In this study, Beluga Huso huso were cultivated with Chinese carp and common carp. The experimental period were 5 month (from May 21 to October 22, 2016) in a two hectare earthen pond in the Shahid Beheshti rearing and propagation center, Rasht, Guilan, Iran. Four floating cages (5×5×2 m3) were prepared and set up. Afterwards, 350 beluga were randomly distributed in the 4 cage in 2 treatment with 2 replication. Treatments including T1 (n: 100, density: 4.4 kg/m2, average weight: 1093.1±122.7 g, Average length: 69.7±0.4 cm) and T2, (n=75, density: 5.4 kg/m2 average weight: 1808.3±173.5 g, Average length: 75.4± 4.4 cm) reared in pond with common carp cyprinus carpio, grass carp Ctenopharyngodon idella, silver carp Hypophthalmichtys molitrix and bighead carp Hypophthalmichtys nobilis with initial biomass 50, 40, 40 and 20 kg/m2, respectively. At the end of experiment, average weight of beluga in T1 reached from 1093.1 ± 122.7 to 3382 ± 112.2 and in T2 1808 ± 173.5 to 5913.1±321.6 g respectively. Result indicated that increasing density lead to increasing the biomass, weight gain (WG), body weight increase (BWI) and specific growth rate (SGR) and decreasing of feed efficiency ratio (FCR). At the end of experiment, average weight of common carp, grass carp, silver carp and bighead carp were 1590.5±262.7, 2130.41, 16706.36 and 2650.66 ± 2630.6 g and the final biomass were 3578.7, 766.8, 1202.24 and 1170 kg respectively. The highest biomass increase were observed in grass carp. The result of this study showed that the integrated culture of beluga and Chinese carp in the earthen pond is possible and investment in this case is recommended.
