Hairtail, small yellow croaker, large yellow croaker, and cuttlefish were known as the four major fisheries in China. They were once very popular. Later, as people overfished and the resources of large yellow croaker depleted, small yellow croaker and cuttlefish were facing the same dilemma. only the hairtail was growing vigorously, and it is still growing today. The output is very high, and it is deeply loved by people.
If you want to know whether hairtail can be farmed by yourself, you must first understand the species of hairtail. Many people think that it is often eaten like hairtail, and everyone knows what it looks like. However, what we don't know is that there are several types of hairtail.
There is a kind of king hairtail that has been more popular in recent years. This fish is similar to the fish we usually eat, but it is much longer than ordinary hairtail. Although it is similar in appearance, it is still different from real hairtail.
According to seafood research and development manufacturers, the hairtail we often eat is Perciforme Hairtail. There are many species of this fish in the eastern coastal areas of my country: Isofin catfish, Narrowhead hairtail, Small hairtail, Sandtail, Hairtail, Razortail, Deep-sea Hairtail, Cattail fish, and Anchovy. But what we often eat is hairtail of the genus Hairtail.
Hairtail is divided into South China Sea hairtail and East China Sea hairtail. The East China Sea hairtail is small and narrow, while the South China Sea hairtail is a bit larger. The East China Sea hairtail has closed eyes. The South China Sea hairtail is small, with small black eyes and more white eyes. If the white hair of the East China Sea hairtail is yellow, it is from the Middle East or Africa. The East China Sea octopus is more delicious than the South China Sea octopus, and the meat is tender.
Hairtail is rich in fat, protein, phosphorus, iodine and other nutrients needed by the human body, and has the effects of strengthening the heart and kidney, reducing inflammation and phlegm, eliminating fatigue, improving memory, and preventing high blood pressure.
Hairtail is a treasure all over its body. Its silver scales are not scales, but a layer of epidermis formed by special fats, called'silver fats', which are high-quality fats with high nutritional value, no smell and taste, and contain unsaturated fatty acids. And other substances that are extremely beneficial to the human body.
Since hairtail has high nutritional value, why is it not cultivated artificially?
The answer is: no need
1. Hairtail is a deep-water fish. The characteristic of deep-water fish is that it is resistant to high pressure. Although we often taste hairtail, we can't see live hairtail fish. The reason is that hairtail cannot survive without high pressure.
2. Hairtail is a migratory organism and is not suitable for artificial breeding
3. Hairtail has been caught for a long time, and the output is still so high, people don’t need to spend time and energy to study hairtail breeding
4. Hairtail has fierce habits and inhabits deep waters. Research on it still needs to be in-depth.
Seafood R&D manufacturers say that if they have to artificially breed hairtail, the cost of breeding is too high, because it needs to be cultured in the deep sea. Of course, you can say that we can make a large net and put the hairtail on the seabed to raise it, but Have you considered the size of the net? How to manage it? If you don’t manage it and let it grow naturally, then why use a net to live?
