Each diet was fed to triplicate groups of fish three times a day until satiation. The growth performances of fish fed diets included FPH were significantly (P<0.05) higher than those of fish fed the control diet. The survival ranges from 90 to 100%. In non-specific immune response of group, fish fed diets containing 5% FPH had significantly higher superoxide anion (O2-) than those feed other treatments. The fish fed diets containing 5% and 10% of FPH showed no significantly different SOD activity of liver, however their SOD activity of liver was significantly higher than that of other treatments.
In the second trial, the effect of partial replacement of fish meal protein by yeast meal in orange-spotted grouper diets was studied. 4.74±0.02g uniform-sized Epinephelus coioides were fed five isonitrogenous (45% crude protein) and isolipidic (9% crude lipid) diets containing different levels of yeast meal to replace 0%, 10%, 20%, 30% and 40% of fish meal protein, respectively for six weeks. Each diet was fed to triplicate groups of fish three times a day until satiation. The growth performances of fish fed diets included yeast meal were significantly (P<0.05) higher than those of fish fed the control diet. The SGR of fish fed diets containing 10%, 20% and 40% of yeast treatments were significantly (P<0.05) higher than control diet, however no significantly higher than 30% treatment. Survival rate of all treatments was 100%.
