The most delicious hairtail species in China is probably the recognized Zhoushan hairtail.
There are two main places in China that produce hairtail: the East China Sea and the South China Sea. In addition, hairtail is also produced in the Bohai Sea and Yellow Sea in the north, but the production is not as high as in the East China Sea and the South China Sea.
Among them, the Zhoushan hairtail produced in the East China Sea can be regarded as the most delicious hairtail in the country. Zhoushan hairtail is one of the first batch of seafood with geographical indication certification trademark in the country. It is very popular at home and abroad, and is even known as "the most delicious hairtail in the world".
1. From the appearance
Zhoushan Hairtail:
Small and narrow, with body width ranging from 4cm to 7cm and length ranging from 40cm to 60cm. The dorsal fin is small, the eyes are usually black, there are no ridges on the back, and the scales fall off easily.
Other hairtail fish:
Relatively large, with a body width of 6cm~10cm and a body length of about 1 meter. The dorsal fin is larger, some eyes are green, and the scales are not easy to fall off.
2. Growth environment
Zhoushan hairtail fish:
The sea area of ??Zhoushan fishery ranges from 29°30' to 31°00' north latitude and west of 125° east longitude. There are four distinct seasons all year round, with no severe cold in winter and no scorching heat in summer. The annual average land temperature is 16.4°, and the average ocean water temperature is 18°. It is the golden section climate zone of the Northern Hemisphere.
The water quality resources here are located at the estuaries of the Yangtze River, Qiantang River, and Yongjiang River. It is the intersection of river water and seawater and the intersection of the Jiangsu and Zhejiang coasts, the warm current of the Taiwan Strait, and the cold current of the Yellow Sea. It is a low-salinity sea area along the coast of my country. , the annual average salinity of seawater is 20.56‰.
And the Zhoushan Archipelago has 1,339 islands, making it the largest archipelago off the coast of China. The currents between the island and the sea intersect rapidly, the waters are turbid, the bait is rich, the seabed is flat, and the seabed is wide. The depth of the seawater is generally 20-40 meters, the sunlight can directly shine on the seabed, and the photosynthesis of organisms is strong.
Other hairtails:
It is widely distributed, mainly distributed in the Western Pacific and Indian Ocean, but does not have such a unique geographical environment as the Zhoushan hairtail.
3. Nutritional value
Zhoushan hairtail:
In addition to the silvery white and tender skin of other hairtails, rich protein and high nutritional value, it also contains hairtail from other fisheries. No DHA ingredient.
The vitamin A contained in the body is an important anti-cancer substance.
The scales and silver-white grease layer all over the body also contain an anti-cancer ingredient, 6-thioguanine, which is useful in the auxiliary treatment of leukemia, gastric cancer, lymphoma, etc.
It is rich in magnesium, which has a good protective effect on the cardiovascular system and is helpful in preventing cardiovascular diseases such as hypertension and myocardial infarction.
The characteristic of Zhoushan hairtail is that its meat is particularly tender and firm. Because the sea area where it grows is at the estuaries of the Yangtze River, Qiantang River, and Yongjiang River, the salt concentration in the sea is relatively low. Moreover, Zhoushan hairtail is in a cold water zone, so it is small in size, grows delicately, and tastes extremely tender with a sweet aftertaste.
The South China Sea hairtail is in a hot water bottle. It grows quickly and is large, but the meat is looser and rougher, and has large bones.
From the appearance point of view, Zhoushan hairtail fish has the characteristics of "three small and one thick": small size, small eyes, small head, and narrow and thick body.
Zhoushan people also have a saying: Zhoushan hairtail is not good-looking, but the good-looking hairtail is not Zhoushan hairtail. This is because Zhoushan fishermen mostly use radar nets and trawl nets when fishing. In the process, crabs, fish and shrimps will be mixed in, and they will inevitably destroy the skin of the hairtail when they struggle.
Finally, I would like to give you a little suggestion. If you buy Zhoushan hairtail, you can try steaming it. The meat is delicate, delicious and not fishy, ??with a unique flavor and very delicious!
