Projects
Title
Naturschutzgebiet Dobratal Artenschutzinitialprojekt Gewässer
Client
Provincial State Government of Lower Austria (Land NÖ), Austria
Duration
2026
Description
This project aims to restore natural freshwater ecosystems by re-establishing natural water dynamics, including the support of beaver activity, and creating structurally diverse aquatic and riparian habitats. Measures include the development of spawning and shallow-water zones, small water bodies, and structured riparian areas to enhance ecological resilience and biodiversity. The project particularly supports endangered species such as the Yellow-bellied Toad, Great Crested Newt, crayfish, and the Eurasian Beaver. In addition, long-term management and monitoring concepts will be developed to ensure sustainable ecological outcomes.
Title
Fish biodiversity assessment in Central Asia using environmental DNA (eDNA)
Duration
2025-2026
Client
Verein für Ökologie und Umweltforschung (VÖU), Kleinwasserkraft Österreich, Austria
Description
As part of a research initiative in Central Asia, eDNA samples from mountain streams and rivers are being analyzed to assess fish biodiversity and community patterns. The project supports evaluating spatio-environmental gradients and human impacts on fish populations, informing conservation and management recommendations, and developing species distribution models for the region’s freshwater ecosystems.

Title
Ökologisches Potential von Wassermanagementmaßnahmen anhand eines fischökologischen Monitorings am Marchfeldkanal als Best-Practice-Beispiel
Client
Betriebsgesellschaft Marchfeldkanal, Austria
Duration
2025-2025
Description
As a continuation of the long-term monitoring of the fish-ecological succession of the Marchfeldkanal, an artificially created tributary of the Danube, which has been regularly studied since it was flooded in 1993, a fish ecological status assessment was done. The project also involved collating recent with historical data, and analysing the fish-ecological succession. Based on this, recommendations for action were developed to preserve the ecological functions of man-made side channels like the Marchfeldkanal.
Title
Pre- and post fish ecological monitoring in connection with the underwater dredging at the Hausmening hydroelectric power station
Client
Wien Energie GmbH, Austria
Duration
2025-2025
Description
Following a major flood in 2024, dredging was required in the downstream section of the Hausmening power station to restore the original drop height. This dredging was planned and carried out as sustainable as possible in consultation with the power station operator and the fishing right owners. Limnosolve was commissioned to document the impact of the dredging work on the local fish population.
Title
DravaPulse
Client
WWF Austria
Duration
2025-2026
Description
The Project focuses on the ecological effects of hydropeaking on fish in the Drava River, Croatia. LimnoSolve was commissioned to document fish larvae stranding caused by hydropeaking, install and maintain hydrological monitoring stations, and conduct standardized field surveys of macroinvertebrates and juvenile fish in hydropeaking-affected and reference river sections to evaluate ecological impacts. The collected hydrological and ecological data provide the basis for further analyses by BOKU University.
