Sturgeons are an ancient group of chondrostean fishes with fossil records dating back to the Lower Jurassic period. They are among the highly endangered fish species because of overfishing for meat and caviar production, degradation of habitat, and spawning grounds along with environmental pollution. Huso huso is one of the most important species of sturgeon in the Caspian Sea [1]. This study was conducted to investigate the effects of dietary ginger, garlic, nettele (0 and 1%) on some blood parameters of Beluga (Huso huso) juveniles (25.1±۱.۹ g). The study was carried out on 80 Beluga. After 8 weeks feeding on the experimental diets, blood haematological parameters were measured. The results revealed that dietary ginger, garlic and nettele had no effect on leukocytes (WBCs) count, Hb and MCH index (p>0.05). However, HTC in fish, fed dietary ginger (25.92±۱.۲۵) and nettle (28.99±۱.۵۶) showed significant increase than control group (17.57±۱.۰۰) (p<0.05). Mean cell haemoglobin concentration (MCHC) in garlic group (47.01±۲.۰۳) significantly increased than control group (p<0.05) but in nettle group (22.31±۱.۲۷) this index showed significant decrease than control (p<0.05). Mean corpuscular volume (MCV) in garlic group (308.05±۲۹.۰۱) showed significant decrease and in nettle group (872.24±۱۱۹.۷۳) showed significant increase than control (753.69±۱۵۸.۱۹) (p<0.05). Red blood cell counts in ginger group (0.57±۰.۰۳) ×۱۰۶  showed significant increased than control(0.36±۰.۰۵) ×۱۰۶  .These results indicate that these herbal diet can improve some haematolgical parameters in Beluga which should be taken into account in future studies.
