The scallops of ZhangziDao are abnormal again, aren't they...
Zhangzidao's pre-loss in 2017 exceeded 500 million yuan, citing "abnormal stocks of bottom-sown Ezo scallops in some areas".
This is not the first time that everyone has ridiculed "the scallops of Zhangzidao have run away". In 2014, Zhangzidao issued an announcement that due to the abnormal cold water mass in the North Yellow Sea in decades, more than 1 million mu of Ezo scallops that were about to enter the harvest period were harvested, from a forecast profit to a loss of about 800 million yuan. Natural disasters lead to huge losses, it is natural, it is really...

Scallops run fast!
Don't laugh, scallops can move 50 cm per second! I ask you, can you still run in 10 seconds in 50 meters?
What do scallops run on? leg?
After prying open the shell, you can see the structural basis of the scallops that can escape quickly. In its soft tissue structure, the most conspicuous is the milky white cylindrical closed shell muscle in the center, which is dried and sold in the market. When the closed shell muscle contracts, the two shells are tightly closed. In fact, bivalves have two anterior and posterior closed shell muscles, but the anterior closed shell muscle of scallops disappears, leaving only a particularly developed posterior closed shell muscle.
The internal structure of the scallops
Two thousand years ago, in addition to the closed shell muscle, there was Aphrodite.
When movement is required, the posterior closed shell muscle can quickly and repeatedly contract and relax to absorb water into the shell, while the mantle membrane at the edge of the shell closes so that the water can only eject from the hinges of the two shells, so that the scallops can swim one by one like Pac-Man. Because of this structure, scallops are the only group of shellfish that have migratory behavior.
biu biu biu, do you still want to eat me?
Such a delicious thing just ran away? distressed
The developed closed shell muscle is the most delicious part of the scallop body, a large number of amino acids and nucleotides in the cells bring it plenty of fresh sweetness, excess spices and excessive cooking will damage its delicious taste, simply frying, steaming or directly making sashimi raw is the best.

Dried scallops concentrate the umami substances, and then soak the soup like natural MSG. In fact, there is more than one source of dried scallops, including many species of shellfish in the scallop family and the family Jiangjue, but according to the production area and production, many of the dried shellfish I saw as a child should come from the ctenophore scallops Chammys farreri.
However, when eating, do not only eat the closed shell muscle and throw away the others, the structure around the closed shell muscle can also be eaten, such as the coat film (skirt) wrapped in soft tissue, the taste and texture are good. Orange (female) or white (male) reproductive glands and black digestive glands are more likely to be enriched with algal toxins and heavy metal contaminants, although it can be eaten, but it is best to assess the risk of eating with caution.

There are many edible species in the scallop family. Zhangzidao is the introduction of Ezo scallops (Patinopecten yessoensis), formerly common in the north is the Ctenos farreri (Chlamys farreri), China's coastal distribution of long ribs Sun Moon Shell Amusium pleuronectes, the magnificent ctenophore scallops Chlamys nobilis, the introduction of bay scallops Argopecten irradians and purple scallops and so on.
Originating in the waters near Japan, the Ezo scallop is the largest of the common scallops, the shell diameter can be 20 cm, called "sail shell" in Japanese, which can be seen to be large, and a small number of Ezo scallops because of genetic mutations make the carotenoids accumulated in closed shell muscle cells orange-red.

Ctenophores scallops are shaped like folding fans, with signature radial patterns on the surface of the shell. The shape of the two shells of the ctenophore scallop is slightly different, generally speaking, the left shell is flat and the right shell is slightly bulging, when inhabiting the seabed, it is generally a flat left shell on the top, and the hinge of the two shells has an ear in front of and behind it, and the name of the ctenophore scallop is because its right shell has fine ctenophores and foot filament holes in the front ear.

The long rib sun and moon shell is called the Asian sun and moon clam in Taiwan, and the sun and moon fish in Hong Kong, the word sun and moon is derived from the different colors of its left and right shells, the left shell is brownish red and the right shell is white.

The shells of the magnificent ctenophores are available in orange, purple, brown and other colors. Bay scallops are native to the Atlantic Ocean, smaller than ctenophore scallops, and the diameter of the shell is generally five or six centimeters. Native to the South Pacific, purple scallops are the main farmed shellfish in the Americas, with purple shells and large large constrictor muscles.

The problem is that many of these scallops can be hybridized with each other, and many of the scallops seen in the market are hybrids, which is more troublesome to identify - fortunately, as long as the scallops are delicious!
Even more demonic is more than a hundred eyes
If you look closely at the live scallops, you can also find that there are dark dots on the mantle membrane at the edge of the shell, these are its eyes, which can have one or two hundred. Although it is impossible to do 360 ° without dead angles, it is also considerable to be able to cover an azimuth angle of about 250 °.
Look me in the eye
Each eye has a retina and lens, but the structure is simple, and it can only feel the changes of light and dark light and shadow and cannot distinguish the shape, which helps scallops escape danger when predators such as starfish invade. The imaging principle of the eye is similar to that of a reflective telescope, in that the light is concentrated by a concave mirror and imaged in front of/above the mirror.

It is said that before the zhangzidao bottom sowed scallops, the islanders said, "What if these Ezo scallops grow up and wander around?"
It seems that scallops will wander this thing, the islanders know, you know, only the management does not know...
