This dataset offers the most comprehensive freshwater fish morphology database existing to date currently encompassing 9534 freshwater fish species out of the ca. 13 000 described strictly freshwater fish species, covering 73% of the documented world freshwater fish fauna. Each species is described with ten functional traits, among which body size is estimated as the maximum body length registered on Fishbase (www.fishbase.org). The remaining nine traits describe the shape and position of the external anatomical characteristics of fishes (i.e. head, eyes, mouth, pectoral and caudal fins) that affect their feeding and locomotion. These traits were computed as unit-less ratios between morphological measures on side view pictures, using one or more specimens by species.

This global database is a compilation of long-term riverine fish surveys from 46 regional and national monitoring programs and from individual academic research efforts, with which numerous basic and applied questions in ecology and global change research can be explored. The database includes 11,386 time-series of riverine fish community catch data, including 646,270 species-specific abundance records, together with metadata related to the geographical location and sampling methodology of each time-series. The database contains 11,072 unique sampling locations (stream reach), spanning 19 countries, five biogeographical realms and 402 hydrographical basins world-wide. The database includes 944 species of rayfinned fishes (Class Actinopterygii) and encompasses the period 1951–2019 and is composed of a minimum of two yearly surveys per time series (mean = 8 years) with a minimum time span of 10 years (mean = 19 years).

This database is a combination of two database initiatives focused on the Amazon and La Plata basins. Relying on the outputs of the AmazonFish project - https://www.amazon-fish.com/, we provide the most complete fish species distribution records covering the whole Amazon drainage. The database, including 2,526 validated freshwater native fish species, over 300.000 georeferenced records (database version from 02/2022), results from an extensive survey of species distribution including over 600 different sources (e.g. published articles, grey literature, online biodiversity databases and scientific collections from museums and universities worldwide) and field expeditions conducted during the project. The La Plata basin includes the Parana, Paraguay and Uruguay river drainages, is the second most important in South America, including five countries. As for the Amazon, and because of its size and international configuration, no initiative has yet intended to compile the distribution of the fish fauna. The database is also built on from different sources together regrouping nearly 70 museum and university collections, complemented with over 800 bibliographic references. The 100.000 occurrence records range from 1829 to 2016 for 1122 native valid species and 24 exotic species (database version from 02/2022).

This database provides complete species lists for 3119 drainage basins covering more than 80% of the Earth surface using 14953 fish species inhabiting permanently or occasionally freshwater systems. The database results from an extensive survey of native and non-native freshwater fish species distribution based on 1436 published papers, books, grey literature and web-based sources. Alone or in combination with further datasets on species biological and ecological characteristics and their evolutionary history, this database represents a highly valuable source of information for further studies on freshwater macroecology, macroevolution, biogeography and conservation.

This database is built on bibliographic information (scientific publications, books and grey literature) compiling available data related to ecological species traits of neotropical freshwater fish. These traits are mainly related to reproduction, feeding , habitat preferences and growth.

This database comprises point-scale distribution data for French Guiana, including both large rivers and small streams. This database is the result of intensive fish samples for more than 10 years, and include species inventories using various capture techniques including nets, traps and toxicans. It also includes visual observations and species detections using environmental metabarcoding. This compilation comprises the distribution of more than 250 valid native freshwater fish species recorded in more than 300 sampled localities. It represents more than 50,000 fish occurrences. Tissue samples have been collected, and DNA extracted for more than 7000 specimens. This database represents the most complete freshwater fish biodiversity database for French Guiana.

Freshwater fish extinctions by drainage basin at the global scale were compiled from multiple complementary sources. We incorporated registers of fish extinctions per river basin using information from books, unpublished reports, scientific papers, local Red Lists, national comprehensive compilations of the extinct status of native freshwater fish and data from the IUCN red list.

This global dataset is a compilation of cleaned and filtered species occurrence records obtained from different global and regional databases providing point-scale geographic distribution for native species. We removed duplicated occurrences and unknown species following the FishBase valid taxonomy and synonymies. The native geographic location of each occurrence was validated according to an updated version of Tedesco et al. (2017). The final occurrence dataset offers 1,114,220 occurrence records for 12,167 freshwater fish species (‘Actinopterygii’).
