| The effects of dietary Schizochytrium sp. supplementation on morphological characters and growth performance of Nile tilapia (Oreochromis niloticus) were studied. Fish (initial weight 84.08-84.26 g) were fed with pelleted feed (30% crude protein) supplemented with Schizochytrium at 0% (control group), 2.5%, 5.0% and 7.5% and reared for 8 weeks. Results were shown that body depth gain and dorsal width gain of fish fed 7.5% Schizochytriumhad the highest values (2.58±0.19and1.00±0.11 cm), which was significantly higher (P<0.05) than the control group. The average weight gain of fish fed 7.5, 5.0 and 2.5% Schizochytrium were162.75±9.79,132.19±12.66 and 113.87±18.39g, respectively, and were significantly different (P<0.05) from the control group which was... |
