Węgrzynowicz R., Marczuk K., Kłyszejko B., 1972. Osmotic fragility of erythrocytes of bream Abramis brama (L.) from Zalew Szczeciński. Acta Ichthyol. Piscat. 2 (1): 95-100.
Studies on erythrocytes fragility of bream Abramis brama (L.) originating from Zalew Szczeciński proved that maximal hemolysis takes place in solution of 0.25% NaCl and minimal in 0.55%. The curves of erythrocytes osmotic resistance are of sigmoidal profile. Visual density in any concentrations lower then 0.25% NaCl corresponds to decreasing osmotic fragility proportionally to progress of dilutions.
