<div style="text-align: justify;">Aflatoxins are toxic chemicals that are produced by <em>Aspergillus flavus</em> and <em>Aspergillus parasiticus</em> species of fungi. Aflatoxicosis caused by consumption of aflatoxin-contaminated feeds represents one of the serious diseases in most fish species. Due to the lack of information regarding the effects of aflatoxin B<sub>1</sub> (AFB<sub>1</sub>) on farmed <em>Acipenser stellatus</em>, providing practical information for rearing of <em>A.stellatus</em> is imperative. <em>A. stellatus</em> fingerlings with the mean initial weight of 7.90<span dir="RTL">± </span> 0.12 g were kept in 50 Liter tanks with 10 fish per tank in a one way through water system with well water. Fish were adapted to the rearing conditions. The experimental diets were formulated to contain 1500, 1850, 2300, 2850 and 3500 ppb AFB<sub>1</sub> kg<sup>-1</sup> diet. Two control diets were also considered. Fish were fed each of the experimental diets in triplicate groups three times a day for 52 days. At the end of the experimental period, there were significant effects (p<0.05) on WG%, final biomass, condition factor (CF), specific growth rate (SGR) and survival rates with the increase in aflatoxin levels in diets. There were significant differences (p<0.05) in blood parameters including WBC, RBC, HB and PCV % and also liver enzymes such as AST, ALT and ALP with the increase in aflatoxin levels in diets. 50% of fingerlings perished after 52 days of feeding at the concentration of 3500 ppb AFB<sub>1</sub> kg<sup>-1</sup>. The results of this study revealed that <em>Acipenser stellatus</em> was relatively resistant to aflatoxin B<sub>1</sub>.<br>
