Abstract
As a result of integrated studies carried out at the end of August - September 2008-2010, the ichthyofauna and food reserve for fish in Lake Oiskoe (the Ergaky Range) was investigated. The trophic status of the lake was estimated on the basis of the biomass of phyto-, zooplankton and zoobenthos. Relying on calculations of average biomass and production per season for zooplankton and zoobenthos, estimations of potential ichthyomass, fish production and possible fishing amount were estimated.
