Evaluation of stocking density on water quality parameters in rearing of Beluga (Huso huso)
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 peri...

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.
