Recirculating aquaculture (RAS) systems — engineering & procurement
Land-based RAS for salmon, trout, tilapia, sea bass, shrimp and hybrid species. Independent process design, project-matched suppliers, banker-ready CAPEX.
- Investment$1M – $100M+
- Timeline12–24 months from concept to first stocking
- Capacity band200 t/yr niche RAS → 15,000 t/yr flagship facilities
ras systems we source, engineer and finance
Salmon, trout, sea bass and barramundi grow-out under one roof.
De-risks marine grow-out; reduces cage biomass and sea-lice pressure.
Combines biosecurity with lower energy for cold-water species.
Zero-exchange indoor grow-out with tight nitrogen control.
Scope of engagement
- Mass balance, oxygen budget, hydraulic sizing
- Mechanical filtration (drums), biofilters, CO2 stripping
- Oxygenation, ozone / UV disinfection, denitrification
- SCADA / automation and alarm architecture
- Building envelope, HVAC and energy strategy
- Financial model and lender-ready bankability pack
What you actually get
- Independent basis of design — not written by a single supplier
- Apples-to-apples RFQ across drum filters, MBBR, oxygenation vendors
- Energy and OPEX modelling that survives lender scrutiny
- Documented process guarantees, not marketing performance figures
Risks we design out of the RFQ
- · Undersized biofilter or CO2 stripping — the #1 cause of RAS re-designs
- · Sole-source turnkey contract with no independent design review
- · Under-modelled energy costs on cold-climate salmon RAS
What our engineers tell every buyer before signing
Vendor-neutral principles drawn from live ras systems projects. Apply these before your RFQ goes out — they change what suppliers can quote.
- 1Commission an independent basis of design first
The single biggest RAS cost driver — good or bad — is the process design document. Owning it independently prevents supplier lock-in and creates a real apples-to-apples RFQ.
- 2Size biofilter and CO2 stripping for the worst day, not the average
Under-sized biological treatment is the #1 cause of RAS re-designs. Model peak feed load, peak temperature and worst-case oxygen demand — then add safety margin.
- 3Model energy honestly for the local climate
Cold-climate salmon and warm-water tropical RAS have very different HVAC and pumping loads. Lender-grade OPEX models must reflect this — or the project fails financing due diligence.

Short answer
What is the fastest way to get quotes for RAS Systems?
Submit one structured request for RAS Systems. FishMatch Group translates it into a technical RFQ, runs a confidential sourcing round with project-matched international suppliers, and returns comparable quotations. No fee is charged to the buyer, and your identity and project details stay private until you choose to proceed.
- How it works:
- One structured request, human-reviewed before any supplier outreach
- Typical turnaround:
- Depends on scope and site data; no turnaround is guaranteed
- Confidentiality:
- Supplier names are never exposed during evaluation
- Cost to buyers:
- No fee charged to the buyer
Before you request quotes
Equipment scope
What equipment does a commercial aquaculture project actually need?
A grow-out project typically needs holding infrastructure (tanks, ponds or cages), water movement (pumps, piping, valves), aeration or oxygenation, water treatment appropriate to the system, feeding equipment, grading and handling gear, monitoring and alarms, and backup power. RAS adds mechanical filtration, biofiltration, degassing, disinfection and tighter process control. Hatchery and processing scopes are specified separately.
Which equipment should be specified before requesting quotes?
Specify the items whose sizing changes everything downstream: design biomass and stocking density, water exchange or recirculation rate, oxygen demand at peak temperature, and installed pumping head. With those four fixed, suppliers can quote aeration, filtration, pumps and power on the same basis. FishMatch calculators produce these figures and attach them to the RFQ.
Can equipment be sourced in stages?
Yes, and phased procurement is common. The usual sequence is water supply and holding infrastructure, then aeration and treatment, then automation and monitoring, then processing and cold chain. Staging works when interfaces and capacity headroom are defined at the start; otherwise later phases force replacement rather than addition.
