Overview

Continuous pinger tags with sensors are used to manually track fish and monitor other environmental variables such as temperature and pressure. Using continuous ultrasonic tags allows researchers to spend extended periods tracking a study subject in order to better characterize the movement patterns and behavior of an individual. The tags emit pulse bursts every three seconds on a frequency of 84 kHz. Several tracks of adult green sturgeon and juvenile steelhead trout have already been conducted in the Central Valley and more tracks are planned.
