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.
