摘要: 【目的】研究塔里木河流域上游水库鲤的年龄与生长。【方法】2015~2016年,采样观察对塔里木河流域上游水库鲤,运用传统生物学测量方法鉴定年龄,分析其生长特征。【结果】塔里木河流域上游水库的鲤,年龄均值为2.80±0.286+,年龄结构不符合正太分布,优势年龄个体1+;体长和体重相关方程为:W=0.087 2L2.506(R2=0.878);体长和肠长的关系式为: LI =3.091 3 L-50.588(R2=0.795 5);上游水库鲤的渐进体长L∞=69.57 cm,生产系数k=0.12,W∞=3 610.79 g,t0 = - 0.65,ti=1.65+ ;种群总体(n=40)体长和体重生长方程为:Lt = 69.58 (1-e-0.12 (t + 0.65)) 和Wt = 3 610.79 (1-e-0.12 (t + 0.65))2.506。种群总体成熟系数和丰满度:GSI=(12.38±1.69)和K=(72.71±1.62)。【结论】塔里木河流域上游水库鲤属于异速生长,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 Cyprinus carpio Linnaes in upstream reservoirs in Tarim River Basin. 【Method】From 2015 to 2016, through sampling observation, the age of Cyprinus Carpio Linnaes in upstream reservoirs in Tarim River Basin was determined and the growth characteristics was analyzed by traditional biological measurements. 【Result】The average age of Cyprinus carpio Linnaes in upstream reservoirs in Tarim River Basin was 2.80±0.286+, whose structure did not conform to positive distribution; The dominant individual age was 1+; The correlation equation between body length and body weight was W=0.087,2 L2.506(R2=0.878); The relationship of body length and intestinal length was LI=3.091,3 L-50.588(R2=0.795 5). The progressive length was L∞=69.57 cm, and the coefficient of growth was k=0.12, W∞=3,610.79 g, t0=-0.65, ti=1.65+; The relationship of progressive length and weight growth of the population was Lt = 69.58 (1-e-0.12 (t + 0.65) ) , Wt = 3,610.79 (1-e-0.12 (t + 0.65))2.506. The maturity coefficient and fullness of the population was GSI=(12.38±1.69), K=(2.851,8±0.210,8). 【Conclusion】Cyprinus carpio Linnaes in the upstream reservoirs, which belongs to allometric growth, has strong adaptability and unstable growth characters. It plays a certain role in population dynamics and fishery ecological balance.
