Freshwater Information Platform


Welcome to the database. Here you can find autecological characteristics, ecological preferences and biological traits as well as distribution patterns of more than 20,000 European freshwater organisms belonging to fish, macro-invertebrates, macrophytes, diatoms and phytoplankton.

The ecology data feature distributional parameters (e.g. ecoregional distribution or endemism, etc.), regional parameters (e.g. stream zonation or altitudinal preference, etc.), habitat parameters (e.g. temperature or substrate preference, etc.) or life related parameters (e.g. feeding type or life duration, etc.) and others. All ecological parameters can be individually combined and queried.

Query your preferred organism group. Query more than one ecological parameter. Define special interests and features.


link to quick search link to taxa entry tool link to taxa entry tool
Find your freshwater organism and its ecological preferences (» Quick Search).
Create your standardised taxalist for each of the organism groups and enter data for up to 230 samples (» TET - Taxa Entry Tool).
Upload your taxalist, validate it and export your taxa including selected ecological parameters (» TVT - Taxa Validation Tool).


25th of October 2016: Version 7.0 launched online!

We are happy to announce that version 7.0 went online. This new version includes several minor changes in the background to ensure user convenience.
The main innovation is the inclusion of trait information according to the work of Henri Tachet and colleagues (Tachet H., Bournaud M., Richoux P. & Usseglio-Polatera P. (2010): Invertébrés d'eau douce - systématique, biologie, écologie. CNRS Editions, Paris, 600 p.), resulting in Europe's most comprehensive trait collection for macro-invertebrates. We are grateful to Henri Tachet for giving permission to make these data available online and to Philippe Usseglio-Polatera for providing the data and the brief explanations for each of the traits!

Login and contact

The data presented on this website result from various EU-funded projects. We encourage a broad use of the data for purposes in science and water management. Before accessing the majority of the data, however, we kindly ask you to register, you will then get a username and a password. This procedure will ensure that we can notify you of major updates of the database. Please go to » Registration for your personal login.

The database is a "living document" and therefore permanently under improvement.
