Abnormalities in adult digeneans, with special reference to Phyllodistomum umblae (Fabricius) (Platyhelminthes, Gorgoderidae)
During examination of a large sample of Phyllodistomum umblae from Arctic char, Salvelinus alpinus , in Lake Tokke (Drangedal, type locality) and Lake Katnosa (Nordmarka, vicinity of Oslo), Norway, several abnormalities were found in the adult specimens. The paper describes the abnormal cases recove...
