diet with higher water stability. The dietary inclusion of high water-stable soybean meal diet resulted in a 30.52% reduction in total feedintake relative to the control diet, which possibly suggests that aprolonged digestion process following ingestion and slower gas-tric evacuation rates could have resulted in reduced feed intakein the O. niloticus fed this diet. Aside gastric retention times, thehigher feed intake of the relatively lower water stable diets pos-sibly implies that O. niloticus are able to easily crush and handlethese pellets more effectively in their buccal cavity during feed-ing.
