This study was performed to evaluate four common food rations in Iranian market on growth performance, some biochemical factors of farmed beluga (Huso huso) in winter 2015. Total number of 80 belugas weighing 4063.48± 134.29g were randomly distributed into 8 circular concrete ponds and kept at a density of 10 fish per pond. Fish were acclimatized to new rearing conditions for a week. Great sturgeons were fed four rations including Behdaneh, Biomar, Faradaneh and Skretting in two replicates (completely randomized design). Results showed that the highest final weight, percentage of body weight increase, average daily growth, specific growth rate, condition factor, protein efficiency ratio and the lowest FCR and price index were observed in treatment Faradaneh which had significant differences with treatment Behdaneh (P0.05). The highest content of cholesterol was seen in treatment Behdaneh which showed significant difference with other treatments (P
