Ultrasonic Algae Biofouling Control for Salmon and Finfish Farms
Validated in New Zealand. Built for global deployment. Engineered for distributor-scale growth.
Hydro Synergy delivers validated ultrasonic solutions that reduce algae biofouling pressure in commercial salmon and finfish operations, stabilising water quality and strengthening fish and Prawn / Shrimp welfare without chemicals or operational downtime
Our technology is built on CSR (Critical Structural Resonance), a safe, non-cavitating ultrasonic method proven across aquaculture environments and supporting lake systems in New Zealand.
The Hidden Cost of Algae and Biofouling in Aquaculture
Commercial salmon, finfish and Shrimp / Prawns farms face recurring biological and operational challenges:

Algal
Blooms & Cyanobacteria
Elevate fouling pressure, reduce visibility, and disrupt environmental stability.

Nets & Infrastructure Fouling
Accumulated biomass increases drag, reduces water exchange, and accelerates labour-intensive cleaning cycles.

Unstable
Water
Quality
Fluctuations in pH, oxygen levels, and turbidity affect feeding behaviour, welfare, and growth consistency.

Labour, OPEX & Regulatory Load
Manual net cleaning, chemical handling, and water-quality remediation increase operational cost and introduce compliance risks.
These are not isolated issues. They are systemic pressures that directly influence harvest outcomes and long-term farm performance.
WHY COMMON METHODS FAIL TO KEEP UP
Traditional solutions such as manual cleaning, high-pressure washing, and periodic chemical treatment tend to produce short-term resets, not long-term stability

High-pressure washing often breaks fouling into finer particles, which reseed faster.

Chemical approaches introduce residue, risk, and regulatory friction.

Labour interventions increase cost exposure and divert operational resources.
This cycle leaves farms chasing symptoms rather than controlling the biological drivers.
CSR Ultrasonic Technology for Aquaculture
Validated Outcome Where It Matters Most:
Hydro Synergy’s CSR-based ultrasonic systems apply tuned acoustic fields that disrupt algae aggregation, reduce fouling pressure, and help maintain cleaner, more stable aquatic environments without cavitation or destructive forces.
Proven Performance in New Zealand Salmon Farming
In our commercial salmon deployment:
-
Significant fouling reduction observed within 45 days
-
No further net-cleaning required for months, reducing labour exposure
-
Noticeably improved water visibility
-
More stable environmental conditions supporting fish comfort
-
Operators reported increased confidence in site conditions and reduced operational burden
These outcomes form the basis of our validated aquaculture category across salmon and finfish farms.
Benefits of Ultrasonic for Salmon & Finfish Farms

Reduced Net Fouling Load
Cleaner nets for extended periods mean fewer disruptions and lower manual cleaning frequency.

Greater Operational Stability
More consistent clarity, reduced biological loading, and better environmental uniformity across cycles.

Stronger Fish Welfare Conditions
Stable, cleaner water supports healthier behaviour, predictable feeding, and more uniform growth.

Lower OPEX
Exposure
Minimised cleaning cycles, reduced chemical dependencies, and smoother operations improve labour efficiency and resource allocation.

Reliable, Non-Disruptive Technology
CSR ultrasound is non-cavitating, fish-safe, and compatible with existing farm infrastructure.
