摘  要:
报道了青海湖裸鲤的年龄生长特点。以鳞片上的年轮作为年龄鉴定依据。体长与鳞长之间呈直线正相关L=104.6+2.1s(r=0.934 2),体重与体长呈指数函数相关W=1.5×10~(-5) L~(2.9784),其生长规律适合Von Bertalanffy方程:Lt=885〔1-e~(-0.04(t+1.4)〕,Wt=9201.9〔1-e~(-004(t+1.4)〕~3.研究结果表明:青海湖裸鲤一生中生长无明显阶段性。

摘  要:
The age and growth of Gymnocypris przewalskii were reported. The scales are used for age dertermination. The relationshin between body length and scale length is expressed as L_e = 104.6 + 2. 1s. The lengthweight relationship is shown as W = 1.5×10~(-5)L The growth of Gymnocypris Przewalskii corres ponds to Von Bertalanffy's growth equation, the results are as follows: Lt =855[1-e~(-0.04(t+1.4))] Wt =9201.9 [1-e~(-0.04(t+1.4)]~3 There isn't siginificant period of growth in Gymnocypris przewalskii's life.
