Influences of food particle size on growth, size heterogeneity, food intake and gastric evacuation in juvenile Nile tilapia, Oreochromis niloticus, L., 1758

This study aimed at determining the food particle sizes (diameter) that produce the fastest growth (S opt) in juvenile Nile tilapia, and modeling the growth penalties for particles departing from S opt. Three 14-day experiments were run with 3, 7 and 11 g juveniles, which were raised in 120-L flow-t...
