Current state of the Pandozero Lake ecosystem, Kivach State Nature Reserve, Karelia

Ilmast N.V.  , Sterligova O.P., Kuchko Ya.A.

The composition of the benthic fauna of the fish population of Pandozero Lake (Onega Lake basin), located in the Kivach State Nature Reserve, Republic of Karelia, was studied. The abundance indices of its macrozoobenthos are consistent with an oligotrophic type of water bodies, and its chironomid index value with that of a moderately contaminated water body. The lake’s fish population consists of 13 species (6 families) dominated by perch, bream and roach. Valuable fish species, such as whitefish and pike-perch, also occur. Ide was found in the lake for the first time. The studies have shown that Pandozero Lake’s ecosystem is now in satisfactory condition.
