The potential effects of stocking densities (1, 2, 4, 6 and 8kg/m-2) of Beluga (Huso huso)
was investigated on water quality and growth factors of the fish. Feed was offered three times
daily using a commercial diet to the juvenile fish at the average initial weight of 93.13±1.04g
(±SE) for a period of 8 weeks. The final biomass was 4.0, 6.5, 11.0, 14.5, 17.1kg/m-2 from the
lowest to the highest densities, respectively. At the termination of the experiment, the mean
weight reached 362.4±6.9, 319.7±2.1, 267±9.2, 242.1±6.2 and 211.1±4.1 in densities of 1 to
8kg/m-2, respectively. Results of the present study showed that growth parameters, including:
Final weight (W), body weight daily (BWD), weight gain (WG), condition factor (CF) and
feed efficiency (FE) had significant differences among the treatments (P0.05). Results showed that stocking densities have major effects on water quality and
growth indices of Beluga juveniles.
