Although there has been much talk about cultivating sea urchins by feeding them with vegetable scraps as fodder, until now “cultured sea urchins” have faced various issues such as taste, stable supply of feed, and the time required to improve the harvest.

The aquaculture technology used in “Hagukumu Uni” was established in cooperation with Hokkaido University and other research institutions with strong expertise in fisheries research.

The combined knowledge and know-how gained from our long experience with sea urchins through “Uni Farm®” has created a special advantage that cannot be found anywhere else.

They taste similar to naturally grown ones

Through metabolome analysis, which examines the taste and its components, we have objectively evaluated the taste of cultured sea urchin and reproduced a taste similar to that of natural sea urchin.

Our developed feed makes sea urchins fat quickly.

Feed production technology was established through multivariate analysis of spectra in the near-infrared region. We were able to confirm an improvement of approximately 5.5 times in the yield of fish compared to before the start of aquaculture.

They can be eaten out of season.

By using feed for growing sea urchins, it is now possible to grow sea urchins regardless of the condition of the seaweed beds.

This makes it possible to produce and ship sea urchins regardless of the season.
