The relationship between the contents of abnormal erythroid forms (dacryocytes, nuclear invagination, and erythrocyte ghosts) and the number of immature erythrocytes (pronormoblasts, as well as basophilic and polychromatophilic normoblasts) was studied in the circulating blood of round gobies. It was found that the proliferative activity of the erythroid branch of blood-forming tissue in this species increases as the gonads mature, i.e., during transition from the III–IV to the V and VI–II stages of gonad maturity. The content of poorly differentiated cells in the blood grew by 26%, while the number of abnormal erythrocytes (dacryocytes and nuclear invagination) decreased by 3 or 4 times (R 2 > 0.95). The content of erythrocyte ghosts, in contrast, increased by 80%. When evaluating the toxicity level of the marine environment, not only the number of abnormal erythrocytes in fish blood but also the activity of the blood-forming tissue should be taken into account, as it substantially varies during the spawning period.
