Abstract

In the presented work are cited results of inspections an ecological condition of some lakes and rivers of Northern Kazakhstan. Zooplankton researches were spent to a summer season 2009 and 2010 on the river Ishim, the Sergeevsky reservoir and 17 lakes of the Northern-Kazakhstan area. The estimation of an ecological condition and the trophic status of reservoirs bioindication methods was the purpose of the spent work. As a result of research it is shown that the most part of the investigated lakes and considerable sites of the river Ishim, including the Sergeevsky reservoir, are in an unsuccessful ecological condition, a zoocenosis in them are transformed, the dominating complex of a zooplankton is very poor in the specific relation. As a part of a zooplankton predominate as a rule eurybiontic species, which have wide ecological lability. The part of the lakes, including having the fishing status, is infected with ectoparasite Ergasilus sieboldi Nordmann. The potential of self-cleaning of lakes and the river isn’t definitive yet, however additional nature protection actions are necessary for restoration of the safe ecological status.
