Abstract
The new data on the parasites fauna of the Lake Kronotskoe sympatric charr forms (genus
Salvelinus (Nilsson) Richardson, 1836) is presented. Parasites fauna of Bigmouth and
Smallmouth charr forms are described for the first time. The information about Longhead
charr, Nosed charr and White charr parasites is added. 29 species of parasites from 9 classes
were found: Oligohymenophorea, Myxosporåà, Monogenea, Trematoda, Cestoda, Nematoda,
Acantocephala, Crustacea and Hirudinea. Longhead charr was the most intensively
infected by Proteocephalus longicollis (Zeder, 1800) (abundance 306.0) and Neoechinorhynchus
salmonis Ching, 1984 (abundance 230.0). White charr was mostly infected by
Crepidostomum Braun, 1900 (abundance 242.2) and P. longicollis (abundance 183.4). Nosed
charr group that feed on gammarids was infected mostly by Crepidostomum spp.
(abundance 3461.3), Cyathocephalus truncatus (Pallas, 1781) (abundance 179.9) and Cystidicola
farionis Fisher, 1798 (abundance 169.0); while Chironomidae consumers group
was infected mostly by Diplostomum Nordmann, 1832 (abundance 62.3) and Phyllodistomum
umblae (Fabricius, 1780) (abundance 27.3). Bigmouth charr was infected mostly by
P. longicollis (abundance 17.0) and Eubothrium salvelini Sñhrank, 1790 (abundance 11.0),
Smallmouth charr form — by P. longicollis (abundance 67.0) and Diplostomum sp. (abundance
64.2). Sympatric flock of charrs form the Lake Kronotskoe (Kamchatka) is the most
polymorphic for the genus Salvelinus in Eurasia. According to the parasitological analysis
this flock consists six ecological forms.
