Fish Farm Equipment Upgrades for Existing Farms: Cost Drivers and a Realistic ROI Model
How operating fish and shrimp farms price equipment upgrades: what drives installed cost, a transparent ROI and payback model, a base vs downside test, and new vs refurbished vs used options.
Retrofit or Replace? A Decision Framework for Existing Fish and Shrimp Farm Equipment
How existing farms decide whether to repair, retrofit or replace aerators, pumps, filters, blowers and RAS components: condition checks, lifecycle cost, risk and a comparison table.
How to Expand a RAS Without Disrupting Current Production
Practical plan for adding tanks, biofilter or treatment capacity to an operating recirculating aquaculture system: shared-loop checks, isolation, tie-ins, biofilter start-up, biosecurity and commissioning.
Capacity Bottleneck Audit for Existing Fish and Shrimp Farms: Oxygen, Water, Feed, Power and People
A step-by-step audit to find what is really limiting output on an existing farm before buying equipment: data to collect, the order to check systems, a bottleneck table and how to rank upgrades.
Aquaculture planning benchmarks
| Figure | Value | Context |
|---|---|---|
| CAPEX — RAS | USD 9,000–14,000 per tonne/yr | Global baseline before country cost factor. |
| CAPEX — Ponds | USD 1,800–4,000 per tonne/yr | Lined or earthen ponds, excluding land. |
| CAPEX — Cages | USD 2,500–5,500 per tonne/yr | Cages, moorings, nets and service equipment. |
| CAPEX — Flow-through | USD 4,000–7,000 per tonne/yr | Raceways and water intake works. |
| Energy use | RAS ~6 kWh/kg; ponds ~1.2; flow-through ~1.5; cages ~0.3 | Per kg of fish produced. |
| Typical FCR | Trout 1.1; salmon 1.2; shrimp 1.4; tilapia 1.6; carp 1.8 | kg feed per kg growth; varies with feed and management. |
| Farm size where FishMatch reviews projects | From ~USD 250,000 total project value | Commercial fish and shrimp projects. |
