Length-weight measurements of grayling Thymallus thymallus from Northern European Russia

This dataset provides raw data on standard length (SL) and total weight (TW) of European grayling collected in five river basins of Northern European Russia. The data are useful for the calculation of the length-weight relationships (LWRs).本数据集提供了采自俄罗斯北欧地区五个流域的欧洲茴鱼的标准体长（SL）与总重量（TW）原始数据。该数据集可用于体长-体重关系（LWRs）的计算。
