Acoustic telemetry network

The Common Angelshark or Monkfish (Squatina squatina)

Acoustic telemetry network

ANGELSHARK TELEMETRY: A project from ElasmoCan that studies the behavior of angelsharks in the Canary Islands, using an acoustic telemetry network.

 

A marine acoustic telemetry network was implemented in the Canary Islands under the project “Monitoring network for the angelshark Squatina squatina in the SAC Costa de Sardina del Norte: creating knowledge for its conservation”. This scientific initiative was developed with the support from the Biodiversity Foundation of the Ministry for Ecologic Transition and Loro Parque Fundación.

The network consists of an array of anchored underwater microphones (hydrophones), registering the signals emitted from transmitters that are carried by the angelsharks. The analysis of this data tells when and where an individual was present in the study area, revealing its movement and residency patterns, and habitat use.

Understanding the significance of an area in a species’ life cycle and the objective it can achieve in its conservation involves, in between others, a continuous monitoring of its population. In this context, the network can also reveal the behavior with a detail unachieved so far in angelsharks.
