Objectives: To conduct on site 3D bathymetry survey and ADCP velocity profiles Choose and adopt low stress inducing handling methods for tagging sturgeons To test bio-telemetry methods and equipment

6 Objectives: To conduct on site 3D bathymetry survey and ADCP velocity profiles Choose and adopt low stress inducing handling methods for tagging sturgeons To test bio-telemetry methods and equipment to achieve required resolution for locating sturgeons d/s Iron Gate II dams To choose molecular biology method to describe genetic diversity of tracked sturgeons To work out strategy for monitoring sturgeon behavior to ensure functionality of future up - and down stream fish passages

7 Materials and Methods 1. Fish handling in the nets to avoid lifting it of the water Side electro-narcosis (2013)

8 2. Electro-narcosis tube for surgical implanting of acoustic transmitters (2009)

9 Testing detection range of Vemco vs Thelma acoustic transmitters and receivers 100 Kg VR2 W TBR 700 V16 P Mega 16P

10 Results: 1. ADCP velocity profiles & 3D bathymetry

11 2. Multibeam 3D bathymetry

12 3. Testing detection range of Vemco vs. Thelma acoustic equipment Range test number 1. Signal strength (db) on TBR Thelma tag ID 3 & 4 ID ID Range test number 2: # detections of Thelma Tag ID 3 / 15 min VR2w #1 VR2w #2 TBR 31 TBR Range test number2. Signal strength (db) on TBR Code ID3 Code ID 4 Range test number 3. Signal strength (db) and number of detections on TBR # Tag 3 dbtag

13 4. Testing detection range of ATS 3 stage radio transmitters Receiver SRX_600 from Lotec Inc. Canada, covering the frequency range from 142 to 143 MHz 4 element Yagi antenna + 2 m long coax (RG58) cable 12 mm rope with the whip antennas in a horizontal position at 0.5 m up from the bottom at water depth of 11.5 m Due to extremely high radio noise signals from radio tags could not be recorded at all

16 Conclusions: 1. Electro-narcosis proved adequate for reducing stress and subsequent drop back in adult sturgeons; 2. 3D bathymetry and ADCP velocity profiles are essential tools for understanding environmental conditions d/s Iron Gate dams; 3. Novel Thelma receiver TBR 700 has the capability to record signal strength; 4. A combination of Vemco and Thelma acoustic tags and receivers will be used to achieve required resolution of sturgeon movements d/s Iron Gate dams; 5. Existing DNA samples collected during will be used as reference for understanding genetic diversity of sturgeons arriving at the dams Acknowledgements: Project funded by The European Investment Bank Luxemburg Contract # CC6451 / PO73375

17 Objectives: Thank you for your attention! -Capture and tag 10 adult sturgeons with acoustic transmitters -Track their movements using submerged automatic receivers with depth sensor Questions?
