Why Algae Biofouling Become Operational Risks in Salmon & Finfish Farms?
In salmon and finfish operations, cyanobacteria and early-stage algae biofouling often develop before visible fouling becomes obvious.
Accelerated net fouling between cleaning cycles
Reduced water movement and localised water quality instability
Increased frequency of mechanical or chemical interventions
Higher operational cost and planning uncertainty
These challenges are typically site-specific, influenced by stocking density, seasonal conditions, water movement, and farm layout.
How Ultrasonic Works in Salmon & Finfish Farms?
Ultrasonic Application in Salmon & Finfish Operations
Hydro Synergy’s ultrasonic system emits low-power acoustic frequencies tuned to interfere with algae development and early algae biofouling processes.
Key characteristics:
Non-chemical
Non-cavitational
Continuous operation
No moving parts in the water
The system is designed to operate alongside existing farm practices, without replacing standard husbandry, monitoring, or cleaning protocols.
Deployment Configuration in Salmon/Finfish Farms
Deployment Overview:
-
Cage layout and spacing
-
Water depth and flow characteristics
-
Target control zones (e.g. nets, pen perimeter, intake zones)
Deployment is configured based on:
-
Transducers positioned to allow free movement in the water
-
Cabling routed to minimise operational interference
-
Shore-based or platform-based control units
-
Integration with existing power infrastructure where available
Typical deployment considerations:
Deployment configuration is finalised during assessment and confirmed prior to trial or commercial rollout.
(Industry-level aquaculture solutions are covered separately.)
Ultrasonic Control Scope for Salmon & Finfish Farms
Algae Pressure Indicator
Site-specific algae pressure tracked as an indicator of water column fouling
Net & Infrastructure Fouling Behaviour
Observed fouling behaviour on nets, pen perimeter, and intake infrastructure.
Water Clarity & Suspended Load
Recorded changes in water clarity and suspended load monitored over time.
Operational Interventions
Changes in cleaning or chemical intervention cycles are documented for internal review.
What Hydro Synergy CSR System Does Not Replace:
The ultrasonic system is designed to support cyanobacteria and early algae biofouling control. It does not replace:
Net cleaning operations
Biosecurity protocols
Farm-specific lice management strategies
Regulatory monitoring requirements
This ensures operational clarity and maintains alignment with farm compliance obligations.
Technical Benefits of Hydro Synergy Ultrasonic in Salmon & Finfish Farms
Continuous Algae Pressure Management
The system operates continuously, targeting algae development processes rather than reacting after blooms or fouling are established.
Support for Reduced Chemical Reliance
By managing algae pressure earlier, farms may reduce reliance on chemical interventions where appropriate and permitted.
Improved Operational Predictability
More stable fouling behaviour supports better planning of maintenance and cleaning cycles.
Passive, Low-Intervention Operation
Once deployed, the system requires minimal active management during operation.
Commercial & Deployment Pathway
Step 1: Site Assessment
Review of farm layout, environmental conditions, and operational objectives.
Step 2: Trial or Initial Deployment
Defined trial scope with agreed evaluation criteria.
Step 3: Outcome Review
Assessment of documented observations and operational impact.
If you require ESG or sustainability reporting alignment, we can define the trial metrics and documentation format during assessment.
Regulatory, Safety & Operational Alignment
Chemical-Free Operation
No chemical dosing is introduced by the ultrasonic system.
Electrical & System Safety
Low-power system design aligned with standard electrical safety requirements.
Designed for continuous operation in aquaculture environments without cavitation effects.
Aquatic Life Considerations
Farm Operations Compatibility
Deployment and operation are designed to avoid interference with normal farm activities.
