The Effect of Vitamin C on the Growth performances and Survival rate of Tilapia (Oreochromis niloticus)

Abstract

The experiment was conducted in the fish farm of the collage of Agricultural technology and fish sciences, Department of fish sciences, Alneelian University, during (January to May 2017). Growth performances and survival rate of Nile tilapia were evaluated after feeding diets supplemented with vitamin C (0, 50, 100, 150 mg/kg) for 96 days. Supplementation of 150 mg/kg vitamin C to the basal diet was sufficient growth and survival rate. The average net weight gains were (11.70, 11.40, 11.50, and 12.80g), (A, B, C and D) respectively. There was no statistical difference in (FCR) Feed conversation ratio, (WG) Wight gain and other performance (p<0.05). It was observed significant difference in survival rate between the treatments. Nile tilapia Fry fed diets supplemented with 150 mg/kg vitamin C showed the optimum level of growth. The fish fed diets containing (0) mg/kg supplemental vitamin C observed low survival rate.
