Abstract

The aim of this study was to evaluate the supplementation of vitamin C in the diet on the development and survival of catfish larvae Rhamdia voulezi. 375 larvae were distributed in a completely randomized design in aquariums 30L of volume, density of 0.5 larvae per liter. The diets were formulated to make isonitrogenous, isoenergetic, isoaminoacid and isofibrosas, and supplemented with 600 (control), 850, 1100, 1600 and 2600 mg vitamin C per kg feed. The larvae were fed to apparent satiation for a period of 31 days, four times a day (8h, 11h, 14h and 17h). The water temperature was measured daily, while the physical-chemical parameters (dissolved oxygen, pH and conductivity) were measured weekly. Not observed significant differences in performance of larvae in relation to the final weight, final length, condition factor, specific growth rate and survival. We conclude that the performance and survival of catfish larvae Rhamdia voulezi are not influenced by supplementation at levels above 600 mg vitamin C per kilogram of diet.
