摘　　要：2013年5月~2015年6月,在地下涌泉水(7~18℃)流水池塘中,采用全人工饲料投喂养殖哲罗鱼Hucho taimen进行生长性能研究。经2年养殖,鱼的平均体质量达508g,平均体长(L_B)达36cm,成活率57.6%;特定增长率、日增率和肥满度,随水温的升高而增加,随水温回落而下降;体长与全长(L_T)的关系式为L_T=1.0856L_B+0.5097(R^2=0.9975),体长与体质量的关系式为W=0.0139L^(2.9423)(R^2=0.9931);体质量变异系数13%~46%,体长变异系数2%~16%;肥满度0.85~1.35。Juvenile taimen Hucho taimen were reared in flowing water ponds and fed formulated feed at water temperature of 7℃-18℃ from May 2013 to June 2015. The 2 year old fish had average body weight of 508 g and average body length of 36 cm, with the survival rate of 57.6%. The special growth rate, daily weight gain and condition factor were affected by the change of water temperature, they were increased with temperature increasing and decreased with temperature decreasing. The linear relation model between body length（L_B）and total length（L_T）was described as L_T=1.0856L_B＋0.5097（R-2=0.9975）, and the curve relation model between body length and body weight of the taimen was expressed as W= 0.0139L-（2.9423）（R-2=0.9931）. The coefficient variation was changed from 13%to 46% in body weight, from 2% to 16% in body length and changed from 0.85 to 1.35 in condition factor.
