Opis (eng)

The Danube River is obstructed by 83 continuity interruptions, out of which 65 dams are used for hydropower (ICPDR 2022a). The Iron Gate 1 and 2 dams remain significant river continuity interruption on the main stem of the Danube River, representing impenetrable obstacles for migratory fish species. The absence of fish passage at these dams has resulted in loss of genetic diversity, non-accessibility of habitats and diminishing populations. Thus, restoration of fish passage at the Iron Gate Dams has been classified as being of “utmost priority” in the Danube River Basin Management Plan. The European Commission established the “Pilot Project: Making the Iron Gates Dams passable for Danube Sturgeon” to conduct a feasibility study analysing the options to establish fish migration at the Iron Gates. Knowledge about fish behaviour and movements in the vicinity of these river structures is required to build effective up-and downstream fish passage facilities to allow the migration of fish species. To gain insight in the approach routes and aggregation areas, a refined approach to acoustic telemetry in combination with the hydraulic modelling is employed to support migration facilitation. This paper presents the initial results obtained within the Pilot Project.
