摘　　要：2012年9月~2014年5月,在地下涌泉(7.0~18.0℃)流水池塘中养殖细鳞鱼Brachymystax lenok,研究1龄幼鱼的生长特性。结果表明:16日龄细鳞鱼经352d培育后,体长从(2.25±0.13)cm增至(18.59±1.62)cm,体质量从(0.093±0.027)g增至(116.803±33.263)g;体质量(W)与体长(L)呈幂函数关系:W=0.0084L^(3.2467)(R^2=0.9919),b值近似于3,属于生长匀速型;体长(L)与日龄(d)表现为线性相关:L=0.0491d+1.1458(R^2=0.9931);体质量(W)与日龄(d)表现为指数相关:W=0.1731e^(0.0199d)(R^2=0.9401)。The growth traits were studied in one-year-old lenok Brachymystax lenok cultured in a flowing tank from September 2012 to May 2014. In 352 days culture, Brachyrnystax lenok with initial body weight of （0.093±0.027 ） g and initial body length of （2.25± 0.13 ） cm had body weight of （ 116.803± 33.263 ） g and body length of （ 18.59± 1.62） cm. The linear relationship was found between body weight （ W ） and body length （L） and was expressed as IV=0.0084L3.467 （R2=0.9919 ）, with power of near 3, indicating allometric growth. The linear relationship between body length （L） and culture time （d） was described as L=0.0491d＋l.1458 （R2=-0.9931）, and the linear relationship between body weight （ W ） and culture time （d） was expressed as W=0.1731 e^0.0199d（R2= 0.9401 ）.
