塔里木河流域胜利水库鲤年龄与生长研究.

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. [ABSTRACT FROM AUTHOR]
