Two experiments were conducted in this study to evaluate the use of sesame by-product in diet for common carp. In the first experiment, the digestibility of sesame by-product was determined using in vivo method on common carp of approximately size 250 g/fish. The chemical compositions of sesame byproduct were 17.2 percent for protein and 32.1 percent for lipid. Dry matter and protein digestibility of sesame byproduct for common carp were relatively high, reaching values of 92.8 percent and 81.4 percent respectively. Digestibility of minerals in sesame by-product for carp was high, reaching 65.6 percent. The second experiment on the impact of different incorporation level of sesame to growth performance was realized on carp of 50 g/fish with 3 diets in which 18 percent, 24 percent and 30 percent sesame were incorporated. Growth rate, voluntary feed intake and feed conversion ratio of carp using 30 percent sesame diet were lower than 18 percent and 24 percent sesame diets, but no difference when compared fish fed 18 percent sesame and 24 percent sesame diet. The sesame by-product incorporation level of 24 percent was recommanded in diet for common carp. Fish fed 24 percent sesame diet had specific growth rate SGR of 1.686 percent/day and feed conversion ratio FCR of 1.97.
