abstract = {Problem statement: In an effort to increase growth, improve feed utilization, reduce stress and prevent certain diseases, a 14 week feeding trial was conducted to determine the effects of different levels of dietary vitamin C (ascorbic acid) on growth, feed utilization and hematological changes in Clarias gariepinus fingerlings. Approach: Diets were formulated to contain 0, 50, 100, 150, 500, 1000 and 1500 mg L-ascorbic acid kg-1 of feed contributing 0, 0.05, 0.10, 0.15, 0.5, 1.0 and 1.5% to the formulated diets respectively. Fish of mean weight 10.12±0.7 g were fed on experimental diets in triplicate groups. Weight gain of fish fed diet with 0% of vitamin C were significantly (p0.05) affected by vitamin C supplemented diets. Fish fed the vitamin C-free diet begin to show deficiency signs such as erratic swimming, flashing, skin darkening and reduced growth at 12 weeks of feeding trial. Conclusion: This study indicated that 50 mg kg-1 of ascorbic acid is sufficient to prevent C. gariepinus fingerlings from developing clinical symptoms relating to vitamin C deficiency. A mega dose of 1500 mg kg-1 of ascorbic acid gave maximum growth performance and feed utilization efficiency.},
