Fucoidan, water-soluble hetero polysaccharide that contains fucose and sulfate groups which found in the cellular wall of brown algae which in this study, the effects of its various levels on growth performance, body composition and blood biochemical factors in rainbow trout, with mean weight of 74.8 ± 70 for 8 weeks were investigated. The experiments consisted of 0 (control), 0.1, 0.5, 1 and 2% of fucoidan per kg of diet in the form of five treatments, three replications were performed in 100 liters tanks. Based on the findings of this study, the highest final weight, specific growth rate and body weight gain percentage were observed in treatment 2% F, which had a significant difference with other groups (P>0.05). The highest condition factor (CF) and visceral somatic index (VSI) were observed in control, which had a significant difference with other treatments (P<0.05). There was a significant difference in amount of fat and moisture in the treatment of 0.5% fucoidan compared to the control group (P>0.05). The highest total protein and HDL were observed in 0.1% concentration of fucoidan (P>0.05) and the control group showed the highest LDL (P>0.05). Based on the results of this study, it is suggested that high dose fucoidans improve the growth performance and at low doses, they can have positive effects on blood biochemical factors.
