Profish Technology is a spinoff created by the university of Liège in 2007 and specialised in monitoring fish ecology. Our activities essentially meet the needs of our customers (public administrators and power companies). The great majority of the projects study the success of fish migration, either the upstream migration through different types of bypass structures (fish ladders, fish locks, fish elevators, etc.), or the downstream migration along hydroelectric dams. To conduct our studies, we have invested in high-tech equipment enabling us to choose the most appropriate tool to approach the biological issue in the best possible way.
Within the scope of the LIFE4FISH project, our mission is to measure the success of migration of Atlantic salmon smolts and silver eels along hydroelectric dams managed by Luminus. A hydrophone array is deployed on each site to enable us to determine the routes used by fish to cross dams, turbines or locks with a sample of 150 fish per species. The tool used in this study is acoustic telemetry.
Field studies on the survival of fish passing the sites through turbines are also conducted by injecting fish into the turbines, retrieving them with a net and examining them thoroughly before and after their passage.
Once the protective systems have been installed on the different sites (repellent screens, outlets, etc.), we will be responsible for studying their effectiveness. To do so, we will implement the best available technologies (RFID, radio telemetry, tagging-recapture, etc.)..
Profish is a flexible international team based in Wallonia and with offices in France and Germany.
