Abstract

The growth of 1-year-old juvenile Acipenser schrenckii in pond-culture was studied.The results showed that the juveniles' mean total body length which was 25.99 cm and body weight which was 53.70 g increased by 58.83% and 360.20% respectively after 60 days rearing.There was a power function relationship:W=0.000 6 L3.484,R2=0.991 6,between body weight and total body length.The daily increasing weight,RIR and SGR of juveniles increased with the water temperature decreased,and reached the maxmium until 20.0℃,and then decreased.GC ranged from 0.248 4 to 0.511 2,GT ranged from 0.049 6 to 0.102 2,K ranged from 0.289 4 to 0.372 9.The body weight and total body length CV showed an increasing trend.
