| 摘 要： | 【目的】研究塔里木河流域开都河长身高原鳅的年龄与生长的关系。【方法】2017～2019年通过对塔里木河流域开都河长身高原鳅的采样观察,运用经典生物学测量方法鉴定年龄,分析其生长性状。【结果】开都河长身高原鳅,年龄均值为3.06±0.11+,年龄结构不符合正态分布,优势年龄个体2+;体长和体重相关方程为:W=0.013 3L2.809 4(R2=0.745 9);体长和肠长的关系式为: LI=0.730 L -2.74(R2=0.981 8);长身高原鳅渐进体长L∞=23.75 cm,生产系数k=0.64,W∞=97.42 g,t 0 = - 0.70,ti=9.14+ ;种群总体(n=139)体长和体重生长方程为:Lt = 23.75 (1-e-0.64 (t + 0.7)) 和Wt= 97.42 (1-e-0.64 (t + 0.7))2.809 4。种群总体成熟系数和丰满度:GSI＝27.20±1.80和K＝0.88±0.26。【结论】塔里木河流域开都河长身高原鳅属于异速生长,适应性较强,生长性状不稳定,在种群动态和渔业生态平衡,起到了一定的作用。

| Abstract: | 【Objective】 To research the age and growth of Triplophysa tenuis in Kaidu River, Tarim River Basin. 【Method】 From 2017 to 2019, by sampling and observing Triplophysa tenuis in Kaidu River, Tarim River Basin, the age was identified and its growth traits were analyzed by classical biological measurement method.【Result】 The average ago of Triplophysa tenuis was 3.06±0.11+, which did not meet the normal distribution. The superior individual's age was 2+; Length and weight relationships: W=0.013 3 L2.809 4(R2=0.745 9);Length and intestinal length relationship: LI =0.730 L-2.74(R2=0.981 8). Progressive length L∞=23.75 cm,the coefficient of growth k=0.64,W∞=97.42 g,t0 = - 0.70,ti=9.14+; The population (n=139) of progressive length and weight growth relationship: Lt = 23.75 (1-e-0.64 (t + 0.7)) , Wt = 97.42 (1-e-0.64 (t + 0.7))2.809 4. The population of GSI and fullness: GSI=27.20±1.80, K=0.88±0.2.【Conclusion】 Triplophysa tenuis in Kaidu River belongs to heterogenic growth with strong adaptability, but its growth traits are instable. It plays a certain role in the population dynamics and the fishery ecological balance. |
