CATDOLL : CATDOLL: Can hairtail fish be raised artificially?

Can hairtail fish be raised artificially?

Hairtail fish is resistant to high pressure. We often taste hairtail fish, but we cannot see living hairtail fish. So can hairtail fish be artificially bred? Below are the reasons why hairtail fish cannot be artificially bred, which I have carefully sorted out for you. Let’s take a look.

The reason why hairtail cannot be artificially bred is that it cannot survive without high pressure. Furthermore, hairtail is a migratory creature and cannot be artificially bred.

If it is possible to farm it, the cost is too high. Hairtail is a deep-sea fish. If it is not farmed in the deep sea, it will not be able to meet the "negative pressure" environment it lives in, and it will die because it cannot adapt to the environment. Humans can make a very large net and put it on the seabed to farm, but how big a net is needed? There are too many unexpected things, and the input is not equal to the output.

The economic value of hairtail

Hairtail is the most productive economic fish in my country's coastal areas. In the 1970s, the annual output was generally around 500,000 tons. In the 1990s, it rose to more than 1.1 million tons. Later, the output continued to decline, but it was better than that of large and small yellow croakers, and fish seasons could still be formed. In recent years, through fishing bans and publicity and education on protecting fishery resources, overfishing has been better controlled, keeping the production of hairtail at a relatively stable level.

Medical value

Hairtail has certain medicinal value. According to ancient and modern Chinese medical and aquatic medicine books, hairtail has the functions of nourishing the liver, dispelling wind, and stopping bleeding, and is effective in treating bleeding, sores, carbuncles and other diseases. Hairtail scales are the raw materials for making antipyretic and analgesic tablets and anti-tumor drugs. The scales contain a variety of unsaturated fatty acids, which have a significant effect on lowering cholesterol. It is suitable for people with long-term illness, dizziness due to blood deficiency, shortness of breath and fatigue, thinness due to lack of food, and malnutrition. Traditional Chinese medicine believes that it can warm the stomach and replenish the deficiency, and it also has the effects of moisturizing the skin and beautifying. However, people with sores and scabies should eat less.

Active ingredients: Every 100 grams of hairtail meat contains 19 grams of protein and 7.4 grams of fat, and no other nutrients are found. Hairtail scales also contain a variety of unsaturated fatty acids, fibrous substances (in hard protein), 6-thioguanine and other active ingredients.

Health function: Hairtail meat contains a variety of nutrients, and hairtail scales can lower cholesterol, prevent arteriosclerosis, prevent coronary heart disease, fight cancer, etc.

Development status and prospects: Scientists have found that rats fed with hairtail scale oil can reduce blood cholesterol and have good hair growth. In 1986, Japanese professor Tadaki Kishida pointed out that the fibrous substances contained in the hard protein of hairtail scales can inhibit cholesterol and also fight cancer.

Dietary value

The meat of hairtail, small hairtail and sand hairtail. Hairtail is also called whipfish, frigate fish, sea knife fish and scale knife fish. It is distributed in the Yellow Sea, Bohai Sea, South China Sea and East China Sea in my country. After obtaining, remove the head, fins and internal organs, wash and use fresh.

There are more and more hairtail farmers. What conditions are needed to raise hairtail?

The tastier something is, the harder it is to raise it. Yellow croaker can be raised, but is it still yellow croaker? It tastes terrible! It is said that imitation of wild yellow croaker has been successful, but the breeding cost is high, and it is still a high-end product, with a price of over a thousand yuan per catty, but it is still hard to find one. The yellow croaker at the New Year's Eve dinner is really raised in the aquarium, and the posture of the hairtail in the water is very interesting, floating vertically in the water. They can live well in an aquarium. They do not need an extreme deep sea environment.

There are studies on hairtail now, and artificial breeding by Zhejiang Zhoushan Fisheries Research Institute has achieved initial success, but there is still a long way to go before large-scale popular breeding. At present, the market mainly has wild East China Sea hairtail and offshore hairtail. East China Sea hairtail tastes better, while offshore hairtail has a fishy smell and rougher meat. Hairtail is farmed, and the earliest one was Ningbo University. However, it is not raised until it is supplied to the market. Hairtail is a long-distance migratory fish, and it is not tasty if it is artificially cultivated. In the past, farmed large yellow croaker was full of fat, and the taste was completely different from wild ones. Ningbo University raises it a little bigger and then releases it into the sea.

Hairtail is a deep-water fish. It will die quickly due to loss of pressure when it comes out of the water, so it is difficult to breed it. The problem with hairtail is not breeding, but what kind of medicine you spray to keep it fresh. I have never seen live hairtail in the market since I was a child. I have only seen it once on a boat, and it died soon after it came out of the water. Hairtail is a deep-sea fish. The high-pressure living environment is difficult to simulate. At present, research on it needs to be in-depth. In addition, hairtail is a migratory fish. The living habits are not suitable for breeding. In addition, hairtail itself has no scales and is ferocious by nature. It often kills its own kind. In summary, hairtail is difficult to breed.

Theoretically, it is still possible to farm them with the current technology! But it is not necessary and it is not cost-effective. Although the fishing resources have declined, the output is still enough for people to consume. Moreover, hairtail is a deep-sea fish. When swimming, the body of hairtail leans forward slightly and generates power by flapping its dorsal fin. Hairtail is a ferocious carnivorous fish and will even kill each other. They often lurk in deep waters during the day and float to the surface of the sea to feed at night and on rainy days.

To raise hairtail, you need a large warm pond, an oxygen generator, and add fish feed every day, so that the hairtail can grow better and better.

The air should be fresh, and the water should be changed frequently. The water resources must be sufficient and the temperature must be above 20 degrees. There must be fresh food every day, etc. These are the conditions required for breeding hairtail.

First of all, you have to attend training on the breeding technology of hairtail, and then you will have your own place.

It is very difficult to farm hairtail because they are deep-sea fish. There must be deep enough water and huge pressure for them to survive. Otherwise, they will easily die.
