Abstract Vitamin C, along with all other vitamins, is necessary for aquatic organisms because it prevents disease, promotes growth and health, leading to improve of the biological material derived from aquaculture. Since some fish species can not synthesize vitamin C in their organism, or they do it insufficient, this vitamin is embedded into feed. However, the optimal concentrations of vitamin C that must be embedded into fish feed, are not known for all fish species. Therefore, this paper aims to assess the growth performance of juvenile sturgeons fed with four concentration of vitamin C, embedded into feed (0, 200, 400, 800 mg / kg feed). Thus, between specific growth rate (SGR) and the concentration of vitamin C embedded into feed is an inversely proportional relationship. The lowest values ​​for SGR were recorded at control variant and at the variant fed with 800mg / kg feed. Feed conversion rate (FCR) has a trend towards SGR, that makes us conclude that in case of juvenile sturgeons (155g/ex), a lower concentration of vitamin C leads to better growth.
