    Abstract:
    The role of a bicarbonate buffer system of fish (Cyprinidae family) blood was studied in their organism addaptive reactions to different levels of CO2 in the aqueous medium. The fish is established to prossess rather effective for maintaining blood acid-base balance. It permits the fish to endure for a long time essential fluctuations of carbonic acid concentration in water. In prevention of possible development of carbonic acid acidosis an essential role belongs to formation of bicarbonates as a blood buffer system stablizing pH is shown to be significant for preventing possible development of acidosis. The adaptation potentialities of Cyprinidae family permit them to endure an increase of CO2 in water and are determined by the ability of their organism to formations of bicarbonate and their retaining in blood.
