RAS sizing and cost in Vietnam.
Vietnamese RAS and semi-RAS investment centres on indoor shrimp nurseries and grow-out, pangasius and tilapia hatcheries, and biosecure upgrades to existing pond farms in the Mekong Delta. Warm water shrinks biofilter volume but raises oxygen duty; salinity, heat load and power reliability then dominate the cost model. Size first, then price against the Vietnamese benchmarks below.
Species in scope: Whiteleg shrimp (indoor nursery and grow-out), pangasius, tilapia, marine finfish hatcheries
Size the system for Vietnam conditions
Run the sizing first. Tank volume, recirculation flow, biofilter media and oxygen duty are what turn a per-tonne benchmark 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.
Trout/salmon 40–80, tilapia 60–120
Modern RAS 3–10%
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.

What is different about RAS projects in Vietnam
Warm water: smaller biofilter, harder oxygen duty
At 28–30 °C nitrification is fast, so media volume per kg of feed is lower than in cold-water systems. The trade-off is dissolved-oxygen headroom: saturation is low, respiration is high, and oxygen supply plus emergency backup becomes the critical design item.
Salinity and materials selection
Brackish and marine shrimp systems need corrosion-appropriate pumps, blowers, fittings and structural details. A freshwater bill of materials quoted against a saline system is a common and expensive bid error — state design salinity in the RFQ.
Power reliability and heat
Aeration and oxygen loss during a short outage is the main mortality risk. Full standby generation with automatic transfer, plus emergency oxygen, is standard. Cooling and heat rejection also matter more than in temperate projects.
Biosecurity as the commercial driver
Most Vietnamese indoor shrimp projects are justified by survival and disease control, not by water saving. Filtration, disinfection, water treatment on intake and zoning between production units should be specified explicitly, because that is where the return comes from.
Vietnamese RAS sizing and cost benchmarks
Planning-grade bands for early budgeting and bid sanity checks — not quotations. Final pricing depends on site, scope and specification.
| Parameter | Typical range | Note |
|---|---|---|
| Typical project scale | 100–1,000 t/y shrimp, or nursery capacity in post-larvae per cycle | Multi-phase nursery-plus-grow-out layouts are the norm. |
| CAPEX per tonne (indoor shrimp RAS) | USD 9,000–18,000 /t/y | Planning band; lower where existing ponds and buildings are reused. |
| CAPEX per tonne (pangasius/tilapia RAS) | USD 7,000–14,000 /t/y | Warm-water biofilter and simpler materials keep this below marine systems. |
| Grow-out density (indoor shrimp) | 3–8 kg/m³ (raceway), higher in nursery | Shrimp density is area- and oxygen-driven, not directly comparable with finfish. |
| Specific energy use | 2.5–5 kWh/kg produced | Aeration and oxygenation dominate; cooling adds in the hot season. |
| New-water exchange | 2–10% of system volume per day | Biofloc-assisted and partial-reuse designs sit at the upper end. |
Operator availability in Vietnam
- Vietnam has a very large pond-aquaculture workforce, so farm labour is readily available and low-cost — but pond experience does not transfer directly to closed-system water-quality management.
- Plan a structured training programme for biofilter management, oxygen control and alarm response. Most successful projects run 2–4 weeks of supplier-led training plus a supervised first cycle before handing the system over.
- Vietnamese-language documentation, HMI and training are essential for operational safety and should be a stated deliverable in the RFQ, not an assumed extra.
- Local service and spare-parts availability vary sharply between imported and regionally assembled equipment. Ask each bidder to state spare-parts lead time into Vietnam and whether a local technician is available for callouts.

RAS in Vietnam — FAQ
Tiếng Việt
Chi phí hệ thống RAS nuôi tôm trong nhà tại Việt Nam là bao nhiêu?
Ở mức lập kế hoạch, RAS nuôi tôm trong nhà tại Việt Nam vào khoảng 9.000–18.000 USD cho mỗi tấn công suất năm, và thấp hơn nếu tận dụng ao, nhà xưởng hoặc hạ tầng sẵn có. RAS cá tra và cá rô phi thường ở mức 7.000–14.000 USD mỗi tấn.
Nước ấm có làm hệ thống RAS rẻ hơn không?
Một phần. Ở 28–30 °C quá trình nitrat hóa diễn ra nhanh nên thể tích giá thể lọc sinh học nhỏ hơn, nhưng độ bão hòa oxy thấp và nhu cầu hô hấp cao khiến hệ thống cấp oxy và dự phòng khẩn cấp trở nên lớn hơn và quan trọng hơn.
Việt Nam có sẵn nhân sự vận hành RAS không?
Lao động nuôi trồng thủy sản rất dồi dào, nhưng kinh nghiệm vận hành hệ thống tuần hoàn còn hạn chế so với nuôi ao. Nên dự trù chương trình đào tạo do nhà cung cấp thực hiện, tài liệu tiếng Việt và một chu kỳ sản xuất đầu tiên có giám sát.

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.
