In order to change the current situation in which we are forced to dispose of sea urchins that are too thin due to lack of food due to isoyake problem, Kitasanriku Factory has established its own “sea urchin regenerative aquaculture” technology, which provides high quality taste, good harvest, speed of growth, processing and sales, and provides total support to businesses that are in the same kind of trouble. We also provide total support for businesses troubled by similar circumstances, from the start of the aquaculture business to shipping and sales channels.
