摘 要:为分析黄河雅罗鱼(Leuciscus chuanchicus)的年龄与生长关联性,对2022年7—8月和2023年3月捕捞于黄河干流宁夏和甘肃段的271尾黄河雅罗鱼进行年龄分析,运用von Bertalanffy生长方程(VBGF)、逻辑斯谛生长方程(Logistic GF)、Gompertz生长方程(Gompertz GF)和幂指数生长方程(Power exponential GF)分别拟合黄河雅罗鱼生长,筛选出最适生长方程,并对其生长特征进行了分析。结果表明,黄河雅罗鱼样本分为1~5龄5个年龄组,其中3龄个体数量最多,占46.13%。雌雄个体间生长无显著差异,体重(W)与全长(L)的幂函数回归方程为W=0.004×L^(3.242)(R^(2)=0.991,n=271)。von Bertalanffy生长方程为黄河雅罗鱼的最适生长方程,其次是Gompertz和Logistic GF生长方程。黄河雅罗鱼全长生长方程为L_(t)=46.992×[1-e-0.274(t-^(0.333))],体重生长方程为Wt=1053.808×[1-e-0.274](t-^(0.333))^(3.242)。生长加速度曲线中的拐点年龄为4.626龄,对应的全长和体重分别为32.50 cm和318.80 g。In order to analyze the age and growth of Leuciscus chuanchicus,271 samples were caught in the sections of Gansu and Ningxia of the main stream of the Yellow River in July-August 2022 and March 2023.The von Bertalanffy Growth Equation(VBGF),Logistic GF,Gompertz growth equation(Gompertz GF)and Power exponential growth equation(Power exponential GF)were used to simulate the growth of L.chuanchicus.Model parameters were calculated by the maximum likelihood method,the most suitable model was selected by the Akaike information criterion(AIC).The results showed that the samples of L.chuanchicus were divided into five age groups,of which 3 years old group had the largest sample size,accounting for 46.13%,and there was no significant difference in growth between male and female individuals.The von Bertalanffy growth equation was the optimal growth equation for L.chuanchicus,followed by the Gompertz,Logistic GF growth equations.The VBGF growth equation for L.chuanchicus was:L_(t)=46.992×[1-e-0.274×(ti-0.333)].The age of the inflection point in the growth acceleration curve was 4.626 years,and the corresponding total length and body weight were 32.50 cm and 318.80 g respectively.
