Long-Range PIT Tag Detection in Willamette Basin: Techniques and Applications

This research focuses on the development of a long-range PIT tag detection system in the Willamette Basin. Conducted by Vince Tranquilli and Mark Wade, the project utilizes innovative technologies such as half-duplex read cycles and specialized antennas to improve fish tracking. With costs totaling approximately $216 for the antenna and $300 for the handheld reader, the system is designed for fish sizes over 100 mm. It records unique identification codes along with time and date, offering insights into fish movement and habitat use.
