PNNL researchers recently collected snake-like lamprey fish at a local dam and tagged them with PNNL's super-small tracking tag designed just for juvenile lamprey. A PNNL researcher is shown here releasing some of the tagged fish in a river so she can track their movements.

RICHLAND, Wash. - Most people think of salmon jumping upriver to spawn when they consider wild fish in the American Northwest. But another, lesser-known species - the Pacific Lamprey - is also culturally and historically important to the region. Lamprey have been on Earth at least 400 million years, which is significantly longer than salmon and even dinosaurs.
This spring, researchers tagged fish collected at a local dam with PNNL's super-small acoustic tag designed just for juvenile lamprey. Tagged fish have been released and researchers will track their movements so we can better understand how man-made structures such as dams affect them. This marks the 1st time PNNL's lamprey tag has been tested in the field.
PNNL's special lamprey tag weighs just 0.08 grams - less than a paperclip - and is designed to be injected with a syringe under a young fish's skin. It's the smallest fish tag that's part of PNNL's larger Juvenile Salmon Acoustic Telemetry System, which PNNL has been developing since 2001 to enhance fish-tracking technologies.

Pacific Northwest National Lab has developed a super-small acoustic tracking tag designed just for juvenile lamprey. In this video, PNNL researcher Alison Colotelo describes how she and her colleague Kate Deters inject young lamprey with the PNNL tag. For more information about PNNL's acoustic tags, contact PNNL researcher Daniel Deng or PNNL commercialization manager Sara Hunt.
Interdisciplinary teams at Pacific Northwest National Lab address many of America's most pressing issues in energy, the environment and national security through advances in basic and applied science. Founded in 1965, PNNL employs 4,400 staff and has an yearly budget of nearly $1 billion. It is managed by Battelle for the D.O.E.'s Office of Science. As the single biggest supporter of basic research in the physical sciences in the United States, the Office of Science is working to address some of the most pressing challenges of our time.
