In present study, we investigated and compared serum biochemical (Calcium, Magnesium, Total Protein and Glucose) levels in three groups of female Persian sturgeon (A. persicus). The gonadal maturation was determined by gonadosomatic index (GSI). There was significant difference among GSI in three groups of female Persian sturgeon (P<0.05). The lowest GSI belonged in immature female and the highest GSI belonged in mature females. The result showed that, there was significant difference among calcium, total protein and glucose levels in three groups of female Persian sturgeon (P<0.05). Calcium level in maturing females (2.86±0.78 mg/dl) was higher than in immature (0.29±0.12 mg/dl) and mature females (0.07±0.05 mg/dl). While, total protein level in mature female (6.71±0.87 g/dl) was higher than in immature (2.37±0.28 g/dl) and maturing females (2.81±1.13g/dl). The level of glucose in maturing, immature and maturing females was measured 132.63±12.98 mg/dl, 118±3.7 mg/dl and 78±0.29 mg/dl, respectively. No significant difference observed in magnesium concentration of three groups of female Persian sturgeon (P>0.05).
