摘要: 【目的】鉴定黄河鮈的年龄,分析其生长特性,丰富黄河中上游黄河鮈的生物学研究资料。【方法】在宁夏回族自治区、甘肃省境内共7个站点采捕黄河鮈,以耳石作为年龄鉴定材料,选择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)4种模型分别模拟黄河鮈的体长生长,采用极大似然法估算模型参数,通过计算各模型的AIC值评估模型的拟合效果,确定黄河鮈的最适生长模型。【结果】共采集到黄河鮈样本550尾,分为5个年龄组,即1~5龄,其中2龄组数量最多,共351尾;体长为2.60~17.41 cm;体重为0.18~99.39 g。4种模型对黄河鮈的拟合结果为,Gompertz 生长模型的AIC值最小(4.99),拟合效果最好;其次为Logistic GF(14.58)和VBGF生长模型(16.29);幂指数生长模型AIC值最大(82.42),拟合效果最差。黄河鮈生长模型的Gompertz GF为Lt=18.81×exp{-exp[-0.66×(ti-1.73)]}。【结论】Gompertz GF为黄河中上游黄河鮈的最适生长模型。

Abstract: 【Objective】Identify the age of Gobio huanghensis,analyze its growth characteristics,to enrich the biological research data of Gobio huanghensis in the middle and upper reaches of the Yellow River.【Methods】Gobio huanghensis samples were collected in 7 stations located in the Ningxia Hui Autonomous Region and Gansu Province. Otoliths were used as age identification materials. Four models,Von Bertalanffy growth formula(VBGF),Logistic growth formula(Logistic GF),Gompertz growth formula(Gompertz GF),and Power exponential growth formula(Power exponential GF)were selected to simulate the body length growth of Gobio huanghensis. The model parameters were estimated using the maximum likelihood method. And the fitting effects of the models were evaluated by calculating the AIC values to determine the optimal growth model for Gobio huanghensis.【Results】A total of 550 Gobio huanghensis samples were collected,and divided into 5 age groups of 1 to 5 years of age. Among them the 2-year age group had the highest number of 351 samples. Body length ranged from 2.60 to 17.41 cm. Body weight ranged from 0.18 to 99.39 g. For the Gobio huanghensis simulating results of the 4 models,Gomportz GF growth model had the lowest AIC value(4.99)and the best simulating effect,followed by Logistic GF(14.58),and VBGF(16.29)growth model,while Power exponential GF growth model had the highest AIC value(82.42)and the worst simulating effect. The Gobio huanghensis Gomportz GF growth model was described as:Lt=18.81×exp{-exp[-0.66×(ti-1.73)]}.【Conclusion】Gompertz GF growth model was the most suitable growth model for Gobio huanghensis in the middle and upper reaches of the Yellow River.
