Abstract
1181 yearlings of pelyad (Coregonus peled) and its hybrids with Siberian (Coregonus lavaretus pidschian) powan were dissected. A calculation of loss in mass per 100 kg of catch at different levels of fish infection with metacercariae of diplostoms was made. Losses increased in direct proportion to the average number of metacercariae per 1 g of mass of fishes. With 1.5 metacercariae per 1 g of mass of fish population losses amounted to 1/2 of potentially possible production.
