How to Plan a Commercial Shrimp Farm
A structured planning framework for semi-intensive, intensive-lined, biofloc and indoor RAS shrimp projects — from site qualification to commissioning.
Executive summary
- Commercial shrimp farming viability is decided by site water quality, biosecurity and market access — not by equipment brand selection.
- System intensity (semi-intensive ponds, lined intensive ponds, biofloc, indoor RAS) should be selected against land cost, energy tariff and target market price, in that order.
- Typical CAPEX ranges from USD 25,000/ha for aerated semi-intensive ponds to over USD 400,000/ha for indoor super-intensive systems.
- Two-phase nursery systems normally raise annual cycles from two to three and materially improve survival — one of the highest-return planning decisions.
- Feed and post-larvae quality together represent 55–75% of operating cost; procurement planning should begin before equipment specification.
Project objectives
- Define target annual production in tonnes, harvest size and market channel (domestic fresh, export frozen, value-added) before selecting a production system.
- Establish a defensible cost of production per kilogram and compare it to realistic farm-gate prices in the target market.
- Secure a biosecure, permitted site with reliable water source, salinity and discharge capacity.
- Build a phased development plan that allows expansion without redesigning core infrastructure.
Planning considerations
Site qualification and water resources
Site quality determines the ceiling of every shrimp project. Assess water source reliability, salinity range across seasons, soil permeability and acid-sulphate risk, elevation for gravity drainage, and legal discharge routes before committing capital.
For inland and indoor projects, verify groundwater salinity and mineral profile (calcium, magnesium, potassium ratios) — remineralisation cost is often underestimated and can shift operating economics by USD 0.20–0.50 per kilogram.
- Twelve months of salinity, temperature and turbidity data where available
- Soil survey: permeability, pH, acid-sulphate potential
- Intake and effluent permitting pathway confirmed in writing
- Distance to processing, ice supply and export gateway
Selecting production intensity
Production intensity should be chosen against three constraints: land availability and cost, electricity tariff and reliability, and achievable market price. High-intensity systems only outperform when land is expensive and power is stable and affordable.
Semi-intensive aerated ponds deliver 4–10 t/ha/yr at moderate capital intensity. Intensive HDPE-lined ponds reach 15–30 t/ha/yr. Biofloc and covered raceways reach 25–60 t/ha/yr with significantly higher operational discipline. Indoor RAS shrimp can exceed 50 t/ha/yr but requires the highest technical capability and energy input.
Biosecurity design
Disease is the dominant cause of commercial failure in shrimp farming. Biosecurity must be designed into the layout — reservoir and settling ponds, separated clean and dirty traffic routes, disinfection points, bird and crab exclusion, and dedicated equipment per production unit.
Specify specific-pathogen-free (SPF) post-larvae sourcing, PCR screening protocols and a written health management plan. Lenders and insurers increasingly require both.
Technical requirements
- Aeration sized on standing biomass: approximately 1 HP per 400–600 kg for intensive systems
- Water exchange or treatment strategy defined per phase (nursery, grow-out, pre-harvest)
- Alkalinity, mineral and pH buffering programme appropriate to source water
- Two-phase nursery raceways with independent heating where seasonal temperature drops apply
- Sludge and effluent treatment sized for permitted discharge limits
- Monitoring: dissolved oxygen, temperature, pH, salinity with alarm and backup logging
Infrastructure requirements
- Primary and standby power with automatic transfer; aeration failure tolerance under 15 minutes
- Pumping station with redundancy, screened intake and reservoir buffer volume
- Feed storage protected from humidity, sized for at least four weeks of consumption
- Harvest, chilling and ice capacity matched to peak single-pond harvest volume
- Access roads rated for refrigerated truck loading in all weather
- Laboratory space for water chemistry and basic health diagnostics
Budget considerations
Indicative shares of total project cost. Ranges are supplier-neutral planning references, not quotations.
| Cost block | Indicative share | Planning note |
|---|---|---|
| Land, earthworks and pond construction | 25–40% of CAPEX | Dominant in pond systems; HDPE lining typically USD 3–7/m² installed. |
| Aeration and circulation | 10–18% | Sized on biomass, not pond area. |
| Pumping, intake and effluent | 6–12% | Includes permitting-driven treatment. |
| Nursery and hatchery stage | 5–12% | Improves cycles per year and survival. |
| Power, buildings and cold chain | 10–20% | Generators, transformers, harvest chilling. |
| Engineering, commissioning and contingency | 10–15% | Never below 10% in a bankable plan. |

Common mistakes
- Selecting production intensity before validating energy tariff and reliability
- Sizing aeration on pond surface area instead of standing biomass
- Omitting a nursery phase and losing a full production cycle each year
- Underestimating remineralisation cost for low-salinity or inland water
- Building full design capacity in one phase instead of proving the first module
- No contingency line, which weakens the project in lender review
Project preparation checklist
- Twelve-month water quality dataset or nearest credible proxy
- Written permitting pathway for intake and discharge
- Production model with FCR, survival and cycles per year clearly stated
- CAPEX and OPEX model with sensitivity on feed price and energy tariff
- Biosecurity plan and PL sourcing strategy
- Harvest, chilling and route-to-market plan
- Technical specification package ready for supplier-neutral RFQ
