On behalf of the Bundesanstalt für Gewässerkunde, a study is carried out at the fish-pass Malliß (River Elde), which assesses different methods for monitoring the fish migration. The surveys will be carried out over a period of 10 months using different fish migration assessment methods. The Institute of Hydrobiology and Aquatic Ecosystem Management participates in assessing migration patterns via eDNA samples. The data will be compared with those of other methods and will contribute to the development of a methodological standard for the biological function control of fish migration systems on federal waterways.

Stocking of carp has a long tradition. However due to low catch numbers its sustainability is in question. The project tackles the topic of the ability of stocked carp to reproduce at all. The second focus is on the performance of the fish when under increased/decreased predation of other fish species. The experiments will be done in two alluvial water bodies of the Danube. It will act as a basis for fisheries management in the futer in the National Park Donauauen.

The Austrian Strategy for promoting national aquaculture aims for an increase of self-sufficiency in the production of freshwater fish. Consequently, it is essential to know the limits of future aquaculture potential in Austria. Currently, there is no standardized method to assess the sustainable production limit. Therefore, aquaTool aims for the development of a suitable method to assess the aquaculture potential in Austria (especially for trout farming) under consideration of natural conditions, existing uses and legal frameworks. Within this project, a methodical procedure to assess, combine and analyse natural conditions including water availability, water quality, and space availability, potential conflicts with existing uses and/or the aim of sustainable water use (e.g. water conservation and environmental protection) will be developed, to estimate the limits of additional aquaculture production in Austria. While aquaTool aims for the development of the basic methodology, the developed procedure will then be tested and applied in the parallel project aquaNovum (Research project to assess the aquaculture project in Austria”; funded by the European Maritime and Fisheries Fund), to assess the limits of sustainable aquaculture production in Austria under consideration of different scenarios.
