It was found that the red corpuscles of the teleosts studied increased their size, when the salt concentration of the hypotonic solution spproached the threshold concentration where the hemolysis of the corpuscle begins. In this case, the oval form of the natural red corpusele was deformed into the round one. In hypertonic (5%) NaCl solution, however, the dwindled red corpuscle appeared (Table 1).
In contrast to other fishes; shark red corpuscle was found to become larger than the normal corpuscle even in the hypertonic solution. In the case of the sea water, fishes, the hemolysis of the red corpuscle took place at the higher concentrations compared to the case of the fresh water fishes.
By estimating the dissolved hemoglobin in terms of the optical density, the hemolysis curve was easily obtained (Figs. 1 & 2).
