Sensor Fish
The Sensor Fish is a device that reveals what juvenile salmon experience as they pass through the turbulent waters of hydroelectric dams on their way to the ocean.
The roughly fish-sized package contains accelerometers, pressure gauges and other instruments. The devices are deployed in turbines, spillways and sluiceways to measure changes in pressure and linear acceleration that fish experience during passage.
Before development of the Sensor Fish, biologists and dam operators relied upon physical and computational fluid dynamic models to characterize spillway and turbine passage environments.
