Audio tagging devices to help study outmigrating salmonids
Scientists are inserting small pencil-eraser sized tracking devices into juvenile salmon and steelhead at the John Day dam on the Columbia River. The study hopes to improve knowledge about juvenile salmonid escapement patterns and timing. Researchers are hoping the data from the high-frequency tracking devices will help regulators institute more fish friendly dam operations.
