Alien Species of Fish Helminths of Belarus

摘要

The article provides data on the species composition of alien helminth species which infest introduced fish species in pond fish farms and also published data on natural water bodies of Belarus. Seven alien helminth species have been revealed in introduced fish in water bodies of Belarus (Khawia sinensis Hsu, 1935, Schyzocotyle acheilognathi (Yamaguti, 1934), Caryophyllaeus fimbriceps Annenkova-Chlopina, 1919, Philometroides cyprini (Ishii, 1931), Dactylogyrus dulkeiti Bychowsky, 1936, Bothriocephalus claviceps (Goeze, 1782), Anguillicola crassus Kuwahara 1974). All species of helminths excluding the nematode A. crassus and the cestode B. claviceps, parasites of the eel Anguilla anguilla, were introduced to Belarus with the stocking material of Cyprinus carpio haematopterus (Linnaeus, 1758) from the Far East. The invasive species of helminths (K. sinensis, S. acheilognathi, P. cyprini, A. crassus), which affect the fishery by causing the death of farmed fish, are distinguished.
