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.
Scenario modelling
Flexes feed load, TAN/O₂ per kg feed and biofilter kinetics — the levers that decide RAS CAPEX.
Calculator inputs
Trout/salmon 40–80, tilapia 60–120
Modern RAS 3–10%

Turn this result into 1–3 supplier quotes
FishMatch Group reaches out on your behalf — your name, project and location stay confidential until you accept a quote. No sign-up, no listing fees, buyers never pay.
How supplier matching works
- 1. Private brief. Your spec goes only to manufacturers we have selected for the right category, capacity and export experience.
- 2. Confidential outreach. Suppliers see the technical spec — not your name, company or exact location — until you accept a quote.
- 3. 1–3 comparable quotes. Typically within 5–10 business days, aligned on scope so you can compare like-for-like.
- 4. Financing intro (optional). If needed, we introduce your project to a financing partner. No fee to buyers.
Notes
- Add safety factors of 20–30% on biofilter and oxygen for peak feeding, disease events and startup.
- Denitrification, CO₂ stripping and solids handling are sized separately — request our full RAS engineering package.
