新疆3种雅罗鱼生长模型的比较研究

The Growth Models of Three Kind of leuciscusin from Xinjiang

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。

Specialized von Bertalanffy growth formula, generalized yon Bertalanffy growth formula, Logistic growth formula, Gompertz growth formula, Brody growth formula were used for fitting the body length and weight growth of Leuciscus leuciscus baicalensis Dybowsky, Leuciscus idus Linnaeus and Leuciscus merzbacheri Zugmayer. The residual sum of squares of body length growth on Leuciscus leuciscus baicalensis Dybowsky was 0.012, 1.1×10^-7, 0.0001, 0.002 and 0.0002, respectively and its residual sum of squares of body weight growth was 0.34, 8.4×10^-5, 0.64, 0.68 and 130.9, respectively. The residual sum of squares of body length growth on Leuciscus idus Linnaeus was 310.2, 299.9, 544.9, 214.4 and 370.90, respectively and its residual sum of squares of body weight growth was 135698,18797,49660,125730,70046, respectively. The residual sum of squares of body length growth on Leuciseus merzbacheri Zugmayer was 4.5, 3.6, 0.5, 3.3 and 29.0, respectively and its residual sum of squares of body weight growth was 7.2, 5.4, 827, 69 and 329, respectively. Results showed that generalized VBGF was the most precise model to fit the body weight growth of three kind of fishes. Some measures arc suggested for the effective protection and the rational exploitation of three Kind of leuciscusin.
