RÉSUMÉ

Dependence between the content of the micronuclei inclusions in the mature erythrocytes of the round goby (Neogobius melanostomus Pallas) and intensity of erythropoietic processes in the blood-forming tissue was studied. It was shown that the proliferative activity of the erythroid blastema of the blood-forming tissue in this species increased with the organism approach to spawning, that is transition from the III-IV to V and VI-II stages of the gonad maturity. This was confirmed by increase of the of immature erythroid forms' content (basophilic and polychromatophilic normoblasts) in the fish blood. Simultaneously content of the mature red blood cells with micronuclei inclusions increased. Pronounced correlation between these processes was determined (R2 = 0.995), indicating that high proliferative activity of tissues may result in increase of the percentage of the DNA damages, that is formation of the micronuclei in the cells. Consequently, application of the micronuclear test to estimate the degree of genotoxicity of the marine environment in practice requires account of the natural state of the organism.
