چکیده
  The salinity tolerance, hematological and hydromineral regulation capabilities of juvenile Russian sturgeon (Acipenser gueldenstaedtii) were investigated in different ages and sizes in freshwater (FW: 0.05) but differed in experimental media (p < 0.05). Signifi cant differences were observed between the levels of plasma ion concentrations in different media (p < 0.01). Plasma Na+, K+ and Ca+2 concentrations were higher than those of FW media, but lower than in CSW media (p < 0.05). Plasma Mg+2 concentrations were lower than those of FW and CSW media, but near to EW media (p < 0.05). The hematocrit mean cell volume decreased but mean cell hemoglobin concentration, osmolarity and levels of plasma cortisol were increased from FW media to CSW media (p < 0. 05). The hemoglobin concentration (Hb), the amount of hemoglobin per erythrocyte, red and white blood cells count did not change (p>0.05). However, the results showed that the above parameters in fish fingerlings did not return to initial values in the new environment and then physiological changes happened.
