efficiency of two rearing enviroments in culture and effect on growth perormance of beluga) Husohuso) were investigated. in accordance two group of three years husohuso ((Average weight of 9.93±0.305 and 10±0.5Kg) density ( 0.5 and 25 kg/m2)) with 3 replicate were stocked in two culture environmentand reared with formulated diet including protein 43% and energy 22 MJ/ kg for 12 month from 2014.6.19 to 2015.9.10 A.D .in the end of rearing period, indices of Final weight , final biomass, daily growth and body percent weight fish reard in cement tank (20.1±0.6, 2016.66±5.77, 0.112±0.00239 and 102.35±1.1 kg) were significanthly higher than fish reared in pond( 17.4±0.4, 1746.66±7.2, 0.082±0.118 and 74.15±4.71 kg) , respectively ) P<0.05). food efficiancy ratio between two group were not significantly diffeent (P >0.05). Result of this study indicated that except of primary cost of building Cement tank, Husohuso prebroodstocking in cement tank is better than pond for resultof increasing of growth, thrift in culture rearingand more effective management.
