Abstract

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).
