Common sculpin Cottus gobio as a natural paratenic host of Proteocephalus longicollis (Cestoda: Proteocephalidae), a parasite of salmonids, in EuropeFranti$ek Moravec*Institute of Parasitology, Academy of Sciences of the Czech Republic, Brani$ovská 31, 37005 >eské Bude[caron]jovice, Czech RepublicABSTRACT: Common sculpins Cottus gobio L. (Pisces: Cottidae), from the Ml)nsk) Brook near >eské 5leby in the 2umava National Park, southwestern Bohemia, Czech Republic, were found to harbour in their intestines juvenile cestodes Proteocephalus longicollis (Zeder, 1800), a common parasite of holarctic salmonids, with a prevalence of 60% and intensity of 1 to 11 (mean 5) parasites per fish; undoubtedly, these prey fish serve as paratenic hosts. In this locality, the definitive host of P. longicollis is the brown trout Salmo trutta m. fario L., large specimens of which apparently acquire infection of this parasite by feeding on infected sculpins. C. gobio is the first known natural paratenic host of P. longicollis in Europe.
