Abstract The dietary vitamin C (VC) requirement of red swamp crayfish (Procambarus clarkii) has not been determined. The aim of this study was to investigate the effects of dietary VC level on growth performance, body composition, nonspecific immunity, and antioxidant capacity of red swamp crayfish and to determine its VC requirement. Six experimental diets (control, VC3, VC6, VC9, VC12 and VC15) with different levels of VC (0.00, 60.13, 126.93, 192.06, 250.12 and 321.38 mg/kg diet, respectively) were fed to juvenile crayfish (average weight: 7.00 ± 0.01 g) for 70 d. At the end of the growth trial, the highest final body weight, specific growth rate (SGR), and muscle rate all occurred in the VC12 group (P
