Abstrakt:	A 40-day feeding trial assessed the dietary protein and energy:protein ratio requirements for optimum growth performance of juvenile bluefin trevally,Caranx melampygus. Practical diets were formulated to contain 33%, 37%, 41%, or 45% crude protein and either 9 or 11 kcal GE/g. Dietary protein level at any given energy:protein levels significantly affected muscle protein, feed consumption, growth, feed efficiency, survival, and protein and lipid retention. At dietary protein levels >33%, increasing energy:protein ratio to 11 kcal GE/g protein significantly reduced growth performance and feed consumption. Results suggest that optimum growth and feeding response of juvenile bluefin trevally can be attained at a dietary protein level of 45% with an energy:protein ratio of 9 kcal GE/g protein.
