Nagami Ezo scallop is a geographical indication certification trademark.

Ezo is the old name of the Sakhalin region in ancient China, so the scallops found there are called Ezo scallops and are native to Japan and Korea. It has been introduced into my country, and artificial breeding and multiplication production have been carried out in Dalian Changhai County, Shandong, Liaoning and other northern coastal areas. It is a large cold-water shellfish. Ezo scallops grow slowly and have larger shells, reaching more than 10 cm. The left shell is slightly flat, slightly smaller than the right shell, and is often purple-black. The right shell is more prominent and yellowish white. The front and rear ears are of equal size. There are 15 to 20 radial ribs on the shell surface. Generally, the left shell lies flat on the seabed, and there are no spines on the ribs.

Ezo scallops are distributed on the bottom of the sea with hard bottom and little silt. The natural distribution water depth is 6-60m, and the growth temperature range is 5-20°C. The optimal growth temperature is around 15°C. It grows slowly below 5°C. When it reaches 0°C, the movement slows down sharply and stops; when the water temperature rises to 23°C, Life ability gradually weakens, and movement will soon stop after the temperature exceeds 25°C. Ezo scallops are a high-salt species. The suitable salt range is 24‰-40‰, and the salinity should not be lower than 24‰.

Ezo scallops are an important species of shellfish in recent years. Their adductor muscles have a special protein composition. According to analysis, every 100 grams contains 63.7 grams of protein, 3 grams of fat, 15 grams of sugar, Calcium 47 mg, phosphorus 886 mg, iron 2.9 mg. Ezo scallops are rich in unsaturated fatty acids EPA and DHA. EPA can greatly reduce the formation of thrombus and hardening of blood vessels. DHA can not only promote intellectual development and increase IQ, but also reduce the incidence of Alzheimer's disease. A glycoprotein extracted from scallop adductor muscle has the effect of destroying cancer cells. In addition, scallops also have the functions of nourishing yin and nourishing the kidneys, and have good curative effects on physical weakness, loss of appetite, malnutrition and other diseases.
