The Research
• Roe enhancement
• Holding system technology used in
Norway
• Trial One in Japan
- Methodology
• Expectations
• Looking ahead (next steps)
Commercial roe enhancement
Fishing wild urchins
2-3 months

Nofima sea urchin diet:
- Improves taste of roe (more storage cells)
- more consistent quality (condition and colour)
Holding system technology (SeaNest)
• Troms Kråkebolle AS (Tromsø)
(sea urchin farm)
• ScanAqua (Hammerfest)

Trial One
in Utatsu, Japan
Strongylocentrotus nudus
Methodology
• Harvesting
• Roe enhancement
• Quality and market testing
Harvesting
• Harvest 5cm test diameter urchins (2 tonne)
• Using local fishermen and fleet
• Initial assessment (size, gonad index)

Quality and Market testing
Size, colour,
texture, firmness,
taste (umami)
Expectations from Trial One
• Increase in GI per week (example from Norway):
Initial GI
10%
Final GI (2.5 months) 20%
• 20% stocking density
• Feeding every
second week
Expectations from Trial One
Working knowledge of roe enhancement
systems and protocols
Key performance factors (Trial 1)
•
•
•
•
Nofima feed must remain stable (>14oC)
Feed must be palatable to sea urchins
Holding and feed systems must be established
Initial quality of the sea urchins at the site
must be tested
• Quality of roe must be excellent
• Must be economically viable
Next Steps
• Complete Trial 1
• Trial 2
- Based on findings from Trial 1
- High temperature feed (produced in Japan)
- Holding urchins into non-fishing season to see
market response
- Test feed effect on regular sea urchins with
acceptable levels of roe
Looking forward
• Choose expansion sites for 2016 for
commercialization phase with interested
Japan Fisheries in Tohoku
• Conduct similar trials with Ezo Bafun Uni with
interested Japan Fisheries in Hokkaido region
Summary
•
•
•
•
•
•
Trial 1 to begin in 1-2 months in Utatsu
Expect roe enhancement to be successful
Test quality and market acceptability of roe
Continuing trials based on results from Trial 1
Commercialisation in Utatsu
Test roe enhancement in other areas in Japan
and on other sea urchin species
