Dolpinger Li-24 Dolphin Pinger

DOLPINGER LI-24 is a domestic acoustic deterrent technology that helps protect your nets and reduce your catch losses with a working time of up to 24 Hours.

It is a professional acoustic deterrent system developed to reduce dolphin-induced net damage and catch losses in fishing activities. Developed and produced in Turkey, this innovative technology automatically activates as soon as it comes into contact with seawater and starts to provide protection.

The device generates random acoustic signals that continuously vary between 5 kHz and 400 kHz. Thanks to the adaptive frequency algorithm, the possibility of marine mammals getting used to the sounds emitted is reduced and long-term effectiveness is targeted.

DOLPINGER Li-24 is specifically designed for Gillnets and professional fishing applications.

Key benefits

• Up to 24 Hours working time
• Developed and manufactured in Turkey

• Save Time: It offers plug-and-forget convenience thanks to its smart sensors. It does not create extra workload during operation.
• 1-year one-to-one product replacement warranty against production-related malfunctions

Operation

As soon as the device is released into sea water, it starts working automatically thanks to the smart conductive sensors in its body. It emits high-power acoustic signals at random frequencies that vary continuously from 5 kHz to 400 kHz. Marine mammals (dolphins) get used to fixed frequency sounds over time and can get close to the device. The DOLPINGER Li-24's advanced adaptive frequency algorithm continuously mixes the sound sequence. In this way, it becomes impossible for living beings to adapt or become immune to sound, ensuring long-term and definitive protection. As soon as it is removed from the water, it automatically shuts off to save energy.

Dolphins can cause serious damage to the nets and loss of prey while trying to reach the fish in the nets. DOLPINGER helps marine mammals stay away from nets, contributing to reducing net damage and maintaining more efficient fishing activities.

The effective distance of the device; The salinity of the water can vary depending on environmental factors such as temperature, clarity, current condition and ambient noise.

In the field observations, the average impact distance;

• An area of approximately 600 meters in diameter in the Aegean Sea and the Mediterranean
• An area with a diameter of approximately 250 meters in the Sea of Marmara
• An area of approximately 400 meters in diameter in the Black Sea

measured as.

Uses

DOLPINGER Li-24 can be used safely in all areas of maritime thanks to its compact structure and high compressive strength.

• Extension and Voli Nets: Easily attached to the cork or lead collar of the net, with intervals appropriate to the depth of the target species.
• Aquaculture (Fish Farms): It is hung around the cages at strategic angles to prevent predator attacks from outside.
• Gillnets: Fully adapts to current and depth conditions in bottom and paragat fishing.
