Seaweed

　　　　Haimen is located at the southern end of the Yellow Sea, on the north bank of the Yangtze River estuary. The coastal tidal flats here are flat, and the area enjoys a mild climate, nutrient-rich water, and suitable salinity—providing ideal conditions for seaweed cultivation. As a result, Haimen produces large quantities of high-quality laver (Porphyra yezoensis), with over 5,000 standard containers of dried laver exported annually to markets such as Hong Kong, Japan, and Southeast Asia. Laver is highly nutritious, with every 100 grams of dried laver containing 28–35 grams of protein, 48.5 grams of carbohydrates, 200 milligrams of fat, 343 milligrams of calcium, 1 milligram of vitamin C, 5.1 milligrams of niacin, 457 milligrams of phosphorus, 1.23 milligrams of beta-carotene, 2.07 milligrams of riboflavin, and abundant amino acids. Laver also offers preventive and therapeutic benefits for many diseases, especially cardiovascular conditions.
