Mediterranean cage farming and inland trout projects in Spain.
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.
- Sea bass and sea bream cages
- Trout raceways
- Emerging RAS
- Aeration and pumping
- Feed efficiency
- Offshore expansion
Indicative project plan
A 750 t/year marine fish (sea bass / bream / barramundi) project in cage / offshore cage (Spain) needs roughly 31,849 m³, 1,200 t of feed per year, 0 kW of aeration and an indicative CAPEX of €3.30M – €9.07M.

- Feed barge / service craft
- Automatic feeding system
- Feed storage (silos / warehouse)
- Water quality monitoring & alarms
- Solar for auxiliary loads
- • At this density a power or oxygen failure can cause total livestock loss within hours — full redundancy is mandatory.
- • Cage feasibility depends on depth, currents, exposure and access — a professional site assessment is required.
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. FishMatch Group does not provide automatic buyer-supplier introductions. Every aquaculture project request is reviewed manually by David / FishMatch Group, and supplier introductions are made only after internal approval.
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.
