This work evaluated the inclusion of several levels of canola meal in ration used in the development and carcass compositions of juvenile Nile tilapia (Oreochromis niloticus L.), Chitralada strain. Were used 15 polypropylene boxes, with 310 liters (10 fish each). The fish were fed with five isonitrogenous (28%) and isocaloric ration (2900 Kcal EM/kg), twice a day for six months. The canola meal was used in four levels (TT = 0%, T1 = 8%, T2 = 16%, T3 = 24% and T4 = 32% / diet), in a completely randomized design, with 5 treatments and three repetitions each. The data obtained were submitted to variance analysis (ANOVA) and the averages compared by the Tukey test (p0,1) on fishes body composition, however had best body weight gain with canola meal on levels 16% and 24%. These values seem to show that for the Nile Tilapia, Chilatrada strain, the use of canola meal is viable when included in up to 24% of the diet, without any performance loss.
