Abstract
    In the Danube River, the stellate sturgeon population has declined dramatically from a numeric perspective. The screening of hematological parameters is regarded as a useful tool for assessing the health status of fish species. The objective of the study was to analyzing the parameters in the blood of genitors of the A. stellatus fishing for assessing the health status. Individual A. stellatus were anesthetized with MS222 and 3 ml of blood was sampling and analyzed with routine method used in fish hematology. Was determined: red blood cell counts (RBCc, x 106/µl), the hematocrit (PCV, %), the leukocrit (LK) and hemoglobin concentrations (gl/dl). Using standard formulas the red blood indices were computed: the mean corpuscular volume (MCV), the mean corpuscular haemoglobin (MCH) and the mean corpuscular hemoglobin concentration (MCHC). According to the present results, hematological values in males and females were: PVC 35,80 and 31,73 %, RBC count 1, 36 and 1,05 x 106/ L, hemoglobin 9.97 and 9.41 g dl-1, MCV 266,93.76 and 305.47 fL, MCH 74,33 and 89.98 pg, MCHC 27,83 and 30.55 g dl-1. The hematological values reported in this paper will be used as reference for monitoring of physiological and health status of A. stellatus from the Danube river.
