Abstract
It has good flavor and appearance, consistent meat content, and can also contribute to improving environmental issues. To provide a method for cultivating sea urchins. [Solution] The aquaculture system 1 to which the sea urchin U aquaculture method of the present invention can be applied uses land-based aquaculture The system can be applied to house the sea urchins U, which are the target of aquaculture, in tank 2. The sea urchins U targeted for cultivation using System 1 are boiled udon noodles that have been boiled at least once. Sea urchins are farmed by feeding them a shortened feed S. This allows for the production of high-quality sea urchins in a short period of time. It is possible to use discarded udon noodles as food for sea urchins, and discarded udon noodles Sea urchins, which are considered a nuisance in the sea due to the problem of coastal barrenness, are being harvested near fishing grounds where they are abundant and used for aquaculture. It can be done this way.
