Underwater Acoustic Technologies: Working Principle and Use in Fishing
What are Underwater Acoustic Technologies?
Under the Sea It's Hard to See, Hearing Is More Effective
Humans rely heavily on their sense of sight underwater.
However, the most reliable source of information for a significant part of marine creatures is sound.
Visibility underwater; Turbidity can be severely reduced depending on plankton density, weather and amount of light.
In contrast, sound waves can propagate over much longer distances in favorable conditions.
Therefore, acoustic technologies play a critical role in maritime, scientific research, and commercial fishing.
Why Is Sound So Important Underwater?
Sound in the marine environment;
- Wayfinding,
- communication,
- prey detection,
- Hazard perception,
- analyzing the environment
It is used for many purposes such as.
Dolphins, whales, and certain fish species utilize advanced auditory systems to perceive their surroundings.
This biological fact has also inspired the development of modern underwater technologies.
How Do Sound Waves Travel in Water?
Sound is created by the travel of vibrations through a medium.
The main factors affecting the propagation of sound in seawater are:
Water Temperature
As the temperature rises, the propagation characteristics of sound can change.
Salinity
The salt content in seawater can have an impact on acoustic transmission.
Pressure and Depth
As the depth increases, the pressure rises, and this is one of the factors that affect the behavior of the sound.
Seafloor Structure
Rocky, sandy, or muddy floors can alter the reflection character of sound waves.
Where Are Acoustic Technologies Used?
Underwater acoustic systems are not only used in fishing.
Main areas of use:
- Marine research
- Oceanography
- Military systems
- Port security
- Seabed mapping
- Underwater robots (ROV/AUV)
- Fish finder sonar systems
- Commercial fishing equipment
Acoustic Pinger Technology
Acoustic pinger devices are electronic systems that generate acoustic signals at specific intervals.
The models used in commercial fishing aim to contribute to the easier perception of nets by marine mammals.
This approach;
- reducing network damage,
- supporting operational efficiency,
- Sustainable fishing practices
It is considered among the technologies that can contribute.
Dolpinger Technology's Approach
While developing Dolpinger products, not only electronic circuit design;
– waterproof performance,
- long battery life,
– low energy consumption,
- Durable body structure,
– reliable acoustic performance,
- Adaptation to sea conditions
is kept in the foreground.
These features aim to support the reliability of the product under heavy commercial usage conditions.
A Real Operation Scenario
A purse seine boat hunts in different regions during the season.
The Captain notices that web damages recur more frequently in certain areas.
Instead of just performing network repairs, the team analyzes operations data.
As a result of the evaluation:
- the network layout is reviewed,
- the maintenance plan is updated,
– the placement of acoustic pinger systems is optimized,
- Operation records begin to be kept digitally.
Within a few months, maintenance processes become more planned and equipment management improves.
Dolpinger Expert Review
Acoustic technology alone is not a guarantee of success.
Best results;
- choosing the right product,
- correct assembly,
- regular maintenance,
- Operations planning
It is obtained when applied together.
Dolpinger's development approach is based on this holistic understanding.
Conclusion
Underwater acoustic technologies are one of the most important engineering areas of modern fisheries.
When electronic systems, acoustic knowledge and field experience are evaluated together; equipment management can become more planned, and operations can become more efficient and sustainable.
Dolpinger aims to contribute to the industry by developing these technologies in accordance with the needs of professional fishermen.
