Abstract—The effect of the prelethal state on functional properties of hemoglobin has been studied in the goldfish Carassius auratus. A considerable decrease in hemoglobin affinity for oxygen and the Bohr effect values and the change in the shape of the curve of oxygen equilibrium have been detected. Such state may be compared to the effect of strong short-term stress.

Keywords: goldfish Carassius auratus, hemoglobin affinity for oxygen, Bohr effect, death
