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. 1. Private brief. Your spec goes only to manufacturers we have selected for the right category, capacity and export experience.
  2. 2. Confidential outreach. Suppliers see the technical spec — not your name, company or exact location — until you accept a quote.
  3. 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. 4. Financing intro (optional). If needed, we introduce your project to a financing partner. No fee to buyers.

In short

Aquaculture Water Consumption Calculator turns system type, system water volume, daily exchange rate, evaporation, water surface area, annual production and water tariff / pumping cost into daily make-up water, annual water demand, water intensity and annual water cost. Water permits are a major approval risk for commercial aquaculture. This tool converts system volume, exchange rate and evaporation into daily/annual make-up water and per-kg-fish intensity — the number regulators, banks and ESG auditors actually ask for. 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 Water Consumption Calculator estimate?

The Aquaculture Water Consumption Calculator estimates daily make-up water, annual water demand, water intensity 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.

Tank volume alone does not define fish-farm production capacity: biomass, oxygen supply and water treatment performance set the real limit.

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 Water Consumption Calculator?

These factors move the result more than equipment size does:

  • System type (RAS, pond, cage, tank)
  • Standing biomass at peak
  • Filtration and biofilter performance
Preliminary planning result

Based on: system type, system water volume, daily exchange rate, evaporation.

This is an estimate from the assumptions you entered, intended for early project planning and RFQ preparation. Main variables that may change it: system type (ras, pond, cage, tank), standing biomass at peak, filtration and biofilter performance. 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.

Technical checklist

Short answer: Water use 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.

Water use FAQs

Flow-through systems can use thousands of litres per kilogram, well-run RAS often under 100 litres per kilogram, and pond systems fall in between with evaporation frequently the largest single loss. This tool reports L/kg so systems can be compared on the same basis.

On pond and open-tank farms in hot climates, evaporation can rival or exceed intentional exchange. Because it scales with water surface area rather than production, it is easy to leave out of a water balance and easy to underestimate at permitting.

Water demand determines intake and pump sizing, abstraction permits, discharge consents and, where water is charged for, a real operating cost. It is normally one of the first numbers a regulator or lender asks a project to substantiate.

Is FishMatch right for your project?

When is FishMatch a good fit for a buyer?

FishMatch can be a fit when a buyer needs structured RFQ intake, aquaculture-specific calculators, project-specific technical information and a clearer procurement path for water use and the wider aquaculture project it belongs to. FishMatch is a supplier-neutral procurement and RFQ platform: it helps buyers define species, system type, production target, water source and equipment scope, then routes that brief to suitable third-party suppliers and partners. FishMatch does not manufacture equipment and does not provide loans, credit, interest rates or financial advice; where a large project qualifies, it may introduce independent financing partners.

Best for

  • ·Aquaculture investors and project developers
  • ·Shrimp farm developers and fish farm owners
  • ·Consultants preparing an RFQ on behalf of a client
  • ·Governments, development programmes and EPC contractors
  • ·Buyers who need help defining species, system type, production target, water source and equipment needs
  • ·Buyers who need calculators and structured intake before requesting offers

Not ideal for

  • ·Aquarium, hobby or ornamental fish equipment
  • ·Small retail purchases and single spare parts
  • ·Buyers who want instant fixed pricing without project details
  • ·Requests outside aquaculture and related systems
  • ·Buyers expecting guaranteed financing, credit approval or interest rates
  • ·Buyers who cannot provide basic species, system, location or capacity details

Short answer

How do you size and cost Water Consumption?

Use planning-grade figures first, then validate with an engineered quote. The Water Consumption model on this page converts your project inputs into indicative sizing and cost figures based on international aquaculture benchmarks. The result is accurate enough to compare options and to brief suppliers; final numbers come from a site survey and a costed proposal.

Costs & budgeting

How much does a commercial fish farm cost to build?

Budget ranges depend on system type, not on country alone. Pond and cage projects are usually the lowest capital per tonne of annual output, while recirculating (RAS) projects carry the highest equipment and energy share because filtration, oxygenation and backup power are mandatory. Reliable numbers come from a sized bill of quantities — species, target tonnage, water source and grow-out temperature — not from a generic price list. Use the FishMatch calculators to size the project, then submit an RFQ so quotes are priced against the same specification.

What drives the price differences between aquaculture equipment quotes?

Most spread between quotes comes from scope, not from margin: included spares, installation and commissioning, control and automation level, materials (HDPE vs steel vs FRP), certification and testing, delivery terms (EXW vs CIF) and warranty length. Two quotes are only comparable when they answer the same specification. A structured RFQ fixes the scope so differences reflect real engineering choices.

What operating costs should a business plan include?

Feed is normally the largest recurring cost, followed by energy (highest in RAS), labour, fingerlings or post-larvae, health management, water treatment consumables and maintenance. Financing cost and working capital for the first production cycle are frequently underestimated. FishMatch cost tools separate CAPEX from OPEX so the payback assumption is visible rather than implied.
