Roughly 30–40% of Somali fish and dairy production is lost between harvest and final sale, almost entirely because the cold chain breaks somewhere. This is a primer on what a working cold chain actually looks like and where most producers go wrong.
The five links in a cold chain
- Capture/harvest cooling — getting product from body temperature to 4°C within 90 minutes
- First-mile transport — insulated truck or iced container from landing site to processing
- Processing & storage — chiller (0–4°C) or freezer (-18°C) with backup power
- Distribution — reefer container or refrigerated truck to port or wholesaler
- Last-mile — buyer's cold room
A break in any link wastes the entire chain. This is why a $200 spoiled-fish loss on a single boat can cascade into $20,000 in rejected shipments downstream.
Backup power is the whole game
"If your generator can't kick in within 30 seconds, you don't have a cold chain. You have a refrigerator that sometimes works." — Marine engineer, Bosaso
Practical setup for a 20-tonne fish processing plant:
| Component | Capacity | Approx. cost (USD) |
|---|---|---|
| Solar PV array | 60 kWp | 48,000 |
| Battery storage (Li-ion) | 120 kWh | 38,000 |
| Diesel generator (auto-start) | 80 kVA | 22,000 |
| Chiller room (40 m²) | 4°C | 35,000 |
| Blast freezer (10 m²) | -30°C | 28,000 |
Total: ~$171,000. Payback under current fish prices: 18–26 months if you're processing 2 tonnes/day.
The mistakes that kill projects
- Buying a generator without an auto-transfer switch
- Sizing the chiller for current volume rather than 18-month projected volume
- Skipping the data logger — without temperature records you can't claim insurance and you can't sell to GCC retailers
- Putting the compressor where it gets direct sun (cuts efficiency by 25%)
Where to start if you have $40,000 to spend
A "minimum viable cold chain" for an artisan fisheries cooperative:
- 1× insulated landing-site container with ice machine ($14k)
- 1× 8-tonne refrigerated pickup truck (used, $18k)
- 1× small chiller room at the cooperative HQ ($8k)
This won't get you to EU export standards, but it will cut post-harvest loss from ~35% to ~12%, which alone usually pays back the investment in a single fishing season.
