Effects of supplemental selenium in diets of Heterobranchus longifilis
The effect of selenium supplementation into diets of Heterobranchus longifilis fingerlings was investigated using a completely randomized design with triplicates in a mini-flow through experimental system. 245 fingerlings (mean wt., 1.5~c0.23g) were stocked and fed either normal (Basal) diet (Control group) or diets supplemented with 0.16, 0.24, 0.32 or 0.64 mg sodium selenite Kg-I Selenium addition to the diets and fed to the fish caused a significant increase (P<0.05) in weight gain and fingerlings growth rate was accelerated by 18-22% compared to 17-18% in the control group. There were significant differences (P<0.05) in survival rate between treatments, indicating that diets are likely to be responsible for increased survival rate, observed in fish fed diets supplemented with 0.24 and 0.32 mg Na2 Se03 5H2O kg-1 diet. Results indicated that a diet supplemented with, 0.24 and 0.32 mg of sodium selenite Kg-1 diet is important for growth and survival of H. longifilis fingerlings.
