Information is given about the biotic condition of Lake Vashozero (southern Karelia) and the introduction
of new fish species in the lake is evaluated. By the water chemical composition the lake belongs to the hydrocarbonaceous class, by the hydrobiological criteria – to the mesotrophic type. Zooplankton biomass in the summer season is 3.6 g/m3, in autumn – 1.5 g/m3, benthos biomass in
the autumn season is 2.5 g/m2, i.e. feeding conditions in the lake are favorable for both planktivorous and benthivorous fishes. As regards the introduction of coregonids, positive results were obtained for the vendace, which has adapted itself to the new lake and is reproducing successfully.
