Comparative investigation of blood factors in wild Persian sturgeon, Acipenser persicus

In this study, measurement of blood parameters was carried out with the aim of evaluating the normal status of wild males and females Acipenser persicus blood parameters in the Sahid Beheshti reproduction and restocking complex during spawning season and comparing it with other sturgeon. Blood samples collected from 28 Acipenser persicus captured from the south coasts of the Caspian Sea for measuring WBC, RBC, Hematocrit, Hemoglobin mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), mean corpuscular hemoglobin (MCH) and differential count of leucocytes in males and females during 2007-2009. Results showed that mean RBC and WBC number of females was 833533.33±74505.54 and 11100±1211.81 mm3, respectively, that was lower than males with mean 996153.85±2910.60 and 11423.10±1019.31 mm3, respectively. Blood hematocrit percentage of males were lower than females that were 28.70±1.33 and 29.27±0.93%, respectively. Mean blood hemoglobin of males was lower than females that were 8.99±0.22 and 9.8±0.33g/dl. MCHC, MCH and MCV levels in males were 318.23±32.95 fl, 28.7±1.33pg and 97.92±7.9%, and in females were 334±20.30 fl, 115.2±8.13pg and 34.77±1.71%, respectively. Although total count of blood cells showed no significant difference in wild Acipenser persicus, but their percentage was different in males and females. Percentage of lymphocyte, eozinophile and neutrophile in males and females were 69.38±2.03, 75.80±3.01, 4.15±1.44, 3.47±0.7, 26.1±2.43 and 21.4±3.1 respectively. Therefore, regarding the results, blood parameters amounts of males and females Acipenser persicus brood stocks was similar to each other and was independent to sex
