N2 - A 3×4 factorial experiment was conducted for 45 days to determine the effects of diets containing different levels of protein and fat on growth of fingerlings Beluga (Huso huso L.1758). Twelve different diets were formulated with 3 levels of protein (45,50 and 55) and 4 levels of oil including fish oil and sunflower oil (0.5 ,4 , 8 and 12). 1260 Beluga fingerlings with an initial body weight (IBW) of 2.2 gram, after adaptation to the experimental conditions, were selected and stocked randomly into 36 fiberglass tanks (100 water volume) at 35 fish per tank, and fed on experimental diets for 45 days. Two ways analysis of variance showed that the percentage of body weight increase (%BWI), specific growth rate (SGR),protein efficiency ratio (PER), food concumpsion ratio, and productive protein value (PPV) content were significantly (P SP - 229 EP - 242 AU - E.
