Acoustic repellents « Pingers » and reflectors for netters and pelagic trawlers (LICADO project)
The pinger is an acoustic deterrent device designed to reduce the accidental capture of cetaceans (here, common dolphins). It emits a sound signal that is effective in repelling these species. The pinger is activated by contact with the water, emitting a series of ultrasounds that can be heard by the mammals’ auditory system without causing […]

Acoustic reflector
Acoustic reflectors are considered passive repellents in that they do not emit sound into the marine environment, unlike pingers. These reflectors can be ropes or other devices made of metallic materials, which are placed in the middle of the net, between the bottom and float lines, and increase the reflectivity of the net so that […]

Illumination of fishing nets
The installation of LEDs in fishing gear can improve the visibility of fishing nets and thus reduce the incidental capture of certain large marine vertebrates. These lights are automatically activated when the nets are submerged and can be of different colours and intensity depending on the species to be alerted.
