JDS4_FISH_LONGITUDINAL_OCCURRENCES_RIVER_DANUBE.xlsx

Standardised fish sampling was carried out in 2019 as part of the Joint Danube Survey 4 project to assess the occurrence of fish fauna along the entire length of the Danube River, excluding the delta. The current dataset contains 22 fish families, of which 21 belong to ray-finned fish and one to lampreys. In total, the dataset is composed of 77 taxa and 77,794 individuals of fish. The dataset will be especially relevant for future taxonomic comparisons of the River Danube with other rivers and for examining spatial and temporal fluctuations in species composition throughout the Danube profile.

2019年，作为多瑙河联合考察4号（Joint Danube Survey 4）项目的组成部分，研究人员沿多瑙河全河段（不含三角洲）开展标准化鱼类采样工作，以评估该流域内鱼类区系的分布情况。本数据集涵盖22个鱼类科，其中21个隶属于辐鳍鱼类（ray-finned fish），1个隶属于七鳃鳗类（lampreys）。数据集总计包含77个分类单元与77794尾鱼类个体。该数据集将尤其适用于未来多瑙河与其他河流的鱼类区系分类学对比研究，以及解析多瑙河全河段物种组成的时空动态波动。
