Uni-nomics Building a sustainable industry by balancing nature, science and market forces - The Research Trials Philip James & Sten Siikavuipio Nofima, NORWAY Norway-Japan Marine Seminar 2014 JUNE 4 2014 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 Sea urchin roe enhancement Roe condition Storage cells Stage IV Stage I Stage II Stage III Reproductive cells Reproductive cells Storage cells Stage I Stage II Stage III Stage IV 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) (sea urchin roe enhancement) www.prakt.com SeaNest system technology (Automated) SeaNest system technology (Manual) 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) Roe enhancement • • • • Holding urchins for 2-3 months 2 x holding systems 2 x densities (20%, 40%) 2 x feed regimes - every week - every second week SeaNest holding system Local holding systemt 1 tonne of Nofima feed in Japan Trial treatments Summary details for Trial One Cage type SeaNest Density 20% 40% Local cage 20% 40% TOTALS Feed Length of trial Number of cages in stack Number of stacks Total number of urchins Total weight of urchins Weekly 2.5 months 6 4 1368 136.8kg Every second week 2.5 months 6 4 1368 136.8kg Weekly 2.5 + 2.5 months 6 4 1368 136.8kg Weekly 2.5 months 6 4 2736 273.6kg Every second week 2.5 months 6 4 2736 273.6kg Weekly 2.5 + 2.5 months 6 4 2736 273.6kg Weekly 2.5 months 3 8 168 16.8kg Every second week 2.5 months 3 8 168 16.8kg Weekly 2.5 + 2.5 months 3 8 168 16.8kg Weekly 2.5 months 3 8 336 33.6kg Every second week 2.5 months 3 8 336 33.6kg Weekly 2.5 + 2.5 months 3 8 336 33.6kg 13824 1382.4kg 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 Acknowledgements • Miyagi University and Kessen Numa Research Institute • Norwegian embassy and Innovation Norway • The fishermen in Utatsu in Miyagi Prefecture Thank you!
