Striped fish are called knife fish in the Qingdao area. Of course, this knifefish is not the same as the Japanese saury knifefish. The reason why the striped fish is called knife fish, according to the elders, seems to be influenced by Japanese culture. Nearly a century ago, Qingdao was occupied by the Japanese for a period of time, and it is said that at that time, the striped fish in Qingdao was called knife fish. However, the shape of the fish does resemble a knife, which is why Qingdao people can accept this name.
Nowadays, it is the golden season of Qingdao's local knifefish. Recently, local knifefish have often been seen in the market, and the local knifefish weighing about one kilogram in four fingers is more expensive than one kilogram. The meat of the local knife fish is delicate and mellow in taste. It can be said that a mouthful of local knife fish can not be forgotten for a long time.
This newspaper once published a food article by shan Yanchun, a reporter of this newspaper, specifically analyzing the difference between local knife fish and foreign knife fish. An excerpt is provided below.

During the fishing moratorium, the market is in large numbers of frozen marine fish, of which striped fish is one of the most important species. With fish, Qingdao people are generally called knife fish, but in recent years, more and more people call it belt fish, we collectively call it belt fish. Looking around the market, you will find that the price of fish with fish ranges from 15 yuan to hundreds of yuan per catty, and the varieties of fish seem to have some differences in appearance. What are the reasons for this?

There are four major production areas of the world's striped fish
Wang Yingeng, an expert in the fish room of Qingdao Yellow Sea Fisheries Research Institute, said that the striped fish are widely distributed in the world, and the warm waters of the world's oceans are distributed, but they are mainly concentrated in four regions. The first area is china's East China Sea and South China Sea, the main fishing countries are China, North Korea, South Korea and Japan. The second region is in Southeast Asia, where the main fishing countries are Myanmar, Thailand, Malaysia and Indonesia. The third region is in the northern part of the Indian Ocean, with the main fishing countries being India, Pakistan and Oman. The fourth region is off the coast of West Africa in the Atlantic Ocean, where the main fishing countries are Morocco, Senegal and Ghana.
Among the four fishing areas, the best quality and the largest catch of the fish are china's East China Sea and South China Sea.
Four species of striped fish are common in Qingdao markets
Wang Yingeng introduced that the striped fish belong to the order Perciformes, and the striped fish family is divided into 9 genera and 44 species. There are four common types of white-banded fish, short-striped fish, South Sea striped fish and African striped fish common in Qingdao market.
White-banded fish, also known as the striped fish, also known as high-finned striped fish, tooth belt or knifefish, is relatively large, the tail is slender like a whip, the body is silvery-white, the dorsal fin and pectoral fin are pale white, and the body length can reach 2.34 meters. White-belted fish are distributed in the warm waters of the world's oceans and along the coast of China, but concentrated in the East China Sea, and Zhoushan Fishery is the world's largest white-belt fish production area.
Short-banded fish is also known as the Chinese short-tailed banded fish, Qiong-banded fish, the body is slender and flattened, the dorsal fin is white, the body length can reach 0.55 meters, mainly distributed in the waters around China's Hainan Province. South China Sea belt fish are relatively large, the tail is slender, there is no ventral fin and caudal fin, generally inhabit the coast, mainly distributed in the south of the East China Sea and the South China Sea.
West African forktail fish are mainly distributed in the waters off the coast of West Africa, living in waters of 20 to 500 meters, the body of the West African forktail fish is silvery, the gill cover is black, and the body length can reach 43 cm. The striped fish imported from West Africa in China are mainly West African forktail striped fish, which are mainly caught by the China Aquatic Products Corporation and other private Chinese distant-water fisheries companies in west African waters and transported back to China.
Qingdao striped fish belong to the species of white-banded fish The reporter learned that Zhoushan Fishery is the largest fishing ground in China, and East Sea striped fish are produced around. The East Sea belt fish moves north-south along the western edge of the East China Sea every year according to the season, reproductive migration to the north in the spring, overwintering migration to the south in winter, and the East Sea belt fish have spring floods and winter floods.
The local striped fish species in Qingdao are white-banded fish like the East China Sea striped fish, but they are larger. Qingdao striped fish overwinter in the southern Yellow Sea, swim to the northern Yellow Sea and the Bohai Sea in the spring to spawn, forming a spring fish flood; in the autumn, the group returns to the southern Yellow Sea to overwinter to form an autumn fish flood. That is to say, the belt fish from the south of the Yellow Sea to the north form the main force of the Qingdao belt fish, and the belt fish that return to the East China Sea and the northern part of the South China Sea from the south are called the East Sea Belt Fish.
Wang Yingeng introduced that Qingdao's local striped fish and Zhoushan fishery's striped fish are the same species, but the sea temperature in the sea around Qingdao is lower, the striped fish grows slowly, and the taste of the striped fish produced is also better. In the market, knowledgeable citizens will feel excited to be able to buy local fish in Qingdao. Why? Due to the overfishing in previous years, qingdao's local striped fish production is very small, it is difficult to see Qingdao's local striped fish in the market. In recent years, due to the policy of fishing moratorium in the off-season, the ecology of the northern yellow sea area has gradually recovered, and the market can gradually see the figure of Qingdao's local knifefish.
Qingdao Dongjie Aquatic Products Company has been fishing and selling seafood in Qingdao for many years and has full say in Qingdao's fish market. Zhao Yueyang of Dongjie Aquatic Products Company told reporters that a few years ago, their fishing boat could not hit a few local fish at a time, and before they got off the boat, they were booked by the hotel, and the market could not buy local fish. Now, each time the fishing boats return, they can bring back hundreds of pounds of local striped fish, and in addition to supplying some high-end hotels, they can also have a few frozen in case of emergency.
Zhao Yueyang told reporters that the price of fish in the market now ranges from more than ten yuan to hundreds of yuan per kilogram. The wholesale price of striped fish from Africa is less than ten yuan per kilogram, the market retail price is 15-20 yuan, the retail price of East Sea striped fish is 20-40 yuan, and the retail price of Qingdao local striped fish is at least 100 yuan per kilogram according to the size.
Why is the price difference between the price of fish so much? In addition to the tender and delicious taste of qingdao's local fish, the small amount is the main reason. Local fish should be eaten with innovation The usual way to eat the striped fish we usually eat, the general practice is to fry and eat. However, Qingdao's local fish eating like this is a bit of a violent thing.
Once, I had a dinner party with Mr. Yin Yueming, the chairman of Qingdao Old Boatman Hotel, and served a large local fish with steaming techniques. Diners here were overwhelmed by the tenderness of the local fish. The fly in the ointment is that a large striped fish was cut into more than a dozen pieces, delicious is delicious, and the appearance is destroyed.
Now that I think about it, if I can have a special tool, slender, put the whole local fish in it, heat it below, and talk while eating, that feeling can reflect the integrity of the fish, but also see the intention of the hotel. Qingdao Evening News reporter Shan Yanchun

According to experts from Qingdao Ocean Development Bureau, the East China Sea, the Yellow Sea and the Bohai Sea are all white-banded fish, which are similar to the "local knife fish" commonly known by the public, and the taste is better, the meat is delicate, the taste is tender, and the fish bones are relatively soft. The South Sea strip fish has a relatively poor taste, and the bones are relatively hard, containing granular hard bones. African striped fish have a worse taste, the meat of the fish is coarse and fishy, and it has a "powder" feeling when it is delicious.
So, how do you distinguish between these striped fish? Zhao Yueyang introduced that it is possible to distinguish between East Sea belt fish and African belt fish from the following aspects.
Figure: The East Sea belt fish is small and narrow, with a body width of about 4-7 cm and a body length of about 40-60 cm. The African striped fish is relatively "large", with a body width of about 6-10 cm and a longest length of about 1 meter.
Tail: East Sea belt fish is more symmetrical, from the head to the tail is relatively slowly "thin" down, the tail is thin and long. The African striped fish is broad in head and back, and is significantly thinner at the end.
Fish scales: The scales of the East Sea strip fish are white with a slight black, the scales are easy to fall off, there is no convex bone on the dorsal ridge, and the fish bones and spines of the African striped fish are relatively hard.
Organs: East Sea fish have smaller eyes, smaller black eyes, and more whites. The African striped fish has larger eyes and yellowish whites. The jaws of the East Sea strip fish are shorter, while the jaws of the African striped fish are significantly larger. The distinction between Qingdao's local striped fish and East Sea striped fish resembles that of southern striped fish, but it does not have the granular hard bones of southern striped fish, and the taste is delicate and tender compared with southern striped fish and African striped fish.
