塔里木河流域胜利水库鲤年龄与生长研究

Age and Growth of Cyprinus carpio Linnaes in Shengli Reservoir in Tarim River Basin

为了探究塔里木河流域胜利水库鲤的年龄与生长。2012-2013年通过对塔里木河流域胜利水库鲤的采样观察,运用传统生物学测量方法鉴定年龄,分析其生长特征。结果表明:塔里木河流域胜利水库的鲤,年龄均值为3.88±1.254+,年龄结构不符合正太分布,优势年龄个体5+;体长和体重相关方程为:W=0.192L2.443(R2=0.9590);体长和体高的关系式为:H=0.2870 L+0.0970(R2=0.9810);体长和鳞径直线相关方程为:L=12.214R-78.810(R2=0.9320);体长和鳞径幂指数相关方程为:L=0.023R3.232(R2=0.9550);胜利水库鲤的渐进体长L∞=105.58cm,生产系数k=0.0479,W∞=16862.08 g,t0=-2.699,ti=4.208+;种群总体(n=25)体长和体重生长方程为:Lt=105.58[1-e-0.0479(t+2.699)],Wt=16862.08[1-e-0.0479(t+2.699)]2.443。种群总体丰满度:K=2.2108±0.2959。胜利水库鲤,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。

To research the age and growth of Cyprinus carpio Linnaes in Tarim River basin from Shengli reservoir,from 2012 to 2013,samplings of Cyprinus carpio Linnaes were collected by using traditional measurement methods to identify biological age and analyzed its growth characteristics. The results showed that Cyprinus carpio Linnaes,the age mean was 3. 88 ± 1. 254＋,the age was too distributed,superior individuals aged 5＋; Length and weight relationships： W = 0. 192L2. 443（ R2= 0. 9590）; Length and height relationship： H = 0. 2870 L ＋ 0.0970（ R2= 0. 9810）; Length and the radius of the scalesis relationship： L = 12. 214R- 78. 810（ R2= 0. 9320） ： Length and the radius of the scalesis relationship： L = 0. 023R3. 232（ R2= 0. 9550）. Progressive length L∞ = 105. 58 cm,the coefficient of growth k = 0. 0479,W∞ =16862. 08 g,t0=- 2. 699,ti= 4. 208＋; The population（ n = 25） of progressive length and weight growth relationship： Lt= 105. 58 [1-e- 0. 0479（ t ＋ 2. 699）],Wt= 16862. 08 [1- e- 0. 0479（ t ＋ 2. 699）]2. 443. The population of fullness： K = 2. 2108 ± 0. 2959. Cyprinus carpio Linnaes had strong adaptability. Its growth traits was instability,and it played a role in population dynamics and fisheries ecological balance.
