Planning — foundational work still open, but structured RFQs feasible
- Energy plan: Grid connection secured
- CAPEX clarity: USD 2M–10M — mid commercial
- Sign a site option or lease for at least 20 years
- Commission water lab tests (salinity, TAN, iron, TDS) and file abstraction permit
- Engage local permitting consultant and file EIA scoping
- Secure at least one signed LOI from a processor or importer
Indicative execution readiness. Not a credit decision or engineering warranty.
System stack
Surface aeration
- • Paddlewheel aerators (1–4 HP) for circulation plus transfer
- • Aspirator / injector aerators for deeper ponds
- • Long-arm aerators where sludge centralisation matters
- • Corrosion-rated units for brackish and marine ponds
Diffused & fine-bubble
- • Regenerative or Roots blowers with header and lateral grids
- • Micro-bubble diffuser tubing or disc arrays
- • Higher SAE than surface units where depth allows
- • Air header layout designed for even pressure distribution
Oxygen supplementation
- • PSA oxygen generator or LOX tank for peak / emergency load
- • Oxygen cones or diffusers on critical ponds
- • Emergency oxygen protocol for disease or heatwave events
- • Dosing tied to DO alarm thresholds
Power & distribution
- • Motor-rated distribution boards per pond block
- • VFD or staged start to limit inrush current
- • Standby generator with automatic transfer
- • Optional solar hybrid on daytime aeration load
Monitoring & automation
- • Continuous DO and temperature probes per pond or block
- • Automatic aerator start / stop on DO setpoint
- • Alarm escalation (siren, SMS, app) on low DO or motor fault
- • Energy metering to track kWh per kg produced
Installation & O&M
- • Floats, anchoring and cable management rated for the site
- • Spare impellers, bearings, gearboxes and diffuser sections
- • Scheduled bearing and diffuser cleaning intervals
- • Operator training on DO-driven aeration scheduling
Project stages
- 1. Oxygen demand studyBiomass curve, temperature, salinity, sludge load, pre-dawn DO profile. 2–4 weeks.
- 2. Technology selection & layoutSurface vs diffused vs hybrid, HP/ha, per-pond placement, electrical single line. 3–5 weeks.
- 3. Neutral RFQAerators, blowers, diffusers, panels, probes — project-matched suppliers. 4–6 weeks.
- 4. Installation & commissioningElectrical works, anchoring, probe calibration, DO verification. 4–10 weeks.
- 5. Optimisation cycleTune scheduling against DO logs and energy per kg over one production cycle.
Main CAPEX drivers
Indicative share of total installed cost. Actual split varies by region, redundancy, automation and civil scope.
| Aerators / blowers and diffuser grids | 35–45% |
| Electrical distribution, cabling and panels | 18–25% |
| Standby generator and transfer equipment | 10–18% |
| DO monitoring and automation | 6–12% |
| Installation, anchoring and civil works | 8–12% |
| Spares and commissioning | 4–8% |
Bankability questions
- Is aeration sized from an oxygen-demand calculation, not a generic HP/ha rule of thumb?
- Is the pre-dawn DO minimum modelled at peak biomass and peak temperature?
- Is standby power sized for the critical aeration load, not just lighting and pumps?
- Are SAE (kg O₂/kWh) figures quoted under a stated standard rather than vendor claims?
- Is energy cost per kg produced modelled at current and stressed tariffs?
- Are spares and service coverage available in-country?
- Are DO probes maintained and calibrated on a documented schedule?
- Is CAPEX supported by at least two independent quotes?
Key project risks
- Under-sized aeration shows up only at peak biomass — usually the most expensive point in the cycle to fail.
- Vendor SAE ratings measured in clean water overstate field performance; derate for salinity and temperature.
- Single-source power without backup turns any outage into a mortality event.
- Poor aerator placement centralises sludge in the wrong place and reduces effective pond area.
- Neglected diffusers and bearings quietly erode oxygen transfer and raise energy cost per kg.

How does FishMatch Group source suppliers for this requirement?
You submit one structured request. We translate it into a technical RFQ, run it against qualified manufacturers and integrators in the relevant categories, and return normalised quotations you can compare side by side on scope, lead time and total cost of ownership.

No. Supplier identities stay confidential during discovery and evaluation. You receive anonymised, comparable technical and commercial packages, and introductions happen only after both sides are qualified and agree to proceed.
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.
