SUMMARY S ixty-five eels (Anguilla anguilla) collected in the period between January-May 2008, from Al Salam channel (15 cases), Zagazig markets (17 cases) and Al Manzala Lake (33 cases) were examined for pathological lesions induced by parasitic infestation with identification of the causative parasite. The prevalence of pathogenic parasites (single or mixed infection) was 22 out of 65 eels (33.85%). The identified parasites were Anguillicola crassus (7 cases) (10.7 %), Dactylogyrus species (4 cases) (6.1 %), Pseudodactylogyrus species (5cases) (7.7%), Myxidium species (2 cases) (3.07%), Trichodina species (3 cases) (4.6 %), and Proteocephalus species (one case) (1.5 %). It could be concluded that the parasitic fauna markedly impairs the Egyptian eel's production and produce mild to severe degenerative, necrotic and inflammatory changes in the affected organs.
