More Information
Summary:A tracking tag (104, 200) for aquatic animals (102) may detect the occurrence of a predation event. The tag may include a pH sensitive material (210a) that degrades in the environment of an animal's gut. The degradation of the pH sensitive material causes a change in a detectable characteristic of the tag, which allows the tag to detect the predation event and adjust its operation accordingly.
