Aquaculture Procurement: Species, Systems, Equipment and Lifecycle Cost
Short answer: buy in the right order. Choose species and market first, then site and water, then the farming system, then the equipment scope. Only then ask suppliers to price the same written specification, and compare offers on the cost of building and running the farm over its life, not on purchase price alone.

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.
1. Which species and market are you buying for?
Species decides water temperature, salinity, stocking density, feed, growth time and the price buyers pay. Confirm who will buy your harvest, in what form and size, before choosing a system. Water source and climate at your site then narrow which species are realistic.
2. Which farming system fits your project?
| System | Usually fits | Watch for |
|---|---|---|
| RAS (recirculating) | Land-based sites with limited water, high-value species, control over temperature and biosecurity | Highest power and skills need; backup power and oxygen are critical |
| Ponds | Available land and water, warm climate, species such as shrimp or tilapia | Weather and water-quality swings; aeration and water exchange drive running cost |
| Cages / net pens | Sheltered sea or lake sites with permits and good water exchange | Site licensing, storms, moorings and environmental monitoring |
| Flow-through | Reliable cold water source, for example trout | Water rights and discharge rules |
3. What equipment goes into the specification?
- Tanks, ponds or cages and their civil works
- Pumps, piping and water treatment (mechanical and biological filtration, UV or ozone, degassing)
- Aeration and oxygen supply
- Heating, chilling and heat exchange
- Monitoring, controls and alarms
- Feeding systems
- Backup power
- Hatchery or nursery units, if you produce your own juveniles
- Harvest, processing and cold chain
Decide whether you buy one turnkey package or separate packages; either way, write who is responsible for each interface between them.
4. How do you compare lifecycle cost, not just price?
Lifecycle cost = building cost + running costs over the planned life + replacements + financing. Ask every supplier for the same items below, in writing.
| Cost item | Ask each supplier for |
|---|---|
| Building cost (CAPEX) | Itemised scope, exclusions, civil works, delivery, installation and commissioning |
| Energy | Running kW at your duty point and operating hours |
| Feed and juveniles | Your feed plan and supply source; supplier assumptions in writing |
| Labour and training | Staff numbers and skills the system needs; training included |
| Oxygen and consumables | Use per kg produced and delivered price |
| Maintenance and spare parts | Service intervals, spare-parts list and prices, local service response |
| Replacements | Expected life of pumps, blowers, membranes, UV lamps and sensors |
| Financing and working capital | Cash needed until first harvest sales |
5. Where do sourcing platforms fit?
Marketplaces and supplier directories help you discover options, including manufacturers in China and Asia. They do not replace your own project brief and decision criteria. Our sourcing article explains what platforms solve, what they don't, and a checklist to finish before you contact suppliers.
