Możliwości zastosowania europejskiego wskaźnika ichtiologicznego (EFI+) do oceny stanu ekologicznego rzek Polski

Abstract
The European Fish Index EFI+ is a multimetric index to be applied at the continental scale. It consists of two pairs of metrics developed separately for Salmonid and Cyprinid river zones, producing two specific indices. The metrics for the Salmonid index are: density of species intolerant to oxygen depletion and to habitat degradation, while the metrics for the Cyprinid index are: number of species that prefer to spawn in running waters and density of lithophilic species. The four metrics were used in the European Intercalibration process to validate national methods of the EU members. In this paper we present the applicability and limitations of the EFI+ index in Poland. The ecoregion and watershed classification problems are examined. The need to exclude non native species considered by metrics is stressed. Possible options and some technical problems in software use are also presented.
