The effect of replacement of dietary soybean meal with broad bean flour on rainbow trout (Oncorhynchus mykiss) with average weight of 12.5 ± 0.09 g in 4 levels (15, 30, 45 and 60%) during 7 weeks trial was examined. The results showed that substitution of soybean meal up to 30% replacement) did not have any negative impact on fish growth performance. However, significant difference in red blood cells count and hematocrit percent were found between the experimental groups and the control (P<0.05).The highest amount of red blood cells (2.03± 0.23) and hematocrit (44.3±1.52) were observed in group of 15% replacement. Also, the results of blood biochemical parameters showed that cholesterol, total protein, albumin and globulin levels in experimental groups did not significantly differ between the control and other groups. The highest level of glucose (139.04±22.2) and triglyceride (323.54±11.8) were observed in the control group, but no significantly different (P>0.05) from 15% replacement. This study showed that up to 30% fish meal replacement with broad bean flour in the diet of rainbow trout had no negative impact on the growth performance, blood factors and survival of fish.
