What are the types of hairtail? What are the habits of hairtails?

Types of hairtails: bony fishes of the perciformes family, also known as saury and tooth ribbon fish;

Hairtail fish habits: Hairtail fish have poor swimming ability, floating in the middle layer of seawater during the day and descending to the bottom of the sea at night. When stationary, the head is upward, the body is vertical, and only the dorsal and pectoral fins are waved.

There are two types of hairtail: forktail deep-sea hairtail, narrow-headed hairtail, and sand hairtail. The habit of the hairtail fish is that it is afraid of strong sunlight during the day, and has the habit of walking diurnal and nocturnal, and the swimming ability of the hairtail fish is poor, and it floats in the middle layer of the sea during the day and descends to the bottom of the sea at night.

First of all, the hairtail is a kind of deep-sea fish, living in the sea area of 30 meters to 200 meters underwater, its characteristics are high temperature resistance, once the hairtail fish is fished, due to the change in sea pressure, it will die due to the bursting of the swim bladder, which is why the hairtail fish you see are dead fish with broken stomachs. The sea depth of the fishermen's shallow sea area can not meet the negative pressure requirements for the survival of the hairtail, so the unmanned hairtail is a migratory fish, which will carry out reproductive migration and wintering migration in the offshore and open sea according to the water temperature and seasonal changes, and these characteristics of them cannot survive in small ponds or small sea areas, and artificial breeding cannot provide such a migratory environment at present.

Introduction: Hairtail fish is a marine creature, and it is also a relatively common fish, and the body size of the hairtail fish is very distinctive, so it is easy to remember, so which sea areas do hairtail fish generally live in?

In fact, it is a deep-sea fish, so it is generally found at a depth of 60 to 100 meters. Hairtail fish does not live in shallow seas, and because the hairtail fish has relatively high environmental requirements and a wide range of distribution, it will be seen in the Indian Ocean and the western Pacific Ocean. In the coastal cities of our country, it is also possible to catch hairtail.

If it is in winter, it will live at a deeper bottom, and if it is in summer, it will live on a shallow seabed. Because the water temperature is too low in winter, if you live in a deeper place, the temperature will be higher.

Because the body of the hairtail fish is relatively long, and the body is relatively flat, and the whole body of the hairtail fish is silver-gray. Therefore, if the hairtail fish swims in the sea, the speed is very fast. And the character is also more ferocious, hairtail is a carnivorous fish, it generally lives on hairy shrimp and squid on the bottom of the sea.

However, hairtail fish is more nutritious, and it has more meat and fewer spines, so it is also very popular. After fishing, the body of the hairtail fish will quickly flatten due to the change of water pressure, which is why the hairtail fish will die quickly as soon as it is caught, and the body size will also become very flat.

First of all, as a deep-sea fish, hairtail fish is rich in a lot of high-quality protein and unsaturated fatty acids. These are all able to supplement nutrition, and the treatment also contains a lot of mineral elements that the human body needs, so it is beneficial to eat more hairtail. In addition, the hairtail is very easy to store and can be stored in frozen conditions.

Therefore, even in inland areas, you can buy hairtail in the supermarket.

Hairtail fish live in the waters of the Pacific Ocean, the Red Sea, the Dead Sea, the Yellow River and Lake Superior, as well as smaller lakes.

Hairtail is one of the most common types of fish in the sea. Hairtail is a carnivorous fish that does not swim well and often floats in the middle layer of the sea during the day and descends to the bottom of the sea at night.

Hairtail fish usually come in groups, and in the spring, they swim together to the shore for reproductive migration, forming a spring flood, and in the autumn they return to form an autumn fish flood. Hairtail fish is widely distributed, mainly in the western Pacific Ocean and the Indian Ocean, and can be found in the coastal provinces of China.

Hairtail fish is one of the most common in the sea. Hairtail fish is a carnivorous fish with poor swimming ability, floating in the middle layer of the sea during the day and descending to the bottom of the sea at night. When the water temperature rises in spring, the hairtail fish swims to the shore in groups to carry out reproductive recirculation, forming a spring flood. In autumn, groups return to their wintering grounds to form autumn fish floods.

Living habits: Hairtail fish are afraid of strong sunlight during the day and have the habit of "walking day and night". Hairtail is a warm-water coastal migratory fish, the Indian Ocean, the Pacific coast, China's South China Sea, East China Sea, Yellow Sea, Bohai Sea, the east coast of Taiwan Island, there are two regular hairtail fish floods every year

May and July and early summer are the growth and feeding migration period for juvenile hairtail fish; October and December are not autumn, which is the breeding and migration period for adult hairtails. 4. Predation skills: Ribbon fish have poor swimming ability, floating in the middle layer of sea water during the day, and descending to the bottom of the sea at night.

When the head is up, the body is vertical, only the dorsal and pectoral fins are waved, the eyes are fixed on the movement of the head, and when the prey is spotted, the dorsal fin vibrates rapidly, and the body bends and pounces on the food.

The fishing white, fishing tape, towing white, towing and light white printed on the ribbon packaging box mean different methods of fishing.

1. Fishing white, fishing belt: the method of baiting and luring capture, the silver carp and hairtail fish caught are called "fishing white" and "fishing belt", the fish body grows, the surface color is as white as silver, shining, and the quality is better than that of the general silver carp and hairtail.

Seepage 2, towing white and towing sliding chains, is fishermen use nets to catch a large number of silver carp and hairtail, compared with the above 1, the size of the fish is different, not as large as the fishing white, fishing belt types.

3. Ribbon fish, belonging to the family of bony fishes of the order Perciformes in the subphylum of vertebrates under the phylum Chordates. It is also called saury, skirting, fat belt, oil belt, tooth ribbon fish, etc., and it is fierce. Qingdao and Rizhao Yellow Sea coastal cities are called squid.

The body shape of the hairtail fish is flattened like a belt, silvery-gray, the dorsal fin and pectoral fin are light gray, with very small spots, the tail is black, the head of the hairtail is large, and the tail gradually becomes taper, the height is twice the length of the head, and the total length is about 1 meter. It is ferocious and feeds mainly on hairy shrimp and squid. It is mainly distributed in the western Pacific Ocean and the Indian Ocean, and is distributed in the Yellow Sea, East China Sea, Bohai Sea and South China Sea.

Hairtail fish is a very well-known edible fish species that lives in China. Many hairtail fish can be seen in the market, and it is basically distributed in all provinces of China. It is a very common fish.

These hairtails that can be seen in the market are generally caught from the sea, and there is the best season for hairtail fishing every year, during which many hairtails swim to shallower coastal areas and are then caught by humans. As for the artificially farmed hairtail, it is relatively rare in the market and very rare.

<> there is also an important aspect is the depth of the water, the hairtail fish itself lives in the sea, and it is tens of meters deep, their survival needs water to provide a certain pressure, if they leave the water will soon die, breeding them, you also need to master the depth of the water similar to their depth in the sea, that is, tens of meters deep. In addition, they have to be provided with food, including small fish and shrimp, and in large quantities. Hairtail fish is a common fish, and most of the fish that can be seen in daily life are wild, and there are few artificial breeds.

Although there are successful examples of artificial breeding of hairtail fish, there are few due to the high cost. The most important thing to cultivate hairtail fish is the water depth and feeding. Because the hairtail itself lives dozens of meters below the seawater, the environment here is relatively special, especially the water pressure will be in a specific range, and the hairtail fish cannot escape in such an environment, so it is best to create such a deep-water environment for them when breeding, and the cost is very high.

Of course, hairtail fish can only live in seawater, so the salinity should also be paid attention to, and it cannot be raised directly in fresh water. The second important aspect is feeding. Captails like to eat meat, and wild hairtails are meat-based.

When raising hairtail fish, they are provided with food every day, feeding on small fish and shrimp. They cannot be left without food for a long time. They are very aggressive and will eat their own kind if they go without food for a long time.

Do a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

Hairtail fish should choose to be farmed in the deep sea, because hairtail fish is a deep-sea fish, and when breeding, it is necessary to do a good job in the deep-sea area, to do a good job of escape prevention measures, to do a good job of shading measures, regular spraying of vaccines, regular spraying of feed.

Artificial breeding can be carried out, pay attention to the selection of the surrounding environment, but also pay attention to the selection of breeding skills, understand the specific breeding methods, and choose a suitable environment for breeding.

The pond must be large, the water source must be wide, the temperature must be appropriate, and the virus must be disinfected and disinfected in time to avoid the case fatality rate, and the oxygen supply must be provided in time.

Hairtail fish live in deep water and cannot be artificially cultivated, and the hairtail fish we usually eat are fishermen who go out to sea to catch them.
