Abstract: The growth of 2-year-old commercial juvenile Acipenser schrenckii in pond-culture were studied.The results showed that the juveniles＇ mean total length which was 40.36cm and body weight which was 186.29g increased by 71.04% and 568.54% respectively after 60 days rearing.There was a power function relationship： W=0.0015L3.2208,R2=0.9662,between body weight and total length.The daily increasing weight,RIR,GC and GT of juveniles increased first,and reached the maxmium between 20 days and 40 days after the experiment starting,and then decreased.K ranged from 0.2834 to 0.3927.The SGR was unrelated with water temperature.The body weight and total length CV had no significantly change.
