Eel
Eel is farmed exclusively from wild-caught glass eels (larvae). Grown in freshwater RAS or intensive ponds, primarily for the Japanese, Korean and European unagi / kabayaki markets.
Which system fits Eel?
European eel farming is almost entirely RAS-based.
Intensive pond production in East Asia.
Growing-on systems.
Older systems, declining.
Not used.
Closed-cycle hatchery is not commercially available — depends on wild glass eels.
Scope, layout & utilities
- Cycle: 12–36 months from glass eel to 200 g – 1 kg market size.
- Optimal temperature 25–28°C.
- Requires stable warm water and high-quality feed.
- Utility planning: heat, oxygen, robust biofiltration.
- Sustainability: glass eel supply is subject to CITES restrictions.

Head-to-head trade-offs
| Metric | RAS | Earthen / Lined Pond |
|---|---|---|
| CAPEX per kg/yr | High | Low – Medium |
| Water use | Very low (95%+ recycled) | High (exchange or evaporation) |
| Land footprint | Small, indoor | Large, outdoor |
| Biosecurity | Excellent (closed loop) | Weather / disease exposure |
| Year-round production | Yes, climate independent | Seasonal in many climates |
| Skill requirement | High — engineering + biology | Medium — biology-led |
| Best fit | High-value markets, land-constrained sites | Low-cost regions, large-scale commodity output |
| Metric | Indoor | Outdoor |
|---|---|---|
| Climate control | Full | None |
| Energy cost | Higher | Lower |
| Predation & birds | None | Requires netting |
| Consistency | Very consistent harvests | Weather-dependent |
| CAPEX | Higher (building + HVAC) | Lower |
Major CAPEX & OPEX drivers
- RAS tanks + biofiltration
- Heat / insulation
- Water treatment
- Glass eels (very high, variable)
- Feed
- Energy
- Labor
Constrained by glass eel supply and CITES quotas.
Heat and pumps dominate; RAS insulation is critical.
Checklist before requesting quotations
- Glass eel supply and quota compliance.
- RAS specification (biofilter, temperature, DO).
- Heat recovery for OPEX efficiency.
- Cold chain and premium processing.
