Seasonal dynamics of the extent of the infestation of the vendace by the cestode Proteocephalus exiguus (Cestoda, Proteocephalidae) in Karelia

In two lakes of Karelia the infection dynamics of vendace (Coregonus albula L.) with the cestode Proteocephalus exiguus (La Rue) was studied in the summer-autumn period. 2006 specimens of vendace were dissected. Regularities of variations in the infection extensiveness depend on ecological characters of a water body and are modelled by various polynomes.
