title: Productivity and biomass of trematode (Digenea) parasites in lake ecosystems.
abstract: The first estimation of the annual production and biomass of cercariae (free swimming transmission stage of digenetic trematodes) in a lake ecosystem has been performed. The biomass of cercariae is comparable with that of free-living invertebrates and may make a significant contribution to the energy flow in lake ecosystems.
