The purpose of this study was to investigate the effects of dietary flaxseed meal on growth performance and hematological indices of Siberian sturgeon Acipenser baerii, 32 farmed fish with average weight of 955.06 ± 53.38 g were randomly distributed in 8 tanks (500 L) in four treatment and two replicates and fed diets with different levels of flaxseed meal including 0 (control), 50 (F50), 100 (F100) and 150 (F150) g kg-1 diet for 6 months. At the end of the experiment, the results showed no significant difference in growth parameters. In hematological parameters, the number of red blood cells counts and hematocrit has significant increase in F150 compared of the control but hemoglobin, mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration have no significant difference. Result of white blood cells showed there was significant decrease in the number of white blood cells counts in control and also there is significant increase in neutrophil and lymphocyte in F150 and control respectively, but there was no significant difference in monocyte and eosinophil. The overall results revealed that flaxseed meal has no effect on growth but affected some hematological indices in the Siberian sturgeon.
