fish food with 0, 50, 100, 150 and 200 mg/kg fish food. The result show that
supplementation of vitamin C in fish food significantly effect P< 0,05 to daily

food. Addition of vitamin C 200 mg/kg fish food yield was the best individual
absolute weight growth 15,34 g, absolute lenght growth 7,13 cm daily growth rate
3,14%, survival rate 88,89% and efficiency food 62,9%.
