Fish Radio Tracking PGE biologists use radio transmitters to track migrating steelhead, chinook and coho salmon and assess the effectiveness of fish passage facilities. Radio transmitters are inserted non-surgically into the stomach, and biologists use radio receivers to pick up unique signals emitted from each fish. They track fish daily to learn how fast and far they travel and where they hold. Steelhead travel as far as 10 miles in a single day, while salmon move as far as five miles a day. Chinook will hold in the river for several months waiting to spawn, while coho and steelhead spawn relatively quickly. Using radio telemetry, PGE biologists have determined that salmon and steelhead migrate as far up the Clackamas as River Mile 70, about 50 miles upstream of Estacada.
