| 摘 要： | 实测和回归分析鄱阳湖鲌属(Culter)的翘嘴鲌(C.alburnus)、蒙古鲌(C. mongolicus)、达氏鲌(C.dabryi)和原鲌属(Culterichthys)的红鳍原鲌(C. erythropterus)体重与体维关系.结果表明,多元回归方程能全面地反映不同体维对鱼类体重的影响,体重与体侧面积体厚的回归方程较适宜.其体重(W)与体侧面积(A)及体厚(T)的幂函数关系式分别是,翘嘴鲌:W=4.05051×10-3A0.66260T1.41994;蒙古鲌:W=3.18603×10-3A0.66845 T1.44376;达氏鲌:W=1.99310×10-3A0.70982T1.47305;红鳍原鲌:W=3.58823×10-3A0.63253T1.49465.

| Abstract: | The weight and dimensions of individuals for four species, Culler albumus, C. mongolicus, C. dabryi, and Culterichthys erythropterus from Lake Poyang were measured and their regression equations were given. The multivariate formulae are better due to the fact that they reflect more comprehensively the effect of various dimensions on the weight of fish. The regression equations for body weight, side area and width are feasible. In the present study, the power equations that can give better results are W=4.05051×10-3A0.66260T1.41994(C. albumus), W=3.18603×10-3A0.66845T1.44376(C. mongolics), W=1.99310×10-3A0.70982T1.47305(C. dabryi) and W=3.58823×10-3A0.63253T1.49465(C. erythropterus). |
