coastal lagoons of the Ebro delta (NE Spain). Ten parasite species were found, four protozoans: Eimeria anguillae, Trichodinapediculus, Myxidium giardi and Myxobolus sp.; five helminths: Pseudodactylogyrus anguillae, Deropristis inflata, Bothriocephalus claviceps, Proteocephalus macrocephalus, Anguillicola crassus and one crustacean: Ergasilus gibbus. The highest prevalences were reported for P. anguillae 84.6%, M. giardi 44.4% and A. crassus 30.8%. Helminth communities were dominated by monogenean P. anguillae. These communities were compared with those from other European coastal lagoons.
