Digestive processes of 250-day-old white sturgeon were analyzed for enzyme concentrations, protein content and pH. Digestion is initiated in the gastric region by secretion of acid and pepsin; however, diversity of digestive enzymes is highest in the post-gastric alimentary canal with the greatest proteolytic activity in the spiral valve. Domination of the enzyme complement by proteases is consistent with this species carnivorous feeding habits.
对250日龄白鲟的消化过程进行了分析，检测了酶浓度、蛋白质含量和pH值。消化过程在胃部区域通过胃酸和胃蛋白酶的分泌启动；然而，消化酶的多样性在胃后消化道中最高，螺旋瓣中的蛋白水解活性最强。蛋白酶在酶组成中占主导地位，这与该物种的肉食性饮食习惯一致。
