The major carp, Labeo rohita fed with six different diets having vitamin C fortification. The
Halver's synthetic diet (H440) was supplemented with graded levels of vitamin C at 0, 250, 500, 600,
750 and 1000 mg/kg. In present investigation, Labeo rohita fed with 600 mg/kg vitamin C, gain
maximum ash (4.16%), carbohydrate (2.94%) protein (16.87%), fat (5.09 %), SGR (2.92 %), survival
rate (100 %) with least moisture content (77.10 %) as compared to control and other graded level of
vitamin C. Supplementation of vitamin C beyond 600 mg resulted in decrease in protein, fat,
carbohydrate and ash values with an increase in moisture content. The results also indicated that
Halver's synthetic diet of fish without dietary vitamin C had lower weight gain (WG) and specific
growth rate (SGR) than those fed the diets supplemented vitamin C. WG and SGR did increase with
dietary vitamin C levels increasing from 250 mg/ kg to 600 mg / kg. However, no significant increase
was observed with further increase in dietary vitamin C levels beyond 600 mg / kg.
