EFFECT OF FEEDING PROTOCOL ON DAILY ACIDIC DIGESTION IN GILTHEAD SEABREAM JUVENILES

In fish species having a stomach the full acidic digestion capacity is attained when the transition to juvenile is completed (Yúfera et al. 2004). The pepsin is activated from its precursor at low pH gastric environment. Nevertheless, such low pH is only attained in some moments during the feeding and digestion process. The daily acidic digestion pattern basically depends on gut content and internal rhythms for the production of pepsinogen and HCl in the cells of the lumen of th
