Abstract: | Analysis of osmotic resistance of erythrocytes identified the similarity between marine and freshwater Teleostei and inclination
of erythrocytes from freshwater fish to intravascular haemolysis. Structural resistance of hemoglobin was significantly higher
in marine species and resistance to dehydration was significantly higher in freshwater fish. The resistance of erythrocytes
and hemoglobin in freshwater fish widely varyies depending on species’ inhabitation conditions. Several strategies for stabilization
of respiratory function in the blood of Teleostei were formulated as following: (1) a strategy of compensatory type in the
fish ontogenesis, (2) formation of different quality resistance to haemolysis of young and mature erythrocytes; (3) variability
resistance of hemoglobin to dehydration and (4) transformation of homeostasis of an organism in extreme conditions. |
