Pacific Northwest National Laboratory - PNNL
Salmon Sensors: Nodes
To understand the behavior and fate of juvenile salmon (and funded by the U.S. Army Corps of Engineers), researchers from Pacific Northwest National Laboratory and the National Marine Fisheries Service developed a sophisticated yet simple underwater acoustic fish tracking system. The system consists of autonomous receivers, anchored to the bottom of the river, and microtransmitters on the fish. Flat round anchors are attached to the long yellow receivers or nodes to keep them in place on the turbulent river bottom.
