Product description ※Please note that product information is not in full comprehensive meaning because of the machine translation.

Fisheries Research on commercial sea urchins has been conducted mainly since the 1960 s with the aim of developing the fisheries industry. As a result, many results have been obtained toward the development of technologies for breeding and culturing resources in natural areas and for processing and preservation as foods. As a result, many results have been obtained for the world's first.
However, due to the influence of recent warming and acidification of the sea, the number of sea urchins has been decreasing.
On the other hand, the price of sea urchins as foods has been rising rapidly with the increase of demands worldwide, and there is a need for an increase in production and a stable supply of sea urchins by establishing new culture technologies.
The results of research on biology, ecology and water obstetrics supporting the stable production technology of Japanese sea urchins through fisheries, aquaculture and processing and distribution are summarized.
