Fish Tracking - Frequently Asked Questions
- What is "constant
depth?"
Each Microwave Telemetry Archival Pop-up Tag is equipped with an automatic release feature whereby the tag pops off and begins to transmit to Argos if it senses that it has been at a constant depth for four days. Depth variations less than twenty meters are regarded as constant depth by the tag.
This pressure release mechanism is standard on Archival tags for good reason—it indicates when a fish is dead or a tag is detached. Tags that detach and float around for months before the programmed data transmission time have a poorer reporting rate; the opportunities for the tag to be eaten, covered in growth, washed up on a beach or otherwise damaged reduce the chances of getting the archived data.
The automatic release feature may initiate pop off from a live fish if the fish being tracked remains in shallow water or within a narrow depth range for four days. Although it is possible to disable the automatic release feature, this is not something we recommend in most cases.
Contact us to discuss your project if it is possible that the fish you are tracking may remain at a constant depth for four days in the course of its normal behavior.
