The effects of factors were evaluated with 2 or 4 levels in a factorial design using an orthogonal array L8. In Experiment I, the weight gain (%) was slightly higher (P<0.10) in small fish (about 0.36g) than in large fish (about 6.8g) but not significantly different with the feeding rates (1.5%, 3.5%, 5.5%, and ad libitum feeding) and dietary protein levels (25% and 35%). The FCE and PER were decreased with increasing feeding rates (P<0.05) and were higher (P<0.05) in small fish than in large fish but not significantly differed between 25% and 35 protein diets. In Experiment II, the weight gain (%) and PER were decreased with increasing dietary cellulose levels (2%, 7%, 12%, and 17%) (P<0.05) and were higher (P<0.05) on 35% protein diet than 25% protein diet. However, the feed consumption and FCE were not significantly variable with dietary cellulose and protein levels.}, pages = {7--15}, title = {Effects of Feeding Rate, Fish Size, and Dietary Protein and Cellulose Levels on the Growth of Tilapia nilotica}, volume = {36}, year = {} }
