Аннотация:A long-term parasitological survey carried on the round goby, Neogobius melanostomus, from the Black Sea has revealed its high level of infection with anisakid juveniles. In previous studies, some of the juvenile stages of the genus Contracaecum were identified as C. microcephalum according to available identification keys based on morphology, although the latter species is considered more common in fresh-water habitats. Analysis of nucleotide sequences of LSU rDNA and ITS rDNA of Contracaecum juveniles from the round goby Neogobius melanostomus demonstrated their identity with the cryptic species Contracaecum rudolphii A of a species complex Contracaecum rudolphii Hartwich, 1964 sensu lato.
