| 摘 要： | 2010年9～11月,对红枫湖鲢、鳙进行调查、取样分析。结果显示,红枫湖的鲢、鳙均由1～4龄组成,其中以2龄为主。鲢、鳙体长与龄径的线性函数分别为:L鲢=13.28×R+6.54、L鳙=13.94×R+6.95;鲢、鳙体长与体重拟合的幂函数公式分别为:W鲢=0.0275×L2.885、W鳙=0.0442×L2.695;鲢的体长、体重Von Bertalanffy生长方程为:Lt=80.601-e-0.1317(t+0.6899)]、Wt=8703.241-e-0.1317(t+0.6899)]2.885,鳙的体长、体重Von Bertalanffy生长方程为:Lt=96.601-e-0.1317(t+0.40784)]、Wt=9884.071-e-0.1317(t+0.40784)]2.693。

| Abstract: | The silver carp and bighead carp of Hongfeng lake in the Guiyang city was used to survey in September to December 2010.The results indicated the age of silver carp and bighead carp was both from 1 to 4,which largely composed of age groups 2.The relationship between the body length and scale radius could be expressed by the equation L鲢=13.28×R+6.54,L鳙=13.94×R+6.95.The relationship between body weight and body length can be expressed as W鲢=0.0275×L2.885,W鳙=0.0442×L2.695;The growth of body length and body weight of silver carp can be described by the Von Bertalanffy growth equation Lt=80.601-e-0.1317(t+0.6899)],Wt=8703.241-e-0.1317(t+0.6899)]2.8853,The growth of body length and body weight of bighead carp can be described by the Von Bertalanffy growth equation Lt=96.601-e-0.1317(t+0.40784)],Wt=9884.071-e-0.1317(t+0.40784)]2.695. |
