Aquaculture Aeration Calculator
Aeration is sized against peak oxygen demand, not average demand. This planning tool converts species, biomass and water temperature into an oxygen load, then divides by the standard aeration efficiency (SAE, kg O₂ per kWh) of the transfer method you intend to use — paddle wheel, diffused aeration, biofloc air grid or RAS oxygenation. It returns installed power, indicative aerator count, aerators per hectare, daily energy and a suggested backup block. Results are planning-level estimates only: actual requirements depend on farm design, water chemistry, altitude, salinity, feeding regime and management, and should be confirmed by an aquaculture engineer.
Scenario modelling
Flexes peak biomass, temperature and transfer efficiency — the three variables that decide whether aeration holds during a heat event.
Calculator inputs
Biomass at the heaviest point of the cycle, not at stocking.
Use total area of the ponds or tanks served.
2 HP paddle wheel ≈ 1.5 kW.

Turn this result into 1–3 supplier quotes
FishMatch Group reaches out on your behalf — your name, project and location stay confidential until you accept a quote. No sign-up, no listing fees, buyers never pay.
How supplier matching works
- 1. Private brief. Your spec goes only to manufacturers we have selected for the right category, capacity and export experience.
- 2. Confidential outreach. Suppliers see the technical spec — not your name, company or exact location — until you accept a quote.
- 3. 1–3 comparable quotes. Typically within 5–10 business days, aligned on scope so you can compare like-for-like.
- 4. Financing intro (optional). If needed, we introduce your project to a financing partner. No fee to buyers.
Notes
- Aerator count is a planning estimate. Placement, circulation pattern and pond geometry matter as much as installed power.
- Oxygen demand peaks 2–4 hours after feeding and again before dawn — size for the worst hour of the cycle.
- Water-quality problems have multiple possible causes. Aeration is one factor among stocking, feeding, biofiltration, exchange and waste management.
- Keep an independently powered backup aeration block: most catastrophic losses follow a power or blower failure, not a design error.
- This tool is not a substitute for farm-specific aquaculture engineering or biological assessment.
