摘　　要：赛里木湖湖拟鲤体长与鳞径关系为:L=0.278R-0.1582,体重与体长的关系为:W=0.01364L^3.2172应用Von·Bertal anffy生长方程拟合其生长规律,其主要生物学参数为:L∞=24.35cm,W∞=386.93g,K=0.2658,t_o-=0.7573年,拐点年龄t_1=3.45年。拐点体重(?)i=118.06g。生长指标比原产地额尔齐斯河显著减小,t=2.98>t_(0.05),P<0.05。This paper deals with the age and growth of Rutilus Rutilus Lacustris (pallas) based on the 609 speciments collected from Sai Li Mu lake. The relation between bodylength and scale radius is shown by the equation:L=0. 278R-0. 1582, The weight-Length relation can be expressed by the power function equation: W=0. 01364 L3.2172, The growth equation is Lt= 24. 35 〔1-e-0.2658(t+0.7573)〕, Wt = 396. 89 〔1-e-0.2658(t+0.7573)〕. The corrdination of inffexion point is at ti = 3. 45 Yr. Wi= 118. 06g.
