Premium marine fish and land-based RAS investment in Japan.
For commercial operators, integrators, developers and institutional projects — not backyard farming. Plan the marine fish (sea bass / bream / barramundi) project first, then source equipment and financing with the numbers already in hand.
- Land-based RAS
- Premium marine species
- Hatchery and nursery
- Backup and redundancy
- Energy costs
- Food-security investment
Indicative project plan
A 750 t/year marine fish (sea bass / bream / barramundi) project in ras (recirculating) (Japan) needs roughly 0.4 ha, 1,200 t of feed per year, 37 kW of aeration and an indicative CAPEX of €13.65M – €31.20M.

Equipment scope this project actually needs
- Aerators / blowers
- Oxygen generation or LOX
- Pumps
- Mechanical filtration (drum filters)
- Biofiltration

- Automatic feeding system
- Feed storage (silos / warehouse)
- Water quality monitoring & alarms
- Backup generator
- Solar for auxiliary loads
- • At this density a power or oxygen failure can cause total livestock loss within hours — full redundancy is mandatory.
- • RAS figures here are preliminary planning estimates, not an engineered design.
Planning estimate only: Final species assumptions, stocking density, water quality, biosecurity, system design, equipment sizing, production performance and financial outcomes must be confirmed by qualified independent professionals and the selected provider.
Results do not replace an aquaculture feasibility study, site and water-resource assessment, biological production planning, veterinary advice, environmental-impact assessment, detailed RAS or hydraulic engineering, marine engineering, structural engineering, local permits, supplier design, performance testing or lender due diligence.
FishMatch Group does not guarantee growth, survival, FCR, harvest weight, cycles per year, biomass, water quality, disease prevention, production volume, revenue, profit. Outputs are not legal, financial, engineering, tax or veterinary advice. Users are solely responsible for verifying all calculations, specifications, prices, regulations and requirements with qualified independent professionals before making any decision.
Supplier and manufacturer listings are provided for research, transparency and discovery only. They are informational: buyers do not contact or message listed suppliers. Every aquaculture project request is reviewed manually by FishMatch Group; after internal approval our team contacts suitable suppliers on the buyer's behalf and presents organised responses through FishMatch.
FishMatch Group is a supplier-neutral sourcing and matching platform. We do not operate farms and do not guarantee survival, FCR, growth, yield, ROI, disease prevention or financing approval. Final system design must be validated by qualified aquaculture engineers, suppliers and aquatic-health professionals.
