Popis: Specific parasite, cestode Nippotaenia mogurndae, can be found in both small and large individuals of the introduced fish Perccottus glenii. This phenomenon is difficult to explain because fish are infected by swallowing plankton crustaceans (copepods). Copepods are consumed by small P. glenii whereas large fish of this species feed on bigger prey. The period of life of N. mogurndae in P. glenii intestine is limited; therefore accumulation of the parasite is impossible. We tested the hypothesis that N. mogurndae infection of large P. glenii could occur by cannibalism. Large P. glenii (collected in water body without N. mogurndae) were fed with small P. glenii (collected in water body with N. mogurndae). After 5 days, these fish were examined and N. mogurndae was detected in their intestines. Thus, large P. glenii can be infected by cestode N. mogurndae through cannibalism.
