The EFI software tool also enables sites to be
assigned to “European Fish Types” (EFT) defined within the FAME project.

The European Fish Index (EFI):
The European Fish Index is a multimetric fish-based assessment method for the ecological status of European rivers developed during the FAME project. The principle of the European Fish index is to
(1) predict reference conditions for any newly sampled site by modelling 10 reference metrics as a function of 13 abiotic, location and sampling variables. The 10 final metrics were selected as the most suitable ones based on statistical tests of ca. 200 potential metrics. In terms of functional aspects these metrics cover
trophic structure of fish assemblages (density of insectivorous and omnivorous species),
reproductive guilds (density of phytophilic species, relative abundance of lithophilic species),
physical habitat (number of benthic and rheophilic species),
tolerance (relative number of intolerant and tolerant species) and to
migratory fish behaviour (long-distance migrators, potamodromous species).
(2) calculate observed metrics based on sampled individuals
(3) measure the deviation between observed and predicted reference metrics by using residuals
(4) transform the deviation into probabilities that the metric belongs to the reference set
(5) calculate the final index as mean of the 10 probability metrics.
