Zhangzidao sea cucumber is produced in the sea area of Zhangzidao, located at the edge of the cold water of the Yellow Sea, which not only enhances the exchange ability and self-purification ability of seawater, but also makes sea cucumber stronger in the turbulent current. The perennial low temperature makes the nutrient deposition of sea cucumber more sufficient, and the vertical distribution of salinity makes the nutrient intake more abundant. Therefore, the sea cucumber produced in Zhangzidao is a pure natural nourishing product.
