| 摘 要： | 2008年5-10月，在黑龙江农垦震达兴凯湖大白鱼研究所养殖基地采集兴凯湖翘嘴鲌（Culter albarnus）样本1200尾，对其年龄和生长研究结果为：体长与体重的关系式为W=0．0056L^30004（R^2=0．9952），属于等速生长型鱼类；其生长规律用Von Beaalanffy方程表示为Lt=117．54×1-e^0.093（t-0.034）]，Wt=9111．15×1-e^0.093（t-0.034）]^3.004。用Von Bertalanffy生长模型对兴凯湖翘嘴鲌的生长进行拟合，反映出其生长过程及变化规律。结果表明：兴凯湖翘嘴鲌渐进体长为117．54cm，渐进体重为9111．15g，拐点年龄在11．86龄处，拐点体重为2．70kg，拐点体长为78．36cm；与兴凯湖自然水域的翘嘴鲌生长式型不同。

| Abstract: | From May to August in 2008, 1 200 fish specimens were random collected and investigated in order to analyze the age and growth rate under the breeding bases in large white fish research institute of NOngken zhenda Xingkai lake in Heilongjiang. The experiment results show that the relationship between body length（L） and body weight（W） can be expressed in W=0.0056L^30004（R^2=0.9952） The Von Bertalantty equations of the species were as follows： Lt=117.54×1-e^0.093（t-0.034）],Wt=9111.15×1-e^0.093（t-0.034）]^3.004, the growth inflexion point was at ti=II.86 years, corresponding to L=78.36 cm and W=2.70 kg. There were differences between aquaculture ponds and wild conditions in growth patterns of Culter albarnus in Xingkai lake. |
