Effect of different dietary protein and energy levels on growth of juvenile Beluga (Huso huso
A 2 à 4 factorial design was conducted to study the effects of dietary protein and energy levels on growth performance of juvenile beluga (Huso huso) with average weight of 49.85 ± 1.64 g. Experiments were conducted with two dietary protein levels (40 and 45%) and four dietary energy level (18.5, 1...

Experiments were conducted with two dietary protein levels (40 and 45%) and four dietary energy level (18.5, 19.8, 21.1 and 22.4 MJ/kg diet) by ratio P/E (18.03 to 24.14 mg/kj).

Growth of fish fed high- energy diets was significantly higher than those of fish fed low- energy diets at 40 and 45% dietary protein levels (P⤠0.05). Protein content of carcass increased when dietary protein increased, but there was no significant different (P⥠0.05) between 40 and 45 % protein.
