As an EFI+ project result , an example dataset is available, to see the values of the new European Fish Index as well as pressure information for the groups hydrology, morphology, connectivity and water quality and an aggregated total pressure index for 2948 sites across Europe.
For detailed information on the modelling process, index calculation and pressure index generation see
