The effect of direct predation by fish on cercarial populations of selected trematode species (Digenea)
 HEINCLOVÁ, Pavla
The predation effects of four fish species on the consumption of free-living cercariae of three trematode species (Plagiorchis elegans, Echinoparyphium aconiatum and Trichobilharzia szidati) were experimentally investigated with regard to specific life-history traits of both predator and parasite. The study provides evidence of a considerable consumption of trematode cercariae by fish and confirms that cercariae play an important ecological role in the energy flow in aquatic food webs.
