Fish biologists studying salmon have historically lost track of their fish, particularly when they get into the streams and creeks in the Pacific Northwest.
Scientists have developed a new way to help track the salmon heading home. They’ve installed giant antennas in over 20 rivers and streams to help track the microchipped fish. The arrays are powered with a propane generator and solar panels. Information gathered is relayed via satellite and posted in real time on a public website.
Three of the new research antennas are now in place in the Entiat River in Washington state, seven in the Wenatchee River and its tributaries in central Washington, eight in the John Day River system in northeastern Oregon, three in central Idaho’s Lemhi River basin and four in Idaho’s South Fork.
