Scallop shells resemble scallops, hence the name. The white muscle inside the shell is the closed shell muscle, which is responsible for the opening and closing of the scallops, also called the shell pillar, and the flesh is delicate, delicious and nutritious. Dried shells are dried and listed as one of the eight treasures.
The scallops look well-behaved, but they are strong swimmers underwater. The swimming style is very soul-sucking!

Bay scallops are hermaphrodites, a strange species that is both a father and a mother.

Ezo scallops are large, with a shell length of 80-120 mm, and as large as 200 mm, it looks very attractive. Ezo scallops are the "stars" of the moment, more than 20 yuan per kilogram on the market, and 7-10 yuan per à la carte garlic scallops in restaurants, and the sales are good.

At present, The production of scallops in China mainly comes from aquaculture, and the harvesting of wild scallops is very small. Scallop culture methods include offshore cage culture and bottom sowing culture.
In Changhai County, Ezo scallops are cultured in hanging cages, also known as "one-aged scallops", as the name suggests, Ezo scallops that have been farmed in hanging cages for more than one year.
Bottom-sown farmed Ezo scallops, commonly known as "bottom-sown scallops", they grow freely on the seabed, harvested and shipped after 3-5 years, with a thick shell, is the most expensive scallop, mainly supplied to high-end catering venues in the country.

The main food of scallops is organic detritus, plankton suspended in seawater. Therefore, there is no need for artificial bait in the scallop farming process, which is a naturally growing green high-quality marine aquatic product.
<h1 class="pgc-h-arrow-right" > How to eat? </h1>
Scallops are filter-feeding organisms, and if the scallop's growing environment is contaminated, or if the algae it ingests are toxic, the scallop's digestive glands contain toxins and heavy metals in addition to excrement and sediment.
Therefore, in a nutshell: gonads, closed shell muscles, and mantle membranes can be eaten; digestive glands and gills are not recommended. Of course, there are also many people who eat cooked scallops and swallow them with ginger, rice, garlic and soy sauce.
There are many ways to eat scallops, steamed scallops with garlic vermicelli, fried scallop eggs, scallop skewers, tut, are the favorite of the editor!
