Calculation of protein and energy requirements in beluga sturgeon ( Huso huso) using a factorial approach
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 of four small‐scale growth trails covering different weight ranges. The fish fed at 0, 20, 40, 60, 80 and 100% of satiation. DWG had...
