采用特殊Von Bertalanffy生长方程、一般Von Bertalanffy生长方程、Logistic生长方程、Gompertz生长方程和Brody生长方程等5种生长方程,拟合了乌伦古湖贝加尔雅罗鱼、额尔齐斯河高体雅罗鱼和赛里木湖新疆雅罗鱼等3种雅罗鱼的体长生长和体重生长。这5个模型拟合贝加尔雅罗鱼的体长生长的残差平方和分别是0.012、1.1×10-7、0.0001、0.002、0.0002,拟合贝加尔雅罗鱼的体重生长的残差平方和分别是0.34、8.4×10-5、0.64、0.68、130.9,拟合高体雅罗鱼的体长生长的残差平方和分别是310.2、299.9、544.9、214.4、370.9,拟合高体雅罗鱼的体重生长的残差平方和分别是135698、18797、49660、125730、70046,拟合新疆雅罗鱼的体长生长的残差平方和分别是4.5、3.6、0.5、3.3、29.0,拟合新疆雅罗鱼的体重生长的残差平方和分别是7.2、5.4、827、69、329。结果表明:一般VBGF对3种雅罗鱼的生长具有最好的拟合效果。同时对3种雅罗鱼的保护和利用进行探讨。 Five growth equations, Von Bertalanffy growth equation, general Von Bertalanffy growth equation, Logistic growth equation, Gompertz growth equation and Brody growth equation, were used to fit the equations of growth of Baikalurus in Wulungu Lake, The body length growth and body weight growth of three kinds of Aristolochia such as the grotto and the Ariella in the Tarim Basin. The square sums of the residual growth of the body weight of the fitted Baikalurus fish were 0.012,1.1 × 10-7,0.0001,0.002,0.0002 respectively, Is 0.34,8.4 × 10-5,0.64,0.68,130.9, the residual square sums of body length growth of the fitted high body are respectively 310.2,299.9,544.9,214.4,370.9, The residual square sums of body weight growth were 135698,18797,49660,125730,70046, respectively. The residual square sums of the body length growth of the genus Xialuo were 4.5, 3.6, 0.5, 3.3, 29.0, respectively. The residual square sums of weight growth of Arroyo were 7.2,5.4,827,69,329, respectively. The results showed that VBGF had the best fitting effect on the growth of three genus Arroyo. At the same time, we discussed the protection and utilization of three species of Arroyo.
