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.The first marine acoustic telemetry network in the Canary Islands was created under the projectMonitoring network for the angelshark Squatina squatina in the SAC Costa de Sardina del Norte: creating knowledge for its conservation. This scientific initiative is developed with the support from the Ministry for the Ecologic Transition through the Biodiversity Foundation 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 shows when and where an individual was present in the study area, revealing more knowledge about its behavior.

Long-term monitoring

The study focusses on knowing the movement and residency patterns, and habitat use of the angelshark in the SAC Costa de Sardina del Norte from the Natura 2000 network. This novel knowledge is necessary to inform the competent authorities on their conservation strategies in this area and will also be used to raise awareness about the presence and importance of the species in the SAC.
