Introduced into Europe in the 19th century for aquaculture and sport-fishing, the North American brown bullhead Ameiurus nebulosus and black bullhead A. melas are often deemed undesirable due to competition and predation on local fish species. These non-native species may have an advantage over natives due to loss of natural pathogens, but may also serve as hosts for local parasites. In this study, we evaluate bullhead catfish from intensive aquacultural ponds, sport-fishing grounds and unmanaged water bodies in the Czech Republic (Central Europe) to determine whether they host co-introduced parasites infectious to local fish species and whether they serve as reservoirs for veterinary-important parasites. One-third of all parasite numbers were of North American origin, including Ictaluridae-specific monogeneans and myxozoans with a low risk of switching to local fish. Bullheads were confirmed as hosts for 26 taxa acquired in their new range, exhibiting significant infection with local Diplostomum spp. and Argulus foliaceus at high prevalence and abundance, especially in aquacultural ponds. Bullheads also showed high susceptibility to non-native Asian parasites, including larvae of the eel nematode Anguillicola crassus and the recently expanding ergasilid copepod Neoergasilus japonicus, these two representing almost half of all parasites found. Parasite infection had no obvious impact on host condition indices, and type of locality had no effect on physiological parameters, though it significantly influenced parasite community composition. While co-introduced parasites pose low risk to local fish fauna, bullheads serve as reservoirs for a wide range of local parasites, including both invasive and native veterinary-important species.
