Description
Abstract:
Preliminary study on sturgeon behaviour funded by the Dutch Partners for Water Programme and the ICPDR Secretariat (2014) has proven that beluga and stellate sturgeons still arrive at Iron Gate 2 dams (Danube R Km 862.8). High water current and impossibility to access Serbian reach of the Danube in the tailrace of Iron Gate 2 HEP (330 m wide) has prevented us from conducting triangulation with the mobile receiver to detect position of the sites where the beluga sturgeon male tended to congregate.
The preparatory project funded by the European Investment Bank Luxemburg (2014 - 2015) has adopted a monitoring strategy to achieve the required resolution to positioning the fish pass entrance(s). The strategy is based on four components: (i) detailed 3D bathymetry of the bottom of the river in the area of the tailrace in Romanian and Serbian territorial waters, (ii) water flow velocity profiles recorded at intervals of 100 m, (iii) combined acoustic and radio telemetry tests to achieve the required resolution needed to determine preferred positions in the river of adult sturgeons arriving downstream the dam, and (iv) integration of behavioural data with genetic analysis to distinguish phylogeny of tagged sturgeons in relation to migration seasons and known population segments.
Telemetry tests at Iron Gate 2 dams will be conducted by teams from Romania and Serbia under the guidance of a Norwegian expert. Results of this preparatory project fill be incorporated in the planning of a three year large scale study of the behaviour of sturgeons and other migratory fish at Iron Gate dams and reservoirs.
