The deep-sea smelt Bathylagus euryops, caught in July 2004 at the Charlie-Gibbs Fracture Zone (CGFZ) of the Mid-Atlantic Ridge (North Atlantic), was studied for metazoan parasites and diet composition. A total of 86 specimens with standard lengths between 6.4 and 22.1 cm (mean 13.6 cm) were examined. The parasite fauna consisted of five species: three Digenea, one Cestoda and one Nematoda. The predominant parasites were Lecithaster sp. (Digenea) and an unidentified bothriocephalidean cestode. The only nematode, Anisakis sp., occurred with a low prevalence. Bathylagus euryops at CGFZ serves as final host for the three digeneans, and as intermediate host for the cestodes and Anisakis sp. Stomach content analysis revealed a mesozooplankton crustacean diet, while 95.3% of the stomachs contained unidentified tissue.
