Acoustic tags have been used for years in fisheries research to study survival and behavior of fish in various aquatic environments. The described techniques, devices and systems enhance the ability of researchers to understand the effect on fish mortality by predators through an acoustic tag that includes a digestible fuse. When the implanted acoustic tag comes in contact with the digestive fluids in a predator's stomach, the fuse coating is dissolved causing the fuse to disintegrate and result in an open circuit. The open circuit in turn signals the electronics in the acoustic tag that the tagged fish has been consumed. In response, the electronics alter the tag transmit signal to indicate that predation has occurred.
An acoustic tag for implantation in a first fish, the tag comprising:
A system for studying fish predation, the system comprising:
A computer-readable storage medium including instructions that are configured, when executed by a processor in an acoustic tag for implantation in a fish and having a digestible fuse, to cause the processor to perform a method comprising:
