In this study, the effects of adding different levels of ascorbic acid in diet of Barbus grypus on some growth parameters were investigated. For this purpose, 300 fish with average weight of 25.4±3.12 were randomly divided into 5 treatments, 3 replicate for each treatment. Fish were fed with following level of vitamin C in each treatment: 0, 200, 400, 800, 1600 mg/kg diet for 60 days. Biometric measurements were performed on fish at beginning, in the middle and at the end of experiment and following growth parameters: SGR, percent weight gain, feed conservation, feed efficiency, protein efficiency ratio, condition factor, increasing the length and final weight were compared between treatments. According to the results, a significant increased was observed in all growth parameters in fish that fed with higher than 400mg/kg vitamin C in comparison with control treatment.
