Abstract: The analysis of micronucleus frequency in fish caught in the Kazakhstan part of the Caspian region in the territories of Mangistau and Atyrau regions was carried out. We determined the component composition of sediment samples in the field of fish catch. Fish from carp family was subjected by micronucleus analysis. The nature of violations indicates that in some places, anthropogenic pressure has chemical and radiological component. It noted the correspondence between the cytological and cytogenetic abnormalities in fish erythrocytes and the results of content of man-made pollutants in samples of sediments taken in the trapping field of test animals.
