CHANGES OF SOME HEMATOLOGICAL INDICATORS IN ROACH YOUNG RUTILUS RUTILUS L. FED WITH FOOD CONTAMINATED WITH POLYCHLORINATED BIPHENYLS AND ORGANOCHLORIDE PESTICIDES
The number of micronuclei, amitotic index and leukocytes balance were investigated in peripheral blood and immune competent organs of one year old roach fed with stuffing of fishes captured in the Sheksna and Molozh stretches of water in the Rybinsk reservoir ( concentration of PCB in the feed was 50.8 ng/g and 3.7 ng//g,dry weight accordingly). Data obtained prove PCB mutagenic activity and show non-specific response of fishes protective systems to the pollution.
