ABSTRACT
The Chinese sleeper Perccottus glenii Dybowski, 1877 is an invasive fish species rapidly expanding in Siberia and Europe. Its native range encompasses the Far East region of Russia, northeastern China and northern North Korea. We studied species composition, prevalence, mean abundance and variance of mean abundance of macroparasites of the Chinese sleeper in the native and the introduced range. The species composition of the parasite component communities differed considerably in the native and the introduced range. The frequency distributions of prevalence, mean abundance and variance of mean abundance of the parasites did not demonstrate any significant differentiation between the two parts of the host range. However, an analysis of the abundance-occupancy and the abundance-variance relationships revealed that the parasite component communities in the two parts of the host range were quite distinct. In the native range, prevalence increased faster and variance increased more slowly with the increasing abundance of the parasites than in the introduced range. These features are mostly associated with considerably increased prevalence, abundance and aggregation of the host-specific cestode Nippotaenia mogurndae in recipient water bodies as compared with the native habitats.
