Abstract
Overgrazing by sea urchins has turned algal beds barren on many coasts of Japan. When sea urchins are removed, the algal beds recover. However, There are problems with the importation of cheaper sea urchins from overseas and labor shortage work against the removal of sea urchins by domestic fishermen. On the other hand, a local market for the excess sea urchins could be developed to expand consumption. Problems remain in increasing the catch of the sea urchins and selling them rapidly, but fishermen producers could increase both the catch and markets gradually.
