RAS Planning Topic Cluster
A structured outline of FishMatch Group's recirculating aquaculture planning content — the pillar article plus every supporting guide, grouped by planning stage. Use it as a reading path before you brief suppliers or lenders.
Why Successful Aquaculture Projects Begin Long Before Equipment Is Purchased
The 5,500-word executive guide that anchors this cluster. It explains why species, water, energy and financing decisions must be locked before any RFQ is issued — and how each of the supporting articles below fits into that sequence.
Read the pillarRAS System Cost Breakdown: CAPEX, OPEX and Real Project Examples
The line-by-line money page of this cluster — CAPEX shares for every subsystem, operating cost per kilogram, the eight variables that move the number, and four real-world RAS projects from 100 t to 2,000 t per year.
Open the cost breakdown RAS cost & design pillar guide RAS system cost calculator RAS sizing calculator — tanks, flow, biofilter and oxygen RAS system case studies — real projects with CAPEX, OPEX and outcomes The 6-step aquaculture procurement sequence — sizing to human-reviewed RFQ- RAS Design Principles for Commercial Fish Farms
Ten engineering decisions in order: feed load, density, flow, solids, biofilter, oxygen, redundancy, biosecurity, energy and specification.
- Fish Farming Economics: Cost Per Kilogram
How feed, juveniles, energy, labour and mortality build production cost — and how to stress the model before a lender does.
- Aquaculture Trends 2026
Energy-led system selection, staged land-based capital, post-smolt growth, automation and tightening discharge rules.
RAS planning calculators
Turn the concepts in this guide into numbers: size the system, check the water budget, test feasibility and compare bids before you brief suppliers.
- RAS system sizing calculator
Size tanks, flow rate, biofilter volume and oxygen supply from your target biomass and feed load.
Open calculator - RAS water turnover & exchange rate calculator
Check hydraulic retention time and daily new-water exchange against stocking density and feed input.
Open calculator - RAS feasibility & production cost calculator
Estimate cost per kilogram produced — feed, energy, oxygen, labour — before committing CAPEX.
Open calculator - RAS bid normalizer — compare supplier quotations
Compare RAS supplier quotes on identical scope so price, capacity and lead time line up line-for-line.

1. Design & sizing fundamentals
Lock species, biomass curve, feed load and hydraulic assumptions before any vendor is briefed. These pieces mirror the pillar's ‘decide before you buy’ principle.
RAS Design Fundamentals: What to Lock Before You Buy Equipment
The engineering inputs — species, density, water budget, redundancy — that must be frozen before an RFQ leaves your desk.

Translate feed load into oxygen, CO₂ stripping and biofilter capacity so equipment specs are derived, not guessed.

2. Water quality & oxygen management
Bankable RAS projects live or die on water chemistry and dissolved oxygen headroom. These guides map to the pillar's operating-envelope section.
Water Quality Management in Commercial Aquaculture
Parameter targets, monitoring cadence and alarm thresholds that lenders and insurers expect to see documented.

How to design DO redundancy — LOX, blowers, emergency O₂ — so a single failure never becomes a mortality event.

3. Biosecurity, HACCP & energy
Operating cost and risk profile are set at design stage. These articles cover the compliance and OPEX levers the pillar flags as make-or-break.
Biosecurity Zoning and HACCP for Commercial Aquaculture
Zoning, flow control and HACCP structures that satisfy export authorities and reduce disease risk from day one.

Where kWh actually go in a modern RAS and which design choices move OPEX the most over a 10-year horizon.

4. Procurement & project financing
Once the design is frozen, the pillar hands off to a vendor-neutral RFQ and a lender-ready financing package. These two pieces close the loop.
Vendor-Neutral Aquaculture Procurement: Running a Buyer-First RFQ
How to structure an RFQ that compares suppliers on identical, engineering-grounded scope — not on marketing decks.
