Because northern hairtail grows in low-temperature waters, its growth cycle is longer and its meat quality is more delicate, while southern hairtail grows faster, its meat quality is rougher and its taste is quite different.
Therefore, hairtail is mainly produced in the western Pacific Ocean and the Indian Ocean, and distributed in the Yellow Sea, the East China Sea and the Bohai Sea in China until the South China Sea. Together with large yellow croaker, small yellow croaker and squid, it is also called China's four seas fresh.
Hairtail along the coast of China can be divided into two categories: south and north. The hairtail in the north is bigger than that in the south. It overwinters in the south of the Yellow Sea in spring and swims to the Bohai Sea, forming a spring fish season, and returns to the wintering area in autumn, forming an autumn fish season. The southern hairtail moves north and south along the western edge of the East China Sea every year according to different seasons, and migrates to the north in spring and to the south in winter. Hairtail in the East China Sea can be divided into spring and winter. Hairtail spawns for a long time, mainly in April-June, followed by 9-165438+1October, spawning amount is 25000-35000, and the suitable water temperature for spawning is 17℃ ~ 23℃.
Domestic hairtail is mostly 4 ~ 7 cm wide and 40 ~ 60 cm long, and the silver skin outside is mostly incomplete. Domestic hairtail fish is tender, which has no "firewood" feeling and tastes delicious.
Imported hairtail growing in tropical areas is usually huge, ranging from 6 to 10 cm in width to about 1 m in length. Because the imported hairtail is frozen immediately after fishing, the silver skin is intact. Imported hairtail fish is hard, although there are more fish, but the taste is not enough. Because the skin of imported hairtail is thick, it is not easy to stick to the pot when frying.
When distinguishing, body shape is a difference. In addition, the domestic fishtail vertebra is small, while the imported fishtail vertebra is large.
In fact, domestic hairtail represents delicious food. In the East China Sea, you can actually catch so-called imported hairtail.
Dalian and Zhoushan, these are two signboards of hairtail in China. In order to get a good price, fishmongers pass imported hairtail off as domestic hairtail. Obviously, they have understood people's preference for domestic hairtail. At present, more than 70% of hairtail and yellow croaker named after Dalian and Zhoushan are Gui Li. Its appearance is bright, and its price is 30% lower than that of domestic hairtail. However, the number of hairtail and yellow croaker in China is very small every year, decreasing by 10% every year. Therefore, imported fish is very popular in the domestic market.
The most famous hairtail in China is Zhoushan Fishing Ground, which is located in the east of Hangzhou Bay, the northeast of Zhejiang Province and the southeast of the Yangtze River estuary, with an area of about 53,000 square kilometers. It is a traditional operation area for fishermen in Zhejiang, Jiangsu, Fujian, Shanghai and Taiwan Province provinces. The four major economic fish are Pseudosciaena crocea, Pseudosciaena crocea, hairtail and cuttlefish.
Zhoushan is rich in hairtail, which is called the first hairtail in the world because of its season and sea area. Zhoushan hairtail has no fishy smell, and its meat is tender, plump and thick, which is deeply loved by diners all over the world.
