Abstract: The feeding experiments of the juveniles of Acipenser schrenckii and hybrid sturgeon (A. schrenckii♀×A. baeri♂) were conducted in cold spring water conditions.The initial average (mean±SD) body weight of sturgeon (A. schrenckii) and hybrid sturgeon were (2.51±0.57) g and (2.16±0.33) g respectively, the initial average (mean±SD) total length of the juveniles were (6.55±0.69) cm and (6.11±0.33) cm respectively, and water temperature ranged between 18~22℃.The juveniles were fed with commercial sturgeon feed (CP ≥ 48%).After 70 d of artificial cultivation, the average body weight of A. schrenckii and hybrid sturgeon were found to be (22.25±5.53) g and (26.19±6.16) g respectively, and average total length of the juveniles were found to be (13.87±0.61) cm and (14.17±0.77) cm respectively.The specific growth rate (SRG) of body weight and the SRG of total length of juveniles of hybrid sturgeon were both higher than that of A. schrenckii.The inflection point of body weight of juveniles of sturgeon (A. schrenckii) and hybrid sturgeon were 67 d and 71 d respectively, and the point of total length growth of the juveniles were 30 d and 33 d respectively, which were calculated with Bertalanffy non-linear growth model.The inflection point of total length growth appeared before the inflection point of body weight of the sturgeons;the inflection points of body weight and total length growth of the hybrid sturgeon were 4 d and 3 d later than A. schrenckii respectively, and duration of growing rate of the hybrid sturgeon juveniles was longer than that of A. schrenckii.
