A rearing experiment was conducted for a 12 weeks period to investigate the effects of dietary tricalcium phosphate (TCP) on young red sea bream in aspects of growth, feed utilization and bone mineralization. The fish fed the diet with a low level (0.2%) of Ca supplement from TCP (diet 2) showed growth similar to the fish fed 0.2% Ca from Ca-lactate (diet 1). Fish fed the diet with a high level (2.5%) of Ca supplement from TCP (diet 3) showed significantly poor growth than the fish fed diet 1. Feed efficiency and condition factor were lower in the fish fed diets 2 and 3 compared to diet 1. TCP in the diets 2 and 3 decreased the Zn content of bone. These results indicate that inclusion of a high level of TCP to the purified diet decreases the growth, feed efficiency and Zn content of bone in red sea bream
