Calculateur de coût d'un système RAS
CAPEX, OPEX et retour indicatifs pour un nouveau système aquacole en recirculation (RAS), selon l'objectif de production, l'espèce et la région. Outil de préqualification : pour un budget d'ingénierie, demandez une revue de projet.
Un système RAS commercial coûte généralement 9 000 à 25 000 USD par tonne de capacité annuelle, équipement et installation compris, avec un coût d'exploitation d'environ 2 à 6 USD par kilogramme récolté. Les espèces d'eau chaude comme le tilapia se situent en bas de la fourchette, le saumon en haut.

Postes de CAPEX et d'OPEX
- Bâtiment et infrastructure
20–30 % du CAPEX total, selon le climat et le terrain.
- Bassins et hydraulique
15–20 % du CAPEX ; nombre et profondeur des bassins déterminants.
- Traitement de l'eau (tambour, biofiltre, dégazeur, UV)
30–35 % du CAPEX — le poste critique.
- Oxygène et énergie
10–15 % du CAPEX : LOX, surpresseurs, redondance de production.
- Automatisation et supervision
5–8 % du CAPEX : alarmes et architecture de secours.
- Aliment (OPEX)
Premier poste d'exploitation, typiquement 40–50 %.
- Énergie et oxygène (OPEX)
20–30 % du coût d'exploitation ; le tarif électrique est la variable clé.
- Main-d'œuvre, juvéniles, maintenance (OPEX)
Les 25–35 % restants, selon le niveau d'automatisation.

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.
