Aquaculture Water Consumption Calculator

Water permits are the #1 approval risk for commercial aquaculture. This tool converts system volume, exchange rate and evaporation into daily/annual make-up water and per-kg-fish intensity — the number regulators, banks and ESG auditors actually ask for.

Scenario modelling

Flexes exchange rate, evaporation and tariff — the three water-permit variables.

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

Water abstraction permits often cap m³/day — check limits before finalising system design.
RAS cuts water use 90–99% vs flow-through and is the only route in water-stressed regions.
Reject water requires effluent treatment — see the Wastewater / Effluent center.
