Morphological Changes in Erythrocytes of Prussian Carp, Carassius gibelio (Bloch, 1782) during Long-term Exposition of Copper (Cu)

Morphological changes in erythrocytes of Prussian carp (Carassius gibelio) during long-term exposition of copper and recovery period were studied. We examined the percent of normal erythrocytes, deformed erythrocytes and dividing cells in the blood smears. It was found that influence of long-term exposition in concentration of 0.05 and 0.1 mg/l rose up rate of deformed erythrocytes and these changes disappeared during recovery period. We found different morphological changes in the erythrocytes like tearing to peaces of cell membrane and changes in size and form of cells and their nucleus.
