Abstract

This study was carried out on 24 farmed Huso huso (8 males and 16 females) in the international Sturgeon Research Institute during 3 years. Samples were collected based on different sexual maturation stages. Results showed that hematocrit (PVC), hemoglobin (Hb) and red blood cells (RBC) was more in males than females and increased in both them related to sexual development especially at stage IV. Mean corpuscular volume (MCV) and Mean corpuscular hemoglobin (MCH) showed no significant difference between males and females, but Mean corpuscular hemoglobin concentration (MCH) showed significant increase in males and females related to sex development. White blood cells (WBC) were lower significantly in males than females and showed no significant difference at different sexual stages. The most percentage of leucocytes belongs to lymphocyte, neutrophile, eozynophile and monocytes and increase with sexual development without significant difference. There was no basophile. Results of this study showed that blood indices profile in Huso huso was similar to others sturgeon species and some parameters were dependent on sex and sexual maturation stages.
