Abstract :
Blood parameters are often used as indicator for stress and health condition evaluation in fishes. The aim of this study was to compare blood and biochemical indices between stellate sturgeon (Acipenser stellatus) and Common Carp (Cyprinus carpio). In total, 20 brood stock fish (including 10 of each species) were selected and their blood samples were taken. Results showed that the mean counts of red blood cells (RBC), white blood cells (WBC), percentage of haematocrit (Hct), level of hemoglobin (Hb), cholesterol and osmolarity in Common Carp was more than Stellate sturgeon, although no significant difference was observed(P≥0.05). Differential count of leucocytes showed that the mean lymphocyte percentage in A.stellatus was more than C.carpio, while there was no significant difference seen in percentage of neutrophiles, Eosynophiles and monocytes in C.carpio compared with A.stellatus (P≥0.05). Mean level of Glucose in C.carpio was significantly more than A.stellatus (P≤0.05). On the other hand, mean level of triglyceride, albumin and total protein in A.stellatus was significantly more than C.carpio (P≤0.05). Cytomorphological parameters of RBC such as cell area, nucleus area and MCV in A.stellatus was significantly more than C.carpio. Therefore, the levels of some blood parameters were different in stellate sturgeons (Acipenser stellatus) in comparison with Common Carp (Cyprinus carpio), that can be related to their development differences.
