        1 - The Comparatision of Blood Indices on Farmed Stellate Sturgeon (Acipenser stellatus) and Common Carp (Cyprinus carpio)

        Blood parameters often are used as indicator for stress and health condition evaluation in fishes. The aim of this study was to compare the blood and biochemical indices between stellate sturgeon (Acipenser stellatus) and Common Carp (Cyprinus carpio). In total, 20 broo More
        Blood parameters often are used as indicator for stress and health condition evaluation in fishes. The aim of this study was to compare the 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 blood samples were taken. Results showed that mean levels of red blood cells (RBC), white blood cells (WBC), haematocrit (Hct), hemoglobin (Hb), cholesterol and osmolarity in Common Carp were more than Stellate sturgeon and showed no significant difference (P>0.05). Differential count of leucocytes showed that mean level of lymphocytes percent in A. stellatus was more than C.carpio, whileneutrophile, Eosynophile and monocyte in C.carpio were morethan A. stellatus with no significant difference (P>0.05). Mean level of Glucose in C.carpio was significantly more than A. stellatus (P<0.05). Mean levels 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. The results indicated that the levels of some blood parameters were different between stellate sturgeons (Acipenser stellatus) in comparison with Common Carp (Cyprinus carpio) which can be related to their difference in development levels.

        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.
