摘　　要：为了更好地保护和开发利用塔里木河流域叶尔羌高原鳅资源,基于2019-2022年在塔里木河支流车尔臣河采集到的348尾样本,对叶尔羌高原鳅(Triplophysa yarkandensis)的年龄结构与生长特征进行研究。结果显示,采集到的样本体长分布范围为38~290 mm,体质量分布范围为0.8~271.6 g,年龄结构为1~11龄,体长体质量关系式为W=2.47×10^(-5)L^(2.8562)。von Bertalanffy生长方程雌性为:Lt=407.2572[1-e^(-0.1117(t+0.9298))],Wt=697.2606[1-^(e-0.1117(t+0.9298))]2.8756;雄性为:Lt=327.9114[1-^(e-0.1572(t+0.7154))],Wt=373.9090[1-e-0.1572(t+0.9298)]2.8353。表观生长指数分别为:ϕ♀=4.2678,ϕ♂=4.2280,拐点年龄和对应的体长、体质量雌性为:8.5龄、265.63 mm、204.04 g;雄性为:5.9龄、212.26 mm、108.94 g。研究结果表明,车尔臣河的叶尔羌高原鳅群体的生长规格和自然寿命较长,生长速度也快于其他支流。In order to better protect and exploit the resources of Triplophysa yarkandensis in the Tarim River basin,based on 348 samples collected in the Qarqan River,a tributary of the Tarim River,from 2019 to 2022,the age structure and growth characteristics of T.yarkandensis were studied.The results showed that the collected samples had a body length distribution range of 38-290 mm and a body weight distribution range of 0.8-271.6 g.The age structure was 1-11 years old,and the body length weight relation⁃ship equation was W=2.47×10-5L2.8562.The Von Bertalanffy growth equations of the female were:Lt=407.2572[1-^(e-0.1117(t+0.9298))],Wt=697.2606[1-e-0.1117(t+0.9298)]2.8756;and of the male were:Lt=327.9114[1-^(e-0.1572(t+0.7154))],Wt=373.9090[1-^(e-0.1572(t+0.9298))]2.8353.The apparent growth indexes were:ϕ♀=4.2678 andϕ♂=4.2280.The inflection point age,corresponding body length and weight for females were:8.5 years old,265.63 mm and 204.04 g;and for males were:5.9 years old,212.26 mm and 108.94 g,respec⁃tively.The results showed that the growth size and natural life of the population of T.yarkandensis in the Qarqan River was larger,and the growth rate was faster than that of other tributaries.
