RAS / aquaculture sizing & CAPEX
Turn a production target into standing biomass, tank volume, water treatment duty and installed CAPEX for a recirculating aquaculture project.
Installed cost per tonne of annual capacity before region.
Civil works, labour and logistics move installed cost more than the machinery itself.
1,000 t/year requires about 12,778 m³ of tank volume and $8.07M – $10.93M of installed CAPEX.

Carries capacity, project type and the indicative budget band into a structured RFQ for FishMatch Group. Free for buyers.
Method and assumptions
- Standing biomass derived from annual production divided by harvest cycles, with a 1.15 sizing margin.
- Recirculation flow assumed at 0.6 m³/h per m³ of tank volume; make-up water at 3% of system volume per day.
- Feed, smolt/post-larvae supply, effluent permits and grid connection are excluded.
