What is passive acoustic telemetry?
Passive (or autonomous) acoustic telemetry uses transmitters that ping less frequently but have a much longer battery life, and are detected by submerged stationary receivers. This strategy allows researchers to answer new questions regarding seasonal habitat preferences, coastal migrations, and survival.
How do acoustic receivers work?
Receivers are small, data-logging computers anchored near the bottom of a lake or stream or the ocean that “listen” for tagged fish. When a signal is identified, the tag's unique ID code is saved with the date and time. The data from any single receiver provide a record of each visit to that location by a tagged fish.
