摘　　要：2018年8月至2020年10月,在鸭绿江支流、太子河与碧流河采集鸭绿沙塘鳢(Odontobutis yaluens)共472尾,成功鉴定年龄并称取457个耳石样本。年龄鉴定结果显示:鸭绿沙塘鳢种群年龄结构简单,最小为1龄,最大为4龄,2~3龄居多。通过回归拟合耳石质量与体长、年龄之间的关系,得到鸭绿沙塘鳢耳石质量与年龄之间的函数关系式,据此可利用耳石质量推断鸭绿沙塘鳢年龄。From August 2018 to October 2020,a total of 472 Odontobutis yaluens were collected in the Yalu River tributary,the Taizi River and the Biliu River,and the age was successfully identified and 457 otolith samples were weighed.The results of age identification showed that the population age structure of Odontobutis yaluens was simple,the minimum was 1 year old,the maximum was 4 years old,and the majority was 2-3 years old.By regression fitting the relationship between otolith mass and body length,age,the functional relationship between otolith mass and age of Odontobutis yaluens was obtained,which can be used to infer the age of Odontobutis yaluens.
