This study evaluates the effects of dietary supplement Aquablend Avrin® on growth performance, nutrition, survival rate and immune factors in Aequidens rivulatus. 150 juvenile fish with initial average weight 1.50 + 0.20 g were fed by diets which contain 0.125, 0.25, 0.5, 1 g/kg supplement (treatments 1, 2, 3, 4) for two months. The results showed that 4th treatment had the best PER, FI, BWI, SGR, WBC, Albumine, Glubuline and the total serum protein (p<0.05). The FCR of 3rd and 4th treatments showed significant decrease in comparison with the first treatment (p<0.05). The least growth and nutrition performance and immunological factors were observed in the first treatment. In second and third treatments no positive effects were observed in growth and nutrition performance but there were significant immunological responses in comparison with the control (p<0.05). In conclusion, the best treatment was the 4th, so the results showed that usage of 1 g/kg Aquablend had beneficiary effects in Aequidens rivulatus.
