In order to evaluate some biological and physiological qualities of the broodstock of Russian sturgeon (Acipenser gueldenstaedtr), blood factors consisting of albumin, hematocrit, hemoglobin, red blood cells (RBCs) an white blood cells (WBCs); germinal vesicle and fertilization rate in 27 females broodstock (17 specimens showed no respond to the hormone injection) and 13 males broodstock {B specimens showed no respond to the hormone injection) were investigated. Results showerʹ that the average levels of RBCs, WBCs, hematocrit, hemoglobin, lymphocytes and eosinophiles were higher in both female and male broodstock where positively respond to pituitary hormone injection. Also, average percentage of fertilization, hatching and total number of produced larvae were 68.2%, 38.6% and 6 x 105, respectively. Therefore, based on present results, it is possible to identify the appropriate broodstocks using mentioned parameters, in particular the level of eosinophiles and metaeosinophiles as well as determination of germinal vesicle.
