Endoparasitic helminths of fishes in three alpine lakes in France and Switzerland

A systematic survey of endoparasitic helminths of 9 species of fishes from three Alpine lakes, Annecy, Bourget (both France) and Geneva Lake (Switzerl and and France), is presented. Eleven species of intestinal helminths (2 Di genea, 7 Cestoda, 1 Nematoda and 1 Acanthocephala) were found in 272 of 372 (i.e. 73%) fish species examined. The dominant parasites were pseudophylli dean tapeworms Eubothrium crassum (Bloch, 1779) and E. salvelini (Schrank, 1790) in lake trout (Salmo trutta m. lacustris) and Arctic char (Salvelinus alpinus) respectively, and the proteocephalidean Proteocephalus longicolli s (Zeder, 1800) in whitefish (Coregonus lavaretus).
