Different tags means different data are being collected. We’ll be discussing telemetry tags at length in this post, which help scientists discover what animals are doing, where they go, and what their environments are like when away from prying eyes. These tags come in a variety of shapes and sizes. Whether the tag is attached inside or outside, and how it is attached depends on the animal, the tag type, and what the researcher is studying.
Telemetry tags collect information. Tags that store information are called archival tags; tags that send information are called transmitting tags or transmitters. Satellite-linked tags will transmit a signal to a satellite, and position data is then relayed back to the scientists. This sort of data includes location, depth, and temperature which in turn can answer questions about migratory patterns, seasonal feeding movements, daily habits, survival after catch and release, etc.
Data from tagging programs allows scientists to increase our biological understanding of these animals to obtain information on stock identity, movements and migration (including rates and routes), abundance, age and growth (including verification/validation of age-determination methods), mortality, and behavior.
Other types of tags have three-dimensional accelerometers, which allows scientists to study the small scale movements of animals tagged. This leads to scientists being able to study the behavior of the animals on a micro-scale. Tags can even be inserted in the stomach, measuring the pH before, during and after digestion.
Have we missed a tag and what data can be gathered from it? Let us know!
do you ever want to tag one of these animals?
