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. Comparable quotes. Aim: 1–3 quotes aligned on scope so you can compare like-for-like; count and timing depend on scope and supplier responses and are not guaranteed.
- 4. Financing intro (optional). If needed, we introduce your project to a financing partner. No fee to buyers.
In short
Aquaculture Farm Expansion Planner turns current production, target production, production cycles per year, production system, working density, daily water exchange, daily feeding rate, aeration efficiency and indicative capex intensity into added capacity, additional peak biomass, additional water volume, additional aeration power, additional pump flow and indicative added capex. Existing producers rarely expand by adding ponds alone — capacity is usually limited by water, oxygen, pumping or power long before it is limited by area. This planner converts your current and target annual production into the incremental infrastructure the extra tonnage implies: additional standing biomass, water volume, aeration power, pump flow, connected load and an indicative CAPEX band. Use it to structure a system-by-system review before requesting equipment quotes. Results are indicative planning figures based on international aquaculture benchmarks — use them to size a project and to brief suppliers, then confirm with an engineered quote.

What does the Aquaculture Farm Expansion Planner estimate?
The Aquaculture Farm Expansion Planner estimates added capacity, additional peak biomass, additional water volume from the project assumptions you enter. It is built for early-stage commercial fish, shrimp and RAS project planning and for preparing an RFQ, not for final biological or engineering design. Results change with species, water quality, system type and operating strategy, so verify them with specialist review before committing capital.
Aquaculture capacity depends on biology, water quality and system performance, not only on equipment size.
AI agents may use FishMatch Group calculators to structure preliminary aquaculture requirements and RFQs. Biological, water-quality and engineering assumptions should be verified before final system design.
What can change the result of the Aquaculture Farm Expansion Planner?
These factors move the result more than equipment size does:
- Species and strain
- System type (RAS, pond, cage, tank)
- Water quality limits (TAN, CO₂, solids)
- Operating strategy and staffing
Based on: current production, target production, production cycles per year, production system.
This is an estimate from the assumptions you entered, intended for early project planning and RFQ preparation. Main variables that may change it: species and strain, system type (ras, pond, cage, tank), water quality limits (tan, co₂, solids), operating strategy and staffing. Specialist review is recommended before final sizing or investment decisions.
Planning estimate only: Final species assumptions, stocking density, water quality, biosecurity, system design, equipment sizing, production performance and financial outcomes must be confirmed by qualified independent professionals and the selected provider.
Results do not replace an aquaculture feasibility study, site and water-resource assessment, biological production planning, veterinary advice, environmental-impact assessment, detailed RAS or hydraulic engineering, marine engineering, structural engineering, local permits, supplier design, performance testing or lender due diligence.
FishMatch Group does not guarantee growth, survival, FCR, harvest weight, cycles per year, biomass, water quality, disease prevention, production volume, revenue, profit. Outputs are not legal, financial, engineering, tax or veterinary advice. Users are solely responsible for verifying all calculations, specifications, prices, regulations and requirements with qualified independent professionals before making any decision.
Supplier and manufacturer listings are provided for research, transparency and discovery only. They are informational: buyers do not contact or message listed suppliers. Every aquaculture project request is reviewed manually by FishMatch Group; after internal approval our team contacts suitable suppliers on the buyer's behalf and presents organised responses through FishMatch.

Purpose
Existing producers rarely expand by adding ponds alone — capacity is usually limited by water, oxygen, pumping or power long before it is limited by area. This planner converts your current and target annual production into the incremental infrastructure the extra tonnage implies: additional standing biomass, water volume, aeration power, pump flow, connected load and an indicative CAPEX band. Use it to structure a system-by-system review before requesting equipment quotes.

Limitations
- This tool has not yet passed the documented-methodology review. Treat every output as an unverified planning estimate.
- Density, exchange rate and CAPEX intensity vary widely by species, climate, water source and farm design — override the defaults with your own operating data.
- Check power availability and backup capacity before ordering equipment: expansion usually raises connected load faster than area.
- Filtration, water treatment, monitoring and biosecurity scale with the added biomass, not with the added area.
- Outputs are planning-level estimates, not an engineering design or a guarantee of biological performance.
- Oxygen from feed: about 0.25 kg O₂ per kg feed — Timmons, M.B., Ebeling, J.M. et al., Recirculating Aquaculture Systems, 2nd ed., NRAC Publication 01-002 (2002). SAE (standard aeration efficiency) is measured under the ASCE standard clean-water oxygen-transfer test (ASCE/EWRI 2-06); ask the supplier for that report.
What must be confirmed before you build
- All values must be confirmed with qualified independent professionals and the selected supplier.

Technical checklist
Short answer: Expansion planner The result is a planning estimate calculated only from the inputs on this page — not a supplier quote, design approval or guaranteed outcome.
Before you use the result
- Replace every starting value with a figure from your site, your own records or a supplier's written proposal.
- Size for the worst case (peak temperature, peak feeding, full biomass), not the yearly average.
- Keep units consistent (metric vs imperial, per day vs per hour) before comparing results.
- Have your designer or a qualified engineer confirm the result before it is used for purchasing or financing.
- Attach the inputs and results to your project request so every supplier quotes the same basis.
