The global Ultrasonic Fish Deterrent Transducer market size is predicted to grow from US$ 83.15 million in 2025 to US$ 135 million in 2032; it is expected to grow at a CAGR of 7.2% from 2026 to 2032.

In 2025, the global annual production capacity of ultrasonic fish deterrent transducers was approximately 37,800 units, while actual production reached about 26,562 units. The global average market price was approximately US$3,200 per unit, and the gross profit margin of major manufacturers ranged from 38% to 58%. An ultrasonic fish deterrent transducer is a specialized acoustic device that converts electrical signals into high-frequency ultrasonic waves to repel or guide fish away from protected zones. By emitting species-sensitive ultrasonic frequencies, these transducers influence fish behavior without causing physical harm, making them widely used in hydropower intake protection, water diversion projects, aquaculture facilities, and ecological conservation systems.

Upstream of the ultrasonic fish deterrent transducer industry includes piezoelectric ceramics and single-crystal materials, rare-earth elements, corrosion-resistant metal housings, waterproof encapsulation compounds, power electronics, and marine-grade cables. Midstream manufacturers are responsible for acoustic structure design, ultrasonic frequency tuning, encapsulation, calibration, and environmental reliability testing, with production concentrated mainly in China, Japan, and parts of Europe. Downstream applications include hydropower stations, irrigation and water diversion facilities, aquaculture protection systems, marine engineering projects, and ecological restoration initiatives. End users focus on ultrasonic output efficiency, frequency stability across water conditions, long-term underwater durability, energy consumption, and compliance with environmental protection standards.

The ultrasonic fish deterrent transducer market is driven by increasing ecological protection requirements and stricter regulations governing water infrastructure and hydropower projects. Compared with low-frequency acoustic deterrents, ultrasonic systems offer higher directionality and species-specific effectiveness, making them attractive for sensitive environments. Demand is growing steadily in hydropower retrofitting, aquaculture protection, and environmentally compliant water management projects. Technological development focuses on adaptive frequency modulation, intelligent control integration, and extended service life in harsh underwater conditions. Overall, the market shows moderate but stable growth, supported by environmental policy incentives and expanding water resource management investments.
