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.

Main CAPEX drivers
Indicative share of total installed cost. Actual split varies by region, redundancy, automation and civil scope.
| Civil works & building envelope | 20–30% |
| RAS equipment (filtration, biofilters, tanks, piping) | 28–38% |
| Oxygen generation & life support | 8–12% |
| Electrical, controls & SCADA | 8–12% |
| HVAC & heating | 6–10% |
| Engineering, permits & PM | 6–10% |
| Contingency (recommended) | 10–15% |
Bankability questions
- Is the water source characterized and is makeup reliably available year-round?
- Is grid electricity stable and is the tariff modeled for 10 years?
- Is there an offtake agreement or LOI with a processor or wholesaler?
- Is fingerling supply secured with at least two qualified hatcheries?
- Is a qualified operator identified with prior RAS experience?
- Are permits (environmental, water discharge, construction) achievable in the target timeline?
- Is CAPEX supported by class-3 estimates from at least two independent sources?
- Is OPEX modeled at pessimistic, base and optimistic scenarios (FCR, mortality, energy)?
- Is technical DD available for the RAS technology provider?
- Is financing (equity, senior debt, ECA, leasing) matched to cash-flow ramp-up?
Key project risks
- Biological ramp-up slower than plan (first 9–15 months usually under-produce).
- Energy price volatility hits profitability — hedge or model conservatively.
- Single points of failure in oxygen or power cause catastrophic losses without redundancy.
- Fingerling quality variability affects survival and growth — dual-source and screen.
- Discharge and biosecurity regulation can tighten — design for tomorrow's rules.

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.
