RAS farm cost guide: realistic CAPEX and OPEX for 2026 projects
What land-based salmon, trout and shrimp RAS projects actually cost — broken down by capacity tier and what drives the price.
Recirculating Aquaculture Systems (RAS) are the most capital-intensive aquaculture format, and also the most misquoted. This guide gives realistic 2026 CAPEX and OPEX ranges so you can scope a project credibly before talking to suppliers.
CAPEX by capacity tier
Pilot (100–500 t/y): typically $4M–$10M turn-key, depending on species and climate.
Mid-scale (1,000–3,000 t/y): typically $30M–$80M, dominated by tank shells, biofilters and oxygenation.
Mega-farm (5,000+ t/y): typically $150M+, with civil works often >40% of the bill.
What drives the price
Site selection (proximity to ports, energy, water), species (salmon needs more denitrification than tilapia), biosecurity ambitions, and energy strategy. A facility in Saudi Arabia will pay more for cooling than a facility in Norway pays for heating.
OPEX rules of thumb
Feed: 40–55% of OPEX. Energy: 15–25%. Labour: 8–15%. Maintenance: 4–8%. Mortality reserves: 3–6%.
How to avoid the worst mistakes
Do not specify a system before securing power and water. Do not skimp on monitoring and alarms. Do not buy a biofilter sized for the brochure case — size it for your worst feed-input day.
Submit your project parameters and FishMatch will return anonymized bids from tier-1 RAS engineers.
