The aim of the present work was to investigate the helminth fauna of commercially caught gobiid fishes (Zosterisessor ophiocephalus, Neogobius melanostomus, N. fluviatilis, N. syrman) of the Budaksky Lagoon. The studied fish harbored nine parasite species that include three Holarctic species, one Euro-Siberian, one Cosmopolitan species, one Boreo-Atlantic species, one Mediterranean species, and two Ponto-Caspian ones. The most widespread species were: Cryptocotyle lingua, C. convacum, Acanthocephaloides propinquus. Two Ponto-Caspian cestod species: Proteocephalus gobiorum, Ligula pavlovskii are specific for gobiids. Possible reasons of the infection variability were discussed. Eight species of helminths have been recorded for the first time in the Lagoon.
