Indicative CAPEX, OPEX and payback for a new recirculating aquaculture system, based on production target, species and region. Order-of-magnitude only — for an engineered estimate, request a pre-project review.
A commercial RAS system typically costs USD 9,000–25,000 per tonne of annual capacity for equipment and installation, with operating cost of roughly USD 2–6 per kilogram harvested. Species, water temperature, oxygen strategy, redundancy and local build costs move the figure far more than tank volume does. Set the three inputs below to see an order-of-magnitude budget, then size the system itself further down the page.
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.

This is the calculation the tool runs when you select Atlantic salmon, 500 tons per year and Europe. Every figure is an order-of-magnitude benchmark, not a quotation.
| Line | How it is calculated | Result |
|---|---|---|
| CAPEX | $22,000 per ton of annual capacity × 500 t × 1.15 Europe factor | $12.65M |
| Annual OPEX | $5.20 per kg × 500,000 kg × 1.15 Europe factor | $2.99M |
| Annual revenue | $8.50 per kg farm-gate × 500,000 kg | $4.25M |
| Gross margin | Revenue − OPEX | $1.26M |
| Simple payback | CAPEX ÷ gross margin (before financing, tax and depreciation) | ≈ 10.0 years |
Change the species to tilapia and the same 500 t/year project drops to roughly $5.2M CAPEX, because tilapia tolerates warmer water, higher density and far less chilling and oxygenation capacity than salmon.
Sets the CAPEX per ton, OPEX per kg and farm-gate price benchmark. Cold-water species need chilling, deeper tanks and more oxygenation, so they cost more per ton of capacity than warm-water species.
Not sure yet? Run salmon and tilapia to see the realistic spread before choosing.
Target harvested biomass per year, not tank volume or standing stock. CAPEX per ton falls slowly with scale in reality; this tool keeps it linear so the output stays conservative for small projects.
Below roughly 200 t/yr, expect the real figure to sit above the estimate.
A multiplier on both CAPEX and OPEX covering local construction, energy and labour cost. Revenue is left unadjusted because farm-gate prices are set by the market you sell into, not where you build.
If your electricity tariff is unusually high or low, treat energy as the biggest swing factor.
Drum filters, biofilters, oxygen cones, degassers, tanks, pumps, PLC controls, building shell and installation, benchmarked per ton of annual production capacity.
Feed (largest single cost), juveniles, energy, oxygen, labour, water, maintenance and overheads per kg of fish harvested.
Adjusts for local construction, energy and labour costs. Asia and Latin America typically build cheaper; Europe and USA are more expensive.
A commercial RAS typically costs USD 8,000–20,000 per tonne of annual capacity for equipment and installation, with running costs of roughly USD 2–5 per kilogram. Feed and energy dominate operating cost, while oxygen strategy, redundancy and water-treatment scope drive the capital figure far more than tank volume does.
Sizing outputs turn into money through a fairly stable cost structure. Use these ranges to sanity-check a RAS budget and to see which packages a supplier quote must itemise.
Tank count and material (GRP, PP, concrete), freeboard and drainage design.
Peak flow, screen micron rating and backwash water recovery.
Daily feed load and TAN target, not tank volume.
Density, temperature and whether LOX or on-site oxygen generation is used.
Turnover rate, total head and level of pump redundancy.
Biosecurity policy, make-up water quality and intake source.
Sensor count, redundancy and remote alarm requirements.
Automation level and batch handling strategy.
Grid reliability and permitted downtime before biomass loss.
Travel distance, local labour, and the scope split with the contractor.
Biological and economic FCR, feed price and mortality.
Pumping head, oxygen strategy, heating/cooling and local kWh price.
Stocking weight, survival and supplier quality.
Automation level, shift coverage and local wages.
LOX delivery price versus on-site generation, alkalinity dosing.
Equipment quality, water chemistry and service coverage in-country.
Anonymised planning envelopes from comparable commercial projects. References are internal codes; supplier and client identities are never published.
Full land-based RAS, 12 grow-out tanks, dual loop
Cost driven by oxygen strategy and redundancy, not tank volume; a second loop was specified for biosecurity separation.
Single-loop RAS with moving-bed biofilter
Warm-water species keeps heating low; feed and energy price dominate cost per kilogram.
Nursery + grow-out raceways, biofloc-assisted RAS
Heating and aeration dominate energy; survival assumptions move cost per kilogram more than equipment price.
Hybrid flow-through with partial recirculation
Partial reuse cuts CAPEX versus full RAS but ties the project to water availability and discharge limits.
Cost follows sizing. Enter the same production target here to get tank volume, flow, oxygen demand and filtration ranges — the packages a supplier has to price in an RFQ.
Recirculating aquaculture systems (RAS) are sized around standing biomass, feed load and target density. This tool derives system volume, daily make-up water, TAN production, MBBR biofilter volume and oxygen demand — the five numbers every RAS engineer starts with.
Trout/salmon 40–80, tilapia 60–120
Modern RAS 3–10%

Short answer
Submit one structured request for RAS Cost Calculator. FishMatch Group translates it into a technical RFQ, runs a confidential sourcing round with project-matched international suppliers, and returns comparable quotations. No fee is charged to the buyer, and your identity and project details stay private until you choose to proceed.
Before you request quotes
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.
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.
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.
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.
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.
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.
