Five experimental diets were formulated to determine the effects of green pea meal (GPM) inclusion in the formulation on the growth performance of hybrid grouper (Epinephelus fuscoguttatus ♀ X E. lanceolatus ♂) juveniles. GPM was included at the expense of soybean meal (SBM) at 0 (GP0), 5 (GP5), 10 (GP10), 15 (GP15) and 20% (GP20) replacement levels, which are equivalent to 0, 3.2, 6.5, 9.7 and 12.9% of the diet. GPM used in the present study had a higher lysine content than fish meal or SBM. Overall, the GPM-based diets performed significantly better than the control. In particular, juvenile hybrid grouper fed GP10 yielded the best growth and feed utilization. Therefore, the use of GPM at 6.5% of the diet is recommended to improve growth and feed utilization of hybrid grouper juveniles.
