RAS sizing and cost in the United States.
Plan a RAS project in United States from measured site conditions and a defined production brief, not a country-average equipment price. The FAO country data below describe aquaculture production across farming systems; they do not establish RAS capacity or costs.
FAO production groups: Miscellaneous freshwater fishes; Oysters; Freshwater crustaceans; Clams, cockles, arkshells
Sourced aquaculture evidence for United States
FAO reports 456,367 tonnes live weight of aquaculture production for United States of America in 2023, compared with 471,430 tonnes in 2018. Totals sum rounded species-group records.
| FAO species group | Tonnes | FAO flags |
|---|---|---|
| Miscellaneous freshwater fishes | 165,579 | I |
| Oysters | 155,516 | I |
| Freshwater crustaceans | 42,496 | Official |
| Clams, cockles, arkshells | 42,303 | I |
Flags from FAO: E = FAO estimate, I = imputed, N = not significant (<0.5 t), B = series break. No flag = official value.
National production includes different farming systems; it does not measure RAS capacity, project costs, supplier availability or commercial feasibility.

Size the system for United States conditions
Run the sizing first. Tank volume, recirculation flow, biofilter media and oxygen duty are what turn a defined scope into a budget that survives a bid comparison.
RAS sizing calculator
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.
Example — check the sourced limits in the Stocking Density Calculator (e.g. SRAC 282: tilapia 60–120 with pure oxygen)
Example — use your system designer's figure
From your feed bag / feed supplier's specification
Example — use the media supplier's tested rate at your temperature. Measured in a working RAS: 127.6 ± 58.3 g TAN/m³·day (Pfeiffer & Riche 2011, Florida pompano)
250 g from Timmons & Ebeling; use your designer's figure if different
Example — use your system designer's recirculation rate
Example — from your designer's hydraulic calculation
Example — read it off the pump's performance curve at your flow and head
Blowers, UV, heating, lights — from your equipment list
Example — from your power bill or utility tariff
Your water supplier's tariff; 0 if you use your own well

What is different about RAS projects in United States
United States: production context
Largest reported FAO aquaculture groups: Miscellaneous freshwater fishes; Oysters; Freshwater crustaceans; Clams, cockles, arkshells. A group total does not establish suitability for a particular RAS species or site.
Water and permitting evidence
Obtain site water analyses, abstraction and discharge conditions, and current written approvals from the responsible authority before fixing the treatment scope.
Power and temperature evidence
Obtain the actual connection capacity, tariff, outage history and seasonal intake temperatures. Size life-support loads and backup from the equipment schedule.
Delivered cost scope
Compare dated quotations with the same capacity, materials, redundancy, civil works, freight, installation, training and acceptance criteria. Confirm local tax treatment separately.
US RAS budget evidence requirements
No verified national RAS price series is available. Pricing requires dated quotations for the site, scope and specification.
| Parameter | Evidence status | Note |
|---|---|---|
| Country RAS CAPEX | Not verified | Obtain dated, scope-specific quotations; no modelled national cost factor. |
| Electricity budget | Site inputs required | Equipment kW × operating hours × actual tariff. |
| Water and feed budget | Site inputs required | Use measured demand and dated commercial quotes, not national production totals. |
Operator availability in United States
- Verify species-specific operating experience, commissioning support, documentation language, training, response arrangements and spares with each bid. No local recruitment availability or lead time has been verified here.
Price and stress-test the sized system
Check the water budget, cost per kilogram and bid normalisation against the same scope before you talk to anyone.
- RAS system sizing calculator
Size tanks, flow rate, biofilter volume and oxygen supply from your target biomass and feed load.
Open calculator - RAS water turnover & exchange rate calculator
Check hydraulic retention time and daily new-water exchange against stocking density and feed input.
Open calculator - RAS feasibility & production cost calculator
Estimate cost per kilogram produced — feed, energy, oxygen, labour — before committing CAPEX.
Open calculator - RAS bid normalizer — compare supplier quotations
Compare RAS supplier quotes on identical scope so price, capacity and lead time line up line-for-line.

RAS in United States — FAQ
FishMatch Group is a managed sourcing service. Every brief is reviewed by a person before sourcing begins — suppliers are never contacted automatically and supplier identities are never exposed.
Short answer
What is the fastest way to get quotes for USA?

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.
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.
