[Monogenea in 2 species of fish of the order of the garfish (Beloniformes) from the Indian and Pacific Oceans].

Two fish species, Euleptorhamphus viridis and Cololabis saira, were studied for monogeneans. 284 specimens of E. viridis collected in nearly all parts of its area in the Indian and Pacific Oceans have been examined. Five species of monogeneans were found in this species: Axine parini, Axinoides kola, Diplaxine popovae and two species of gastrocotylid larvae. None of them were recorded in E. viridis before. In both oceans the infection of E. viridis with Axine parini and Gastrocotylidae g. sp. I larvae was the most extensive. In the Indian Ocean the infection extensiveness of E. viridis with A. parini was higher than in the Pacific. The areas of all parasites were more restricted than that of the host. None of 190 specimens of the saury had any monogeneans.
