Rutilus frisii kutum fingerlings (n=480) with initial body weight 2.32±0.09 g and initial body length 6.04±0.12 g were fed diets that contained crude protein 43%; gross energy 4362 kcal/kg DM; Crude fat 11% including graded levels of soybean meal and corn gluten meal. A growth trial was conducted over 8 weeks. At the end of the growth trial, the body composition analysis were measured. Replacement of fish meal with soybean meal and corn gluten (9 to 15% replacement) did not significantly (P>0.05) affect on growth performance. Proximate composition was affected (P<0.05) by dietary treatments. This study showed that soybean meal and corn gluten meal have potential to replace substantial levels of fish meal in diets (15%) for omnivorous fish without compromising performance.
