Digestive enzyme complement of white sturgeon (Acipenser transmontanus).
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.
