planning

Planning — foundational work still open, but structured RFQs feasible

Strengths
  • Energy plan: Grid connection secured
  • CAPEX clarity: USD 2M–10M — mid commercial
Do next
  • 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.

Project stages

  1. 1. Oxygen demand study
    Biomass curve, temperature, salinity, sludge load, pre-dawn DO profile. 2–4 weeks.
  2. 2. Technology selection & layout
    Surface vs diffused vs hybrid, HP/ha, per-pond placement, electrical single line. 3–5 weeks.
  3. 3. Neutral RFQ
    Aerators, blowers, diffusers, panels, probes — project-matched suppliers. 4–6 weeks.
  4. 4. Installation & commissioning
    Electrical works, anchoring, probe calibration, DO verification. 4–10 weeks.
  5. 5. Optimisation cycle
    Tune scheduling against DO logs and energy per kg over one production cycle.

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.

Common questions

As a planning baseline, semi-intensive fish ponds use roughly 4–12 HP per hectare and intensive vannamei shrimp ponds 16–30+ HP per hectare. The correct figure comes from an oxygen-demand calculation at peak biomass, peak water temperature and worst-case pre-dawn conditions, not from a rule of thumb.

Paddlewheels combine oxygen transfer with circulation and sludge centralisation, which is why they dominate shrimp ponds. Diffused fine-bubble systems generally deliver higher kg O₂ per kWh in deeper ponds but do less to move water. Many intensive farms run a hybrid: diffused for base load, paddlewheels for circulation and peak demand.

Equipment cost is commonly USD $1,500–$4,000 per installed HP once electrical distribution, anchoring and installation are included. Farm-wide packages across multiple ponds routinely exceed USD $250K, which is the project band FishMatch works in. Energy, not hardware, dominates lifetime cost.

Yes. Intensive ponds at peak biomass can drop below critical dissolved oxygen within one to three hours without aeration. A standby generator with automatic transfer covering the full critical aeration load — plus emergency oxygen for high-value stock — is standard practice.

No. FishMatch Group is an independent B2B procurement and sourcing platform. We help buyers define aeration requirements, run a confidential RFQ to project-matched third-party manufacturers, compare quotes on a like-for-like basis and explore independent financing options. Supply, installation and warranties come solely from third-party suppliers.

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.
