As the most important economic fish in China's marine fish, many consumers and even some seafood business owners think that there is only one kind of belt fish in China's coastal waters. I myself am engaged in seafood e-commerce, but I also know very little about the fish, although I know that there are several different kinds of fish, but I only know their famous names, such as: the sea with fish, the golden belt fish, the black eye with fish, but do not know their real scientific names.
With the thirst for true knowledge and the responsible attitude towards consumers, I thought it was necessary for me to figure out these fish, search through various websites, consult various academic libraries and encyclopedias, and finally sorted out this popular science article.
< h1 class= "pgc-h-arrow-right" > the research process of the classification of striped fish</h1>
I will not dwell on the specific research analysis, I will roughly describe the research process and results to ensure the scientific and rigorous nature of the research. The researchers collected a total of 866 striped fish from 7 populations of 866 striped fish from Sanya in Hainan Province, the east side of Beibu Bay in Baimajing, Shanwei in Guangdong Province and Meilin in Fujian Province, and combined with morphological data for biochemical analysis. At the fishing site, samples are taken, and the muscles, liver and eyes of the fish are frozen within 1 day after the live fish or immediately after death, and immediately put liquid nitrogen for preservation. According to the electrophoretic settlement, the variation of allele frequency genes of 11 isoenzymes in 3 species of fish and the genetic differences between populations were calculated.
Genetic similarity between 7 populations in 3 species
Through the study of these samples, these species of striped fish named according to locality can be summarized into 3 species of striped fish, and the genetic distance of these striped fish is above 0.22 (the coefficient of species identification criteria), so it can be determined as 3 species of striped fish. Why do I have to go through this at length, because the classification of species is not simply based on the color and morphology of the species to determine whether it is a new species, because it may also vary in natural growth.
We eventually classified three species of striped fish into: trichiurus haumela (trichiurus lepturus), short-striped fish (Trichiurus brevis), and South Sea ribbon fish (Trichiurus nanhaiensis).

The difference between three kinds of striped fish
White-banded fish
White-banded fish, a species of fish in the genus Oleander in the family Oleanderidae. The English name (Largehead hairtail large head band fish), also called high-fin belt fish, tooth belt or knife fish, there are also called crony, fat belt, oil belt, Tianzhu belt fish, their size is relatively large, the tail is slender as a whip, the dorsal fin is gray-white, there is no ventral fin, there is no scale, but there is a clear lateral line, the body is silvery white, the dorsal fin and pectoral fin are pale white, and the body length can be 234 cm larger.
It is one of the most important economic food fish in our country, with a huge production and is an extremely important economic catch, with an annual production of more than 500,000 tons worldwide. The main fishing methods are bottom trawls, scarf nets and fixed nets. The fishing season is in the spring and summer, and it is also a seasonally important sea fishing species along the northern coast.
The warm and tropical seas of the world, including the sea around Taiwan, are produced everywhere except the western part of the taiwan region.
White-banded fish are mid-gently migratory fish in warm waters , generally inhabiting open oceanic waters , with water depths between 60 and 100 m , often swimming as far as 350 m , or even deeper , and migrating to shallow waters during spawning. It prefers weak light and has a habit of vertical distribution day and night, reaching the deep water layer during the day and swimming to the surface layer at dusk, night and early morning. It is gregarious and extremely gluttonous, feeding on small fish and crustaceans.
White-banded fish are also divided into black-eyed striped fish and yellow-eyed striped fish, and these two types of striped fish are also common to consumers, and there must be consumers who will say how to buy?
1. Black-eyed fish
Black-eyed striped fish is delicious, tender meat, fishy taste is relatively small, life is mainly used to do steaming to eat, people who like a light diet can choose black-eyed striped fish.
2. Yellow-eyed striped fish
Summary: The individual of yellow-eyed striped fish is relatively large, the meat will be rougher, there will be some fishy taste, generally more suitable for braised or fried food, people who like to eat spicy diet can choose yellow-eyed striped fish.
Their differences are mainly between the eyes and the individual: the eyes of the black-eyed fish are black, while the yellow-eyed fish's eyes are yellowish; the black-eyed fish-banded individuals are generally smaller, while the yellow-eyed fish-banded individuals are generally larger.
Short striped fish
It is also known as the Chinese short-tailed striped fish and the Qiongtail fish, the English name (Chinese short-tailed hairtail). The short-banded fish is a carnivorous fish, with a slender and flattened body, a white dorsal fin, and a body length of up to 54.5 cm, mainly distributed in the waters around Hainan Province in China. Short-banded fish mature early and have small individuals, and their largest individuals cannot reach the length at which the other two species of banded fish begin to mature sexually.
South Sea strip fish
South Sea strip fish is also known as yellowfin striped fish, and Dongshan Island fishermen call it golden striped fish. Compared with the white-banded fish, the head is much smaller, the tail is shorter than the white-banded fish, because the dorsal fin is yellow and also called "yellowfin banded fish" (as shown above), generally inhabit the coast, mainly distributed in the southern part of the East China Sea and the South China Sea. Deep-sea , sandy mud bottoms , estuaries , and warm waters along the coastal coasts , generally inhabit the coastal waters of near-sediment or slurred continental sheds , with a water depth of between 20 and 50 m , often swimming as far as 150 m , or even deeper , and swimming back to shallow waters when spawning. It prefers weak light and has a habit of vertical distribution day and night, reaching the deep water layer during the day and swimming to the surface layer at dusk, night and early morning. It is gregarious and extremely gluttonous, feeding on small fish and crustaceans.
The gold belt is full of armor stainless steel, and the beautiful reflection can be blinded, which is actually a stainless steel belt fish. Of the several striped fish I've ever eaten, I personally think this one is the most tender and has the sweetest taste.
I hope that through this article can let more people understand the fish, so that more high-quality seafood can be shared with you, if you still want to know more about the knowledge of seafood can pay attention to me, welcome to leave a message to communicate.
