摘要: Summary This study tried to determine the protein and energy requirements of growing beluga sturgeon Huso huso using a factorial approach. The experiment was composed four small-scale growth trails covering different weight ranges. fish fed at 0, 20, 40, 60, 80 100% satiation. DWG had steady increase throughout following non-linear equation as Y = 1.433 (±0.056) · Ln(X) )2.740 (±0.261); r 2 0.99, p < 0.001, where gain (g/day) X (g). daily requirement digestible (DE) for maintenance amounted 79.09 kJ BW (kg) 0.8 . DP calculated 0.93 g 0.7 relationship between DE intake (X) (Y) expressed )0.0004 (±0.000) + 0.600 (±0.082) )44.95 (± 6.72). Also, Y= )0.019 (±0.006) 0.548 (±0.062) ) 0.498 (±0.121). were estimated 2.94 2.63 gain. Apparently, is inefficient in converting into body tissue. Therefore, content diet should be sufficiently high satisfy large demands also reduce catabolism protein.
