Species diversity of metazoan parasites in the recently established freshwa
ter population of the tubenose goby (Proterorhinus marmoratus) in the Czech
Republic was studied.
Thirteen parasite species were found (Diplostomum spathaceum, Tylodelphys c
lavata, Apatemon cobitidis proterorhini, Proteocephalus sp., Pseudocapillar
ia tomentosa, Raphidascaris acus, Camallanus lacustris, Anguillicola crassu
s, Philometra ovata, Acanthocephalus lucii, A. anguillae, Glochidium sp. an
d Argulus foliaceus). The most prominent feature of species diversity is th
e extremely low infection rate of parasites with the exception of digenean
metacercariae. The parasite infracommunities consist of one to five species
, in twenty-nine combinations. The highest frequency of infracommunities fo
rmed of two and three parasitic species was found. In infracommunities, dom
inant elements are usually metacercariae of digeneans, other parasitic spec
ies are only satellites. Metacercariae of digeneans infect fish in their ju
venile stage of development, other parasitic species were found in fish of
standard body length of 35-36 mm and larger, that is age 1+ and more.
On the basis of analysis of parasite biodiversity and their infection rates
, we conclude that the process of acquiring local parasites in the tubenose
goby is still not completed. The tubenose goby is serving as definitive or
paradefinitive host for four parasite species, as obligatory intermediate
host of four, and as paratenic host of five helminth species.
