In Japan, mainly found in the Inland Sea more shallows, the crab is an important edible crabs. For more than 10 years, such as Japan, Fukui, Kanagawa, Aichi, Hyogo, Okayama, Hiroshima, Yamaguchi, Ehime, Oita, Fukuoka, Nagasaki, Kumamoto Prefectural Fisheries Experimental Farm and Japan Society of Cultivation and Fisheries Study on the Technology Development of Portunus trituberculatus. In recent years, various counties such as the Cultivated Fisheries Center have used the large-sized sinks for the production of coastal fishery resources, and have now produced nearly 3,000 seedlings of Portunus trituberculatus seedlings due to their improved seed production techniques
