Abstract: The experiment was conducted to study the deficiency of vitamin C in juvenile jian carp(Cyprinus carpio Var. Jian). In the trial, 192 juvenile jian carps [initial weight of(11.18±0.57)g] were randomly allocated to 2 groups, fed on the semi-purified diet containing vitamin C 0mg/kg or 60 mg/kg respectively for 133 days. The results indicate:the deficiency of vitamin C in juvenile jian carp, the heart weight, spleen weight, hepatopancreas weight, gonad weight, metanephros weight, gonad weight/body weight decrease significantly(P<0.01), heart weight/body weight, metanephros weight/body weight increase significantly(P<0.01), but the hepatopancreas weight/body weight, spleen weight/body weight are not of significant differences in two groups(P>0.05); skin and fins color turning darker, hemorrhages and erosion of fins, spinal deformities and scoliosis.
