RAS sizing and cost in Ecuador.
Ecuador is the world's largest whiteleg shrimp exporter, and its recirculation investment is concentrated where it pays best: maturation units, hatcheries, and intensive nurseries that raise post-larvae to a robust stocking size before transfer to ponds. Biosecurity and water quality, not tonnage, are the design drivers. Size the system first, then apply the Ecuadorian benchmarks below.
Species in scope: Whiteleg shrimp (maturation, hatchery, nursery, some intensive raceway pre-grow), tilapia polyculture support
Size the system for Ecuador 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 Ecuador
The value is in the nursery, not full grow-out
Full recirculating grow-out rarely competes with Ecuador's low-cost pond production. The bankable RAS cases are maturation, hatchery and nursery stages, where survival, uniformity and disease exclusion carry a direct value per post-larva.
Biosecurity defines the specification
White spot, EHP and vibriosis pressure means intake sterilisation, strict zoning, footbaths, separate water loops per module and effluent disinfection are core scope. A hatchery specified without full intake treatment is not a cheaper hatchery — it is a different risk profile.
Warm seawater lowers heating but raises oxygen duty
At 28–31 °C heating is unnecessary but dissolved-oxygen headroom is minimal. Oxygenation, aeration redundancy and standby power sizing matter far more than biofilter volume in Ecuadorian designs.
Coastal water supply and salinity management
Estuarine intakes swing in salinity and turbidity through the rainy season. Beach wells or blended supply stabilise the nursery environment and reduce filtration duty, at a higher up-front cost that should be modelled explicitly.
Ecuadorian 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 | 50–500 million PL/year hatchery; 20–200 t/y nursery biomass | Sized in post-larvae, not tonnes of harvest. |
| CAPEX (hatchery, per million PL/year) | USD 6,000–14,000 | Planning band; includes intake treatment, algae/artemia and larval rearing. |
| CAPEX per tonne (intensive nursery) | USD 9,000–18,000 /t/y | Raceway or tank nurseries with recirculation and heating not required. |
| Nursery density | 1–5 kg/m³ (or 2,000–10,000 PL/m³ early stage) | Stage-dependent; uniformity matters more than peak density. |
| Specific energy use | 1.5–4 kWh/kg biomass produced | Pumping, aeration and oxygenation; no heating load. |
| New-water exchange | 10–50% per day in larval stages | Hatcheries are partial-reuse; disinfection duty scales with exchange. |
Operator availability in Ecuador
- Ecuador has one of the world's deepest shrimp technical labour pools — hatchery managers, larval-rearing technicians and pond agronomists are readily available and locally trained.
- Recirculation-specific skills (biofilter management, water-chemistry control at low exchange) are less common than larval husbandry; plan targeted training when moving a hatchery towards low-exchange operation.
- Wage levels and local availability make 24/7 staffing of a nursery practical, which is a genuine operational advantage over higher-cost markets.
- Specify supplier commissioning support and a spare-parts package in the RFQ regardless: for imported filtration, oxygen and instrumentation the parts lead time — not local skill — is the availability risk.

RAS in Ecuador — FAQ
Español
¿Tiene sentido un RAS de engorde completo en Ecuador?
Rara vez. El costo de producción en piscinas es tan competitivo que la recirculación total difícilmente compite. Los casos rentables son maduración, laboratorio de larvas y precría intensiva, donde la supervivencia y la uniformidad tienen valor directo por post-larva.
¿Cuánto cuesta un laboratorio de larvas de camarón en Ecuador?
Como referencia de planificación, 6.000–14.000 USD por millón de post-larvas de capacidad anual, incluyendo tratamiento de agua de entrada, alimento vivo y cría larvaria. Una precría intensiva ronda 9.000–18.000 USD por tonelada anual.
¿Hay personal técnico con experiencia en Ecuador?
Sí, Ecuador cuenta con uno de los equipos técnicos camaroneros más profundos del mundo. La brecha está en el manejo de recirculación con bajo recambio, que se cubre con capacitación específica y soporte de puesta en marcha del proveedor.

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.
