English name: laver, seaweed

Rhodophyta: the general name of Porphyra. Porphyra contains up to 29 ~ 35% of protein, iodine, vitamins and inorganic salts. It tastes delicious and can be used to treat goiter and lower cholesterol. It is an important economic seaweed. Widely distributed all over the world, but mainly distributed in temperate zones. About 70 species have been found. The natural growth of laver is limited, and the output mainly comes from artificial breeding. Porphyra haitanensis, Porphyra yezoensis and Porphyra tender are the main cultured varieties.

Japanese name is laver. Porphyra is a marine red algae. The thallus is composed of a layer of cells embedded in a thin layer of colloid, which is dark brown, red or purple. The sexual reproductive structure is at the edge of the thallus. It is distributed in the northern and southern hemispheres, grows at the high tide line of intertidal zone, and grows best in nitrogen-rich waters (such as near the outlet of sewage pipes). After harvesting and drying, it can be used as food, and its consumption exceeds that of other algae. Artificial farming is an important food in eastern countries. It can be used as the main ingredient of soup, other food and meat seasoning. In the British Isles, laver is baked on bread and tastes like oysters.
