Seven experimental diets (30% crude protein and 402.48±1.44 kcal/100g GE) were formulated to replace 0.0, 15, 30, 45, 60, 75 and 100% of soybean meal protein (SBM) as plant protein source by mung bean seed (MBS). Nile tilapia fry with an average initial weight (0.5±0.09 g/fish) were stocked at a rate of 15 fry/fiber glass tank (7 experimental diets x 3 replicates (21 fiber glass tanks)) and fed with those diets for 14 weeks to evaluate the growth performance, feed utilization and apparent

The highest values of dry matter, protein, fat and energy intakes were recorded by the control and 15% MBS group with significant differences (P<0.05) compared with the other treatments groups. On the other hand, significant differences (P<0.05) among groups for ADC% of CP, EE, NFE, DM and energy were observed with increasing rate of MBS more than 15%. There are significantly differences (P<0.05) for FCR, but contrary no significant differences for FER among all the groups. Apparently, there were no effect for all levels of MBS on chemical compassion (CP, DM, EE, GE and HSI) and survival rate. Incorporation of raw MBS more than 15% affected adversely on growth performance, feed utilization and ADC%. This may be due to anti-nutritional factors contents of MBS.
