Factors affecting detection probabilities of acoustic transmitters using passive receivers

Passive acoustic telemetry is a common tool used to study fish movements. Range tests, or determining the distance at which transmitters can be recognized by a receiver, are needed to accurately determine fish position in the environment. However, range tests are not often conducted or are only completed during a single season prior to an acoustic telemetry study commencing though seasonality may affect detection probabilities over a multi-year study’s duration. Therefore, we conducted a series
