摘要:

【目的】鉴定拟硬刺高原鳅年龄,探究其生长变化,为高原鳅属鱼类积累基础生物学资料,并为黄河中上游渔业资源保护提供参考。【方法】拟硬刺高原鳅样本采自黄河中上游青海省和甘肃省不同渔业站点,选用耳石材料鉴定其年龄,并分别采用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)4个模型模拟拟硬刺高原鳅的全长生长,采用极大似然法估算模型参数,通过计算并对比各模型的AIC值评估模型的拟合效果,确定适合拟硬刺高原鳅的生长模型。【结果】拟硬刺高原鳅的样本共分为4个年龄组,即2~5龄,其中3龄组数量最多,占54.88%;全长为6.19~13.76 cm;体重为1.58~19.12 g。4个拟硬刺高原鳅生长模型拟合结果表明,Logistic GF生长模型的AIC值最小(-86.66),拟合效果最好;其次是Gompertz GF(-86.52)和VBGF生长模型(-86.31);幂指数生长模型的AIC值最大(-82.51),拟合效果最差。拟硬刺高原鳅生长模型的 Logistic GF 方程为$ L_{t}=\frac{14.585}{\left[1+\mathrm{e}^{0.568\left(t_{i}-1.948\right)}\right]}$。【结论】Logistic GF 生长方程为黄河中上游拟硬刺高原鳅的最适生长模型。

Abstract:

【Objective】Identify the age of Triplophysa pseudoscleroptera and explore the growth changes to gather basic biological data for Triplophysa,and provide references for the protection of fishery resources in the middle and upper reaches of the Yellow River.【Methods】Triplophysa pseudoscleroptera samples were selected from different fishing stations in Qinghai Province and Gansu Province in the middle and upper reaches of the Yellow River. Otolith materials were used to identify the age. Von Bertalanffy GF(VBGF),Logistic GF,Gompertz GF and Power exponential GF were used to simulate the full-length growth of Triplophysa pseudoscleroptera. The maximum likelihood method was used to estimate the model parameters.The fitting effect of the models was evaluated by calculating and comparing the AIC value of each model to determine the growth model suitable for Triplophysa pseudoscleroptera.【Results】The Triplophysa pseudoscleroptera samples were separated into 4 age groups ranging from 2 to 5 years,with the 3-year group having the most amount,accounting for 54.88%. The full-length of the samples ranged from 6.19 to 13.76 cm,and the body weight ranged from 1.58 to 19.12 g. The fitting results of the four Triplophysa pseudoscleroptera growth models showed that the Logistic GF growth model had the lowest AIC value(-86.66)and best fitting effect,followed by Gompertz GF(-86.52)and VBGF(-86.31)growth model. Power exponential GF growth model had the highest AIC value(-82.51) and the worst fitting effect. The Triplophysa pseudoscleroptera growth model Logistic GF equation was $ L_{t}=\frac{14.585}{\left[1+\mathrm{e}^{0.568\left(t_{i}-1.948\right)}\right]}$.【Conclusion】Logistic GF was the most suitable growth model for Triplophysa pseudoscleroptera in the middle and upper reaches of the Yellow River.
