Zoogeographical Analysis of the Fish Parasites from Lake Hövsgöl

Abstract

The composition of the fish parasites of Lake Hövgöl has been analyzed for the first time based on the authors’ data and literary data from the perspective of available contemporary results of the studies on the taxonomy of individual groups. The parasite fauna of 9 fish species of Lake Hövgöl is represented by 73 species, of which protozoa and myxosporidia have 10 species each; monogenes 25, cestodes 11, trematodes, and nematodes 5 each; acanthocephales and leeches 2 each; and crustaceans 3. The species composition of the parasites of Hövgöl fish is represented by a smaller number of species-rank taxa compared to that of Lake Baikal and the Yenisei and Ob rivers. The fish parasites fauna of Lake Hövgöl belongs to 3 faunal complexes: boreal plain, boreal submontane, and arctic freshwater. In general, it corresponds to the parasite fauna of the Arctic province of the Palearctic. Parasites of the boreal submontane faunal complex dominate (48.2%).
