Vitamin groups composed of different natural compounds that can be used as an essential supplement in food dietary for fish and shrimp health, growth and reproduction. In this study fingerling common carp (Cyprinus carpio) feed on with food meals SFC containing different levels of Vitamin B₂ (7, 15 and 20 mg/kg). Also, a control group was fed with diets containing SFC without vitamin supplements. According to the biometrical parameters results and growth indices in dietary food treatments containing different levels of riboflavin vitamin shows that in biometric characteristics and percentage of weight increasing in body weight (BWI %) in different treatments have a significantly difference (P≤0/05). Maximum growth rate was found in treatment number 3 (21/52±0/55g) and minimum growth rate was observed in control treatment (18/03±0/72). According to blood hematology factors and biochemical parameters results there was a statistically significant different in MCH value in different groups in different dietary treatments shows that these treatments according to all accessed and evaluated parameters except (P≤0/05). Based on the obtained results, the optimal proportion of Vitamin B₂ in fish meal for fingerling common carp is 20mg/kg.
