Effects of dietary vitamin C supplementation on fingerling golden trevally, Gnathanodon speciosus (Carangidae)


Author(s): Do-Huu Hoang

Abstract: This purpose of this experiment was to test the influence of vitamin C on golden trevally, Gnathanodon speciosus. Three levels of vitamin C (100, 200 and 300 mg kg-1 diet) were added to the basal diet (use as control diet) and fed the fish (initial weight 3.52 g ± 0.11 (SEM) for 8 weeks. Growth performance and tissue protein were measured. The result showed that growth rate of fish enhanced significantly with the present of vitamin C in their diet (P< 0.05). Survival rate significantly increased in fish fed diets with 200 mg vitamin C compared to control. Protein in the flesh of fish were 18.06 to 19.53%, but protein content did not influence by vitamin C. The concentration of 200 mg vitamin C kg-1 is recommended to supplement to the feed of golden trevally for better growth and survival. In conclusion, supplemented vitamin C in diet benefits for boosting growth, survival and body composition of this species at juvenile stage.
