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.
