Your Facility is Safe with DOLPINGER

➡️ Predator Attacks and Acoustic Protection Systems in Aquaculture:

Aquaculture (fish farms) is one of the most critical sectors for converting our marine and inland water resources into economic value. However, one of the greatest risk factors faced by facilities producing in offshore cages is attacks by predators, namely marine mammals (dolphins and seals). The dense fish population inside the cages acts as a major attraction for predators outside.
Dolphins and seals cause tears in the cage nets by colliding with them or biting through them. This situation leads to two major disasters: tonnes of valuable fish escaping into the sea and severe damage to the cage structure. For aquaculture facilities, this can result in financial losses amounting to millions of lira in a single night.
- An Invisible Protective Shield
Around the Cages Installing a double layer of physical netting around the cages to prevent predator attacks is not only costly but can also block the current, causing the fish inside to become deprived of oxygen. At this point, the most effective and scientifically sound solution is to install acoustic protection systems around the cages.Acoustic systems positioned at strategic angles underwater prevent predators from approaching the cage nets. The high-powered sound waves they emit cause dolphins and seals to perceive the area as a high-risk zone, thereby driving them away.

➡️ Your facility is safe with DOLPINGER:

Designed with the deep-water and challenging current conditions of fish farms in mind, the DOLPINGER Li-10, with its 3 MPa (30 bar) pressure resistance and corrosion-resistant epoxy housing, is your greatest ally in cage protection.
✅ Wide Protection Area: Depending on the density of the seawater, it completely shields an area with a diameter of hundreds of metres against predator attacks.
✅ Preservation of Net Quality: As it provides protection using only sound waves without the need for physical intervention, it extends the lifespan of cage nets and does not impede water circulation.
✅ Guarantee of Locally Manufactured Products: It protects your facility 365 days a year without interruption, eliminating the delays in parts supply and servicing experienced with imported equivalents.
