The research was realized in the conditions of the Republic of Belarus in 2011-2013 in the National park ‘Narochanskij’ (Minsk region). There is available the data on hydrochemical conditions of water reservoir prior and after establishing cage culture fishery line, development of phyto and zooplankton, level of biogenic stress introduced. There was shown that the main contamination of ecological system is caused by the fodder used and fish metabolite, but sufficient amount of dissolved forms of mineral phosphorous even the excessive increase of mineral nitrogen does not cause structural recombination of trophy elements of the water reservoir.
