From a global point of view, there are three places where sea cucumbers are the best, namely Bohai Bay in China, Vladivostok in the Soviet Union and Hokkaido in Japan. The sea cucumbers in these three places are rich in meat and nutrition, and they are treasures among sea cucumbers.

The sea cucumbers in Bohai Bay include: Long Island Sea Cucumber, Liaoshen, Weihai Sea Cucumber and Qingdao Sea Cucumber, among which the best is Long Island Sea Cucumber.

Long Island Sea Cucumber, a specialty of Long Island, is commonly known as "the head of the eight treasures of the sea", also known as Shali and Sea Rat. Rich in nutrition, suitable for various people to eat. Long island sea cucumbers grow in the natural environment for 3 to 5 years. In addition to water quality, a very important factor is abundant sea mud. There is no sea mud in many places outside Long Island, or even if there is sea mud, it will never be as rich in nutrition as Long Island sea mud.

The boundary between the Yellow Sea and the Bohai Sea and the junction of the two seas have unique geographical and climatic characteristics, and the sea cucumbers bred are unique and delicious. The water quality of Long Island waters, the source of national first-class water quality, is the national first-class standard, which contains a large number of precious marine biological resources.
