By-catch reduction device for marine mammals.
More than 15 years ago we developed, in compliance with EU and USA regulations, the so-called PINGER® acoustic device to avoid accidental capture of dolphins and other marine mammals in fishing gear, emitting acoustic pulses similar to those produced by marine mammals to echolocate prey. The purpose of these emissions is to alter the echo-image perceived by the animal, partially annulling the effectiveness of its natural sonar.
This acoustic deterrent device for dolphins and other cetaceans is developed in accordance with the published Commission Implementing Regulation (EU) 2020/967 of 3 July 2020, which specifies for this model of PINGER®that its installation in fishing nets must be carried out maintaining a maximum spacing between devices of 200 metres, with an acoustic device attached to each end of the net or combination of nets joined together.
- Acoustic deterrent device for dolphins and other cetaceans, proven effective for more than 10 years.
- Suitable for different fishing gear, complying with European and international regulations on animal protection and the environment.
- Easy handling, transport and storage.
- The long life of its batteries avoids handling by the user and extra work for boat personnel.
- Made of highly resistant and durable materials.
- Its sealing system and outer casing allows it to be effective at a depth of 500 metres, without water leaks or deterioration of the components.
- Automatic activation in the aquatic environment and system shutdown in dry environments.
- Device with electrostatic discharge protection circuit, by means of a special semiconductor element.
- Battery consumption warning by means of an LED indicator light. The low battery indicator lights up automatically when the element is removed from the water, indicating, for 30 seconds with a flashing pulse light, that the element has reached the end of its useful life and must be replaced by another one.
- This indication remains operational for more than a week, emitting light pulses each time the element is used.
