Scientists tag a wide range of aquatic species with uniquely coded electronic tags. These tags range in size from a chickpea to a AA battery. They are surgically implanted or externally attached to the animal and can operate for up to 10 years at a time.
Acoustic tags are transmitters that allow researchers to track the movements of animals in both freshwater and marine environments. Each tag emits a unique code that is detected and stored by an acoustic receiver when the animal travels within detection range of the unit.
Satellite tags transmit data from tagged animals directly to satellites when the animal surfaces (attached to the heads of seals or mounted on the dorsal fins of sharks) or when the tag pops off the animal on a preprogrammed date and floats to the surface. The data is then relayed to researchers in near-real time.
Passive integrated transponders (PIT) are rice grain-sized tags that operate using radio frequencies, and are primarily used for electronic telemetry on animals in freshwater environments.
Transceivers act as both a transmitter and a receiver. Large aquatic animals outfitted with this specialized combination allow researchers to track animal associations and predator-prey interactions between other tagged aquatic animals. Transceivers also collect oceanographic data from sensors on the tags animals are carrying, and, together with an...
OTN acoustic receivers are typically arranged approximately 800 metres apart on the sea floor to form an array, or a ‘listening line’, but can also be affixed to existing structures or floating buoys. When an acoustically tagged animal swims within detection range of a receiver, the acoustic signal from the tag is recorded. The receiver stores the ...
