| Effects of Schizochytrium sp. on growth performance and survival rate of Nile tilapia, Oreochromis niloticus, juveniles were studied. Fish (initial weight 2.27-2.30 g) were fed with commercial pellet feed (32% crude protein) supplemented with Schizochytrium sp. at 0 (control group), 2.5, 5.0 and 7.5% for 8 weeks. The result showed that average weight gain of the 7.5, 5.0 and 2.5% Schizochytrium sp. supplemented were 37.84+1.227, 32.81+0.648 and 31.17+0.226 g, respectively, which were significantly different (P<0.05) from the control group (28.11+2.393 g). The Schizochytrium sp. supplemented fish had the average daily growth rate was significantly higher (P<0.05) than the control group but there was no statistically significant difference among... |
