[SOME FEATURES OF THE BIOLOGY AND PARASITE FAUNA OF THE ARCTIC CHAR (SALVELINUS ALPINUS L.) IN THE LAKE MUSHTALAMPI...

The native population of the Arctic char in the Lake Mushtalampi was studied. The dwarf form of the Arctic char inhabiting the lake was revealed. The fish is characterized by extremely low growth rate and by early maturation. Twelve parasite species were found in the arctic char. The parasite fauna is typical of representatives of Salmonidae. Distinguishing features of this fauna include the absence of narrowly specialized char parasite species. High intensity of infection with nematodes Philonema oncorhynchi allows estimating the epizootic state of the studied char population as insufficient.
