A find of Argulus coregoni (Crustacea: Branchiura) on brook trout in the Western Dvina basin

Abstract

The crustaceans Argulus coregoni Thorell, 1864 were found on the body surface of brook trout Salmo trutta m. fario L., 1758 in the Velesa River (tributary of the Western Dvina River, Tver Oblast, Russia). This is the first finding of A. coregoni in the Western Dvina basin, which shows that this species can parasitize on specific hosts in the upper reaches of small rivers.
