This study investigated the effects of substitution dried pit instead of wheat flour on growth, survival, and body composition in Benni fish (Mesopotamichthys sharpeyi) for 60 days. Five experimental diets (three times) were made with the same energy and protein, with replacement 0, 20,30, 50, and 70 percent of the dried pit with wheat flour. The 450 Benni (Mesopotamichthys sharpeyi) with an average weight of 2.24 ± 0.1 gram were divided in a completely randomized design in fifteen 135-liter tanks with a density of 30 fish. Fish were fed experimental diets five times with the amount of 10 percent of body weight. The results showed that indices (growth and feeding) of fish fed by experimental diets were not significantly different (P>0.05). No significant difference was observed in the survival of fishes fed by different experimental diets (P>0.05). The body protein in fish fed 30, and 50 percent of dried pit was higher than in the other treatments (P<0.05). The highest percentage of body fat was observed in fish fed with replacement levels of 20, 30, and 70 percent was observed (P<0.05). Ash bodies of the fish fed with different experimental diets were not significantly different (P>0.05). In general, it can be suggested as a source of cheaper carbohydrates in Benni fish (Mesopotamichthys sharpeyi) without negative effects on the growth indices, feed utilization, and survival in Benni fish (Mesopotamichthys sharpeyi).
