In this paper,the trials of the growth characteristics of Acipenser dabryanus Dumeril under artificial culturing conditions were conducted.By experimental data processing and analysis,the results showed that the Acipenser dabryanus Dumeril reached average body weight of 1379.32 g,average total body length of 66.05 cm and average body length of 53.55 cm after 140 days rearing from average weight of 617.27 g,the average total body length of 53.45 cm and average body length of 42.38 cm.The total body length increased by 0.09 cm on average for the Acipenser dabryanus Dumeril,the mean instantaneous growth ratio was 0.151 %,and the body weight was gained at the rate of 5.443 g per day on average and the mean instantaneous growth ratio was 0.574 %.The linear relationship of total body length and body length was TL= 1.1398SL + 4.9157,R2 = 0.9986,and the total body length-weight relationship was WWTL= 0.0002TL3.7423,R2 = 0.9977,and the body length-weight relationship was WWSL= 0.0019SL3.3821,R2 = 0.9944.The power was larger than 3,which showed that the growth of weight was faster than that of the total body length and body length of Acipenser dabryanus Dumeril,which the weight ranged the 617.27-379.32 g,and the growth was allometric.
