Palia (Salvelinus alpinus f. lepechini) belongs to salmon fishes (Salmonidae). It is one of the species that are under the threat of disappearance. Palia is a freshwater form of the complex species "arctic loach" (Salvelinus alpinus L.) that inhabits across the coast of the Arctic Ocean, from Iceland to Chukotka. In the lakes of Karelia there are two species of palia - palia red ("ludnaya", shallow) and palia grey ("yamnaya", deep-water). Parasite fauna of palia was compared in several lakes of the Baltic Sea (the Onega Lake, the Ladoga Lake) and the White Sea (Pyaozero). The greatest variety of parasites was discovered in the Onega Lake (20 species). 15 and 9 species inhabit Pyaozero and the Ladoga Lake correspondingly. In comparison with the other water basins palia in the Ladoga Lake is less infected with Cestoda. Palia in the Onega Lake is greatly infected with Cestoda Eubothrium salvelini, Diphyllobothrium dendriticum and Triaenophorus nodulosus. Monogenia Gyrodactylus salaris and copepoda Salmincola edwardsii are typical of this lake. Parasite fauna of palia in Pyaozero (the White Sea) is similar to the fauna of the Ladoga Lake (small number of Cestoda, great number of worms). The worm Echinorhynchus salmonis is the most widely spread species there (100%, average intensity - 132 worms) that demonstrates very intensive consumption of pontoporeia. The results of the research show that the parasite fauna in the lakes of the similar trophic status includes the similar species of parasites. Eutrophication of Ladoga has grately changed its status and led to reduction of the parasite fauna.
