　　Lianyungang has been engaged in the artificial cultivation of kelp for over 40 years and is the only kelp-producing area in Jiangsu Province.

　　Kelp belongs to the brown algae phylum and the Laminariaceae family. The algal body is brown, flat, and strap-like. Cultivated kelp is harvested as seedlings in autumn, with individual seedlings clipped onto seeding ropes and placed in the sea for farming. It is then harvested the following summer. Kelp contains various organic substances and 18 types of amino acids, along with 6% sugar. It has high nutritional value and offers functions such as expectorant, anti-nodular, diuretic, prevention of hypertension, arteriosclerosis, and excessive fat. It also serves as an industrial raw material for extracting iodine, sodium alginate, mannitol, and others.
