Whether yellow croaker can be artificially cultivated, whether small yellow croaker can be artificia

Yellow croaker can be farmed.

Yellow croaker used to be one of China's important economic fishes, a unique endemic species in China, widely distributed from the southern Yellow Sea in the north, through the East China Sea, the Taiwan Strait, and south to the east of the Leizhou Peninsula in the South China Sea. The cultivation of yellow croaker is mainly based on cage culture, and the cage culture of yellow croaker should follow the standard of "pollution-free food: technical specifications for large yellow croaker breeding".

The difference between farmed yellow croaker and wild yellow croaker: generally there are fewer wild yellow croaker during the fishing moratorium, and there is a big difference between artificial yellow croaker and wild yellow croaker in appearance and taste. From the appearance of the wild yellow croaker body color is more yellow, the fish mouth is more red and bright, the fish body is more slender and slender, the belly is small, because of the relationship of the living environment, the mouth and eye circles of the wild yellow croaker will appear larger, the scales are thick, the meat is relatively close, and the taste is "chewy", and the taste is delicious.

The artificially cultivated large yellow croaker is more leisurely in the cage, lacks exercise, the body is fatter, the fish belly is more bulging, the skin color is dark yellow or gray, and the color of the fish lips is light. In addition, the fins of wild large yellow croaker are generally clean and complete, and the fins are long, and when caught from the sea, the swim bladder bursts due to the low air pressure and kills, so there is not much painful struggle. The scales and fins on the body do not leave traces of congestion.

Those fins look a little red, a little broken, and the fins are shorter; If the fish has red spots and scars on its body, it is certain that it is farmed. Because artificially cultivated large yellow croaker is generally kept in cages, it is easy to be injured when swimming in a small space. At present, some deep-sea farmed large yellow croaker is somewhat similar to the wild large yellow croaker, but the meat is a little soft to eat, and the taste is not as pure as the wild one.

The large yellow croaker is a fish belonging to the large yellow croaker species of the perciformes totoaba family. They have a long, flat body with a blunt head, a large cracked mouth, teeth, and scales on the surface of their body. They are yellowish-brown in color, and their fins are mostly yellow.

They live in coastal waters and sometimes move into freshwater. They are widely distributed in the Pacific Ocean, and in addition to Japan, Vietnam, North Korea, and other countries. They are carnivorous fish, and animals such as daphnia and shrimp can be their food.

Large yellow croaker is one of the common fish in China. From the point of view of the category, they belong to the large yellow croaker species of the family Totoaba of the order Perciformes. The body shape of this fish is relatively long and flat.

The head is blunt, the mouth is large, and there are teeth, which can function when hunting. They have scales, and all parts of the body are covered with scales except for the head. Their body color is yellowish-brown, and the fins are mostly yellow.

The swim bladder of this fish is relatively large and more pronounced, with a round tip and a pointed end.

Large yellow croaker lives in coastal areas and belongs to the offshore sea. In addition, they sometimes move in freshwater, and not all life activities are carried out in seawater. From the specific distribution range, the large yellow croaker is widely distributed in the world, not only in China, but also in many countries in the western Pacific Ocean, such as Japan, Vietnam, South Korea and other countries.

From the perspective of eating habits, large yellow croaker is a carnivorous fish, and they can eat many foods, such as water fleas, cephalopods, crustaceans, shrimp, and so on. Large yellow croaker is also an edible fish, and the meat is relatively delicious.

As mentioned above, large yellow croaker lives in near-shore areas, but they sometimes move into freshwater and adapt well to both saltwater and freshwater. Therefore, the large yellow croaker can be artificially cultivated, and they can be bred in the breeding pond, and the number of large yellow croaker bred by the farmer is generally relatively large. There are still many problems that need to be paid attention to in breeding large yellow croaker, such as the water depth, which can be controlled at least one meter deep, and the amount of dissolved oxygen in the water and the water quality need to be guaranteed, and they must be provided with sufficient food every day.

Small yellow croaker can be artificially farmed. Small yellow croaker is a warm fish in the offshore waters, and its living environment is relatively special, so artificial breeding is more troublesome. They are more difficult to breed, so there are not many people who breed them.

However, the current breeding technology is relatively high, and the economic value of small yellow croaker is relatively high, so some people breed small yellow croaker. When they are cultivated, they should be provided with a seawater-like environment, and the water temperature should be adjusted between 22-26 degrees. So that they can grow well.

Small yellow croaker is a relatively common fish in China, and we can often see this fish in the market. From the perspective of living environment, small yellow croaker is a kind of fish that lives in the ocean, and belongs to the warm temperature fish in the coastal waters. Because their living environment is relatively special, artificial breeding is more troublesome, and the difficulty of breeding is relatively large, so the behavior of breeding them is not particularly common.

However, this is not to say that small yellow croaker cannot be farmed in captivity. Because the small yellow croaker is more popular, the economic value of breeding them is relatively high, so there will be farmers who choose to breed small yellow croaker, but there are many problems that need to be paid attention to when breeding.

1. Feeding: When breeding small yellow croaker, an important problem is to feed them. Give them plenty of food on a regular basis so that they will grow well.

In general, it is appropriate to feed once a day in the morning and once in the evening. The feeding of small yellow croaker is relatively slow, so you can pay attention to this characteristic when feeding.

2. Salinity: As mentioned above, small yellow croaker is an offshore fish, so you need to pay attention to the salinity of the water used when breeding them. In general, salinity is sufficient. The salinity should neither be too high nor too low.

3. Water temperature: Small yellow croaker is a warm fish, so they have requirements for the surrounding water temperature, and the water temperature cannot be too low when breeding. In general, the water temperature is between 22 and 26 degrees Celsius.

Too high or too low is not good for their growth and will affect their appetite.

4. Dissolved oxygen and PH value: In the process of breeding small yellow croaker, the amount of dissolved oxygen and PH value in the water need to be paid attention to. The amount of dissolved oxygen is best more than 5ml per liter, if the amount of dissolved oxygen is too small, you need to find a way to replenish it. A pH index of around 8 is better.

Small yellow croaker is a more precious one, which is generally not easy to be artificially cultivated, because its growth environment is relatively special. But now the breeding technology is also constantly improving, so, can small yellow croaker be farmed? Can small yellow croaker be farmed in captivity?

Can small yellow croaker be farmed.

The farmed small yellow croaker is as fat as the farmed crucian carp, but it is not delicious and fishy.

Yellow croaker is one of the deep-sea fish. The concept of deep-sea fish is that of fish that live in waters between 2,000 and 10,000 meters. In China, large and small yellow croaker and hairtail fish are the three major deep-sea fish products in China.

Yellow croaker lives in deep-sea areas roughly below 2,500 meters, while hairtail fish lives in deep-sea areas below 2,000 meters below sea level. In the world, the main species of deep-sea fish are tiger grouper, blue spot, pink grouper, afterburner, megacarp, bonus fish, grouper, sesame grouper, sea tiger grouper, oil spot, blue spot, east star grouper and other fish.

How to breed small yellow croaker.

During the grow-up period, bait is generally cast once a day in the morning and once in the evening. Compared with red sea bream and jealous fish, large yellow croaker has the characteristics of slow feeding and small amount. Therefore, the hall socks should be slow to cast bait.

Growth is fastest during high temperatures. To maintain the natural body color of the golden color of the commercial fish. In the later stage of breeding, it is necessary to cover the cage with shade to control the light.

Optimal water temperature for growing 22-26. Salinity, dissolved oxygen 5 ml or more,.

The growing environment of the small yellow croaker.

Small yellow croaker, also known as small yellow croaker. Small yellow croaker, the habit is to overwinter in the deep sea in winter, migrate to the coast in spring, spawn in March and June, disperse in the near good sea to feed on the sea, mainly feed on mysis shrimp, hairy shrimp and small fish, and return to the deep sea in late autumn. Generally, the spawning ground of small yellow croaker is 10 25 meters in the coastal sea area, and the wintering ground is generally 40 80 meters.

The small yellow croaker has a small body with large scales and a pointed mouth. It is mainly distributed in the Bohai Sea, the Yellow Sea and the East China Sea in China, and the main production areas are in the coastal areas of Jiangsu, Zhejiang, Fujian, Shandong and other provinces in China. Yellow croaker, divided into large and small yellow croaker, is known as China's three major seafood together with hairtail.

<> yellow croaker can be farmed in captivity. Artificially cultured yellow croaker should be baited once in the morning and evening, and the bait is generally based on frozen upper fish, supplemented by the best powdered bait. The optimal water temperature for the growth of yellow croaker is 22-26, which can be covered with shade on the cage to control the hunger light, and the yellow croaker has a slow feeding and a small amount of waiting for the point to disappear, and the bait does not need to be too much, and it needs to be done a small amount many times.

Yellow croaker can be artificially cultivated, belongs to China's unique economic fish, wild species are mainly distributed in the Yellow Sea, East China Sea and other river basins, in 1992 began large-scale farming, breeding yellow croaker to build a pond near the water source, and the water depth is controlled at about 2 meters, during the breeding period to feed every morning and evening, mainly upper fish, with powdered feed.

Yellow croaker can be artificially cultivated, it belongs to China's important economic fish, is China's unique local species, mainly distributed in the Yellow Sea, East China Sea, Taiwan Strait and other river basins, in 1990 began to breed seedlings in batches, artificial breeding, in 1992, the scale of breeding gradually expanded.

When artificially breeding yellow croaker, a pond should be built near the water source and an open site, and the pond should be disinfected with quicklime water to eliminate the bacteria in it, and then injected water after 7 days of exposure, and the water depth should be controlled at about 2 meters, and then the healthy yellow croaker fry should be put into the pond.

In the process of breeding yellow croaker, the water temperature should be kept in the range of 22 to 26 degrees, and the feed should be fed twice a day, respectively in the morning and evening, the feed is mainly frozen upper fish, and then with cooked egg yolk, rice bran and other powdered feed, pay attention to the slow feeding of yellow croaker, and the amount of feeding should not be too much each time.

1. Yellow croaker can be artificially cultivated, after years of research, yellow croaker began to raise seedlings in batches in 1990, commercial fish breeding began to expand the scale from 1992, the output increased year by year, and the breeding provinces began from Fujian, and radiated to Zhejiang, Guangdong, Hainan and other provinces.

2. Yellow croaker is more precious, so we must be very careful and careful when choosing fish species, so as to improve the survival rate of yellow croaker breeding and reduce the loss of thin one. We usually choose fish species that are more uniform in size, robust and lively, with relatively complete scales, and have no internal and external injuries and no diseases for stocking, so that the fish can be managed in a unified manner.

3. Feeding management mode: There is a correct management model, which brings more help. In the process of feeding yellow croaker, it is necessary to choose the right food, which is the essence of feeding.

Yellow croaker can eat anything, the choice of feed is also varied, when we choose feed, consider its normal body needs, and then choose a suitable feed. It will bring him better growth nutrition.

4. The daily management of yellow croaker has become the most difficult thing in the industry. It is necessary to know some normal management knowledge, especially for ponds, to observe three times a day. It is necessary to look at the normal growth status of yellow croaker every time, and if there is an environment for reverse growth, it is necessary to carry out timely remediation.

<> small yellow croaker can be artificially cultivated. The main production areas of small yellow croaker are Jiangsu, Zhejiang, Fujian, Shandong and other provinces and coastal areas in China. The living habit of small yellow croaker is to overwinter in the deep sea in winter, migrate to the coast in spring, wait for spawning between March and June, and then disperse to feed in the offshore sea, and generally feed once a day in the morning and evening during the feeding period.

Small yellow croaker has the characteristics of slow feeding and small amount, so the bait should be slower.

1. Can small yellow croaker be artificially cultivated

1. Small yellow croaker can be artificially cultivated. The body of the small yellow croaker is relatively small but the scales are large, mainly distributed in the Bohai Sea, the Yellow Sea and the East China Sea, and the main production areas are in the coastal areas of Jiangsu, Zhejiang, Fujian, Shandong and other provinces in China. Small yellow croaker, large yellow croaker and hairtail are known as the three major seafood products in China.

2. The living habit of small yellow croaker is to overwinter in the deep sea in winter, migrate to the coast in spring, and wait for spawning from March to June, and will forage in the offshore area. Its diet consists mainly of mysy shrimp, hairy shrimp and small fish, and the small yellow croaker returns to the deep sea in late autumn.

3. During the feeding period, you can bait once a day in the morning and evening, the feeding amount of small yellow croaker is relatively small and the feeding process is very slow, so the bait should be slower. In order to maintain the golden body color of the small yellow croaker, it is necessary to cover the cage with shade to control the light in the later stage of breeding.

Second, what is the prospect of small yellow croaker breeding

1. At present, the breeding prospect of small yellow croaker is relatively broad. Because the small yellow croaker will fluctuate up and down according to the origin, weight, quality, quantity, market, wild or artificial breeding and other factors, and the small yellow croaker itself is tender and nutritious, and has high medicinal value.

2. At present, due to long-term overfishing and poor environment, wild small yellow croaker has become very rare, and artificially cultivated small yellow croaker has not been cultivated on a large scale, so the resources of small yellow croaker are also very scarce.

3. When carrying out artificial breeding, it should be noted that small yellow croaker likes to live in clean water. However, after a certain period of time, the water quality will be polluted by the excrement of the fish and the food residues fed to the water, and the bacteria and parasites in the water will also multiply, so in order to ensure that the water quality is clean, the amount of feed should be appropriate, and the water should be changed frequently.
