摘　　要：对采自广西红水河都安红渡镇河段的8个批次共289尾巴马繐唇鲃样本进行了生物学测定分析。结果表明：巴马繐唇鲃渔获物以1～2龄鱼为主,捕捞群体呈低龄化;体长（L）与鳞径（R）呈线性关系：L=1.782 4＋67.67R;体长与体重的关系式为W=0.033 4L^2.830 2,其生长规律用von Bertalanffy方程表示为Lt=16.477 7[1-e^（-0.219 0（t＋1.177 2））]和Wt=92.696 3[1-e^（-0.219 0（t＋1.177 2））]2.830 2;生长拐点年龄为3.57龄,此时的体长和体重分别为10.65 cm和25.04 g。生长速度和加速度曲线能反映其生长规律。建议实施巴马繐唇鲃资源保护,以维持其渔业可持续发展。Eight different timing groups, 289 Crossocheilus bamaensis samples from Hongdu Town section of Red River（Guangxi Province） were studied and the results showed that the catch population was mainly composed by young fishes which the age ranged from 1 to 2 years old. The body length（ L ） of Crossocheilus bamaensis was linearly related to scale radius （R） as L length（L） and weight（W） was W = 0. 033 4L^2.8302 = 1. 782 4 ＋ 67.67R. The relationship between body The growth pattern can be described by yon Bertalanffy equation as Lt = 16. 467 711 - e^（-0.2190（t＋1.1772））] and Wt = 92. 696 311 - e^（-0.2190（t ＋1.1772））]2.8302. The age of growth turning point was 3.57 years; the corresponding body length and body weight were 10.65 cm and 25.04 g, respectively. Curves of growth rate and accelerated growth rate can also reflect the growth pattern. C. bamaensis resource protection was suggested for its sustainable utilization.
