Comparative analysis of the osmotic resistance of erythrocytes in different in the ecology Teleostei
The comparative analysis of the indices of the resistance of erythrocytes to the hemolysis in different representatives of Teleostei is carried out. The dependence of this parameter from the water salinity, method of nourishment and mobility of fishes, seasons, reproductive phase of fish and age of erythrocytes is studied. It is established that reduction in the water salinity as a whole is correlated with reduction in the stability of the erythrocytes of fishes to the hemolysis. The considerable variability of the resistance of the erythrocytes is revealed in fresh-water fishes, with a difference in the parameter of resistance being correlated with the ecological features of fishes. As a whole, the obtained results allow to assume that differentiation of the erythrocytes of fishes in terms of the parameter of osmotic resistance is influenced by such factors, as the salinity of water, the means of life, nourishment, reproductive phase and stage of ontogenesis. The seasonal changeability of the resistance parameters of erythrocytes, most probably, is a result of the combination of these factors. Refs 30. Figs. 4.
