The aim of the project is to produce an up-to-date Red List of Austrian fishes that takes into account the requirements and standards of the IUCN concepts. This includes a checklist of Austria's fish according to the current taxonomic classification, an endangerment analysis and classification of the fish occurring in Austria in the IUCN endangerment categories and a short species profile for each species, in which the taxonomic conditions, ecological requirements, distribution, endangerment factors and protective measures are presented and in which the endangerment classification is justified.

The Dürrenstein-Lassingtal wilderness area includes the Rothwald primeval forest, the largest remnant of primeval forest in the Alpine area. It is an IUCN-recognized protected area of category Ia + Ib and a UNESCO World Heritage Site since 2017. With its natural forests, it is an important building block in the effort to permanently safeguard rare ecosystems with their animal, plant and fungal species. The fish biocoenosis in the area has not yet been studied. As part of a comprehensive survey of the entire biocoenosis in the wilderness area, the fish populations in selected waters are being investigated and the upper distribution limits are being surveyed. Due to the exceptional biogeographical characteristics of the area and the lack of influence of fish stocking, genetic samples will also be taken for further analysis.

The fish community of the Upper Drava is being assessed through an electrofishing survey. The collected data will be analysed, compared with the results of previous surveys and interpreted. The scientific question focuses on the differences in the characteristics of the fish stocks: the parameters of population structure, abundance and biomass as well as the development of the stocks over time will be analysed. In addition, an evaluation of the fish stocks in both areas will be carried out according to the criteria of the Fish Index Austria. The research aspect consists in analysing the long-term data series against the background of abiotic and biotic developments in the Upper Drava catchment.
