Abstract An automatic tracking system controlled by an RCA 1802 microprocessor was developed to locate fish in a 400 m outdoor experimental channel at the U.S. EPA Monticello Ecological Research Station. The monitoring network consisted of 12 horizontally polarized antennas spaced at 30 m intervals. The antennas were sequentially switched into a receiver, and the signal strength at each antenna was measured with the microprocessor controlling all timing, switching and measurement functions. Each fish tracked by the system was tagged with an implanted radio transmitter which had a unique frequency in the 53 MHz band. A particular fish was tracked by entering a particular radio frequency into the memory of the receiver. During May 1979, a comprehensive tracking system performance test generated 36,000 locations on 11 walleyes, 4 open noise channels and 2 primary reference transmitters. Results indicated that the tracking system located radio-transmitters to the nearest antenna with a reliability of 98.7%.
