Yes! Hairtail is a marine fish that produces eggs that hatch before reproducing. It is a fish, unlike some fish that are called fish (such as whales, which are viviparous and reproduce, so they are actually animals, not fish).

What I'm asking is, is it fish...

2. Is hairtail a deep-sea fish? How deep does it live?

Hairtail is not a deep-sea fish. Deep-sea fish is a type of marine fish, which is divided according to the depth of distribution of marine fish. Specifically, deep-sea fish need to live at least hundreds of meters deep, and some even live in the sea thousands of meters deep. Hairtail only lives in the sea at a depth of 60 to 100 meters, and cannot be considered a deep-sea fish. Although hairtail is not a deep-sea fish, they are a very typical marine fish, widely distributed, and can be found in basically all seas.

1. Is hairtail a deep-sea fish? Deep-sea fish refers to a type of marine fish, which is divided according to the depth of their life. Since they can generally adapt to environments with depths of hundreds or even thousands of meters, they are truly deep-sea fish, and their bodies can also adapt to the very high-pressure living environment in the deep sea. Hairtails are not in the category of deep-sea fish, which can be seen from the depth range of their main lives. Generally speaking, they only live at a depth of 60 to 100 meters. Although the depth of distribution is relatively deep compared to freshwater fish, it is still considered to live in a shallower place compared to deep-sea fish.

Although hairtails are not deep-sea fish, they are a typical marine fish that live in the ocean and have always lived there, and can only adapt to similar environments. Hairtails are also a very popular marine fish that can be used as food. They are distributed in many sea areas in my country, so they are basically a common fish species in the country, and you can often see this fish for sale in the market.

2. How deep does the hairtail live? As mentioned above, hairtail is not a deep-sea fish, because its distribution depth range is only 60-100 meters, and it is rare to find fish deeper than 100 meters. Deep-sea fish are at least distributed in places with a depth of hundreds or thousands of meters, and live in deeper places than hairtail. The deeper you go into the seabed, the greater the surrounding water pressure will be. The pressure that deep-sea fish can withstand is very large. Although hairtail can also withstand a certain amount of water pressure, it is obviously not as strong as deep-sea fish. Of course, although hairtail is not a deep-sea fish, it is also difficult and costly to breed it artificially.

3. What is the nutritional value of hairtail? Why do we rarely see live hairtail?

Hairtail fish is delicious, with less bones and more meat, and is very popular. Hairtail fish is a saltwater fish, and even with simple cooking methods, it can have a different and delicious taste. Today we will give you a detailed introduction to the nutritional value of hairtail fish, why we rarely see live hairtail fish, and how to choose qualified hairtail fish.

Nutritional value of hairtail

1. Rich in unsaturated fatty acids. Hairtail is a kind of marine fish, rich in unsaturated fatty acids, which can lower cholesterol.

2. Rich in minerals, such as magnesium, copper, phosphorus, iron, calcium, iodine, etc., which can strengthen bones and prevent thyroid diseases.

3. 6D-thioguanine. According to data, this substance is a natural anti-cancer agent, but its content in food is low.

4. Rich in protein. Fish protein is delicate and easy to absorb. It can supplement the human body's amino acids, improve immunity, and promote growth and development.

5. Lecithin. It has the effect of delaying brain aging. In particular, the DHA content in hairtail is higher than that in freshwater fish. It is a nutrient required for brain development and can improve memory and thinking ability.

The medicinal value of hairtail

In traditional Chinese medicine, hairtail has the functions of nourishing the body, detoxifying, stopping bleeding, and nourishing the liver. It is suitable for people with long-term illness, postpartum lactation, and traumatic bleeding. In the "Sui Xi Ju Diet", it is recorded that "hairtail warms the stomach, nourishes the body, and moisturizes the skin."

However, "Yao Xing Kao" also records the taboos on eating hairtail: "Eating too much hairtail will cause scabies." People with skin diseases, ringworm or allergies should be careful to avoid eating too much.

But why do we rarely see live hairtail?

We have seen a lot of live seafood, but live hairtail fish are rare. This is mainly because hairtail fish are generally deep-sea fish. After being taken out of the water, due to the reduction of external pressure and excessive abdominal pressure, they will explode, that is, their internal organs will rupture and die.

Even if aquaculture technology is now used or some non-deep-water hairtail fish no longer die immediately after being taken out of water, it is still not easy for them to survive for a long time, and freezing is still the most commonly used preservation technology.

About the selection of hairtail

1. Choose a seafood market with high liquidity. Because of the high liquidity, the goods are generally fresher and a box of hairtail will not be sold for several months.

2. Avoid choosing processed semi-finished products. It is best to choose hairtail with a head and tail that looks good, and let the merchant process it after purchase.

3. Choose neat hairtail with head and tail. If the head, abdomen or tail is severely damaged, it may have been thawed repeatedly.

4. Avoid hairtail that has turned yellow on the outside. The yellowing on the outside means that it has a longer shelf life.

5. Avoid choosing hairtail with a fishy smell. It is normal for hairtail to have a fishy smell, but a foul smell indicates that the hairtail has been thawed repeatedly or has gone bad.
