Nile tilapia (Oreochromis niloticus) fingerlings with average weight of 4.01.0 g were used to investigate the growth performance of tilapia fingerlings fed with partially replacement of raw and boiled mung bean seeds meal (Vigna radiata) within six weeks of feeding trial. Three practical diets containing with or without raw and boiled mung bean seeds meal were formulated to replace soybean meal (SBM). The dietary treatment consists of Diet 1: control contained 30 % SBM; Diet 2: raw mung bean seeds meal (RwMB) contained 21 % SBM with 25 % RwMB and Diet 3: boiled mung bean seeds meal (BoMB) contained 21 % SBM with 25 % BoMB. Thirty tilapia fingerlings were randomly distributed into nine aquariums filled with 32 litres of dechlorinated tap water with double aeration. Fish were fed at 5 % of average body weight for three times daily. The best growth performance and feed conversion ratio (FCR) were observed with tilapia fed Diet 3 (14.97 g; 2.00), Diet 2 (13.47 g; 2.08) and Diet 1 (10.11 g; 2.54). Similar result were also obtained for specific growth rate (SGR) where Diet 3 had higher SGR (2.76 % day-1) compared to Diet 2 (2.62 % day-1) and Diet 1 (1.91 % day-1). Diet 2 contained boiled mung bean seeds meal had the best growth performance were compared with fish fed on control and raw mung bean seeds meal diet. Combinations of two or more techniques were required in inactivation of some anti-nutritional factors in legumes.
