The benefits and disadvantages of eating Qianyu, what kind of fish is Qianyu

The benefits and disadvantages of eating Qianyu are as follows:

Benefits:1Supplemental nutrition: Qianyu is rich in protein, fat, vitamins, minerals and other nutrients, and moderate consumption can help replenish the nutrients needed by the body.

2.Maintain metabolism: The unsaturated fatty acids and proteins in the fish help to maintain the body's normal metabolism.

3.Promote tissue protein renewal: The protein components in the fish can promote various metabolisms of the body and help tissue protein renewal.

4.Maintain the structure of bone cells: Qianyu is rich in calcium, and eating some in moderation can supplement the calcium needed by the body and maintain the structure of bone cells.

Disadvantage: 1Indigestion: If you eat too much fish for a long time, it may lead to a lack of nutrition, which is not good for your health, and may cause indigestion and other diseases.

In conclusion, Qianyu is a nutritious aquatic product, and eating it in moderation is beneficial to the body, but care should be taken to avoid overeating.

It's a catfish, right? A friend of mine deals in catfish.

He is a graduate of Southwest Agricultural University, and I consulted him specifically for you. So my answer is absolutely original and authoritative, and all copying is not allowed.

First of all, the first approachability of catfish is because the growth ability of catfish is stronger than that of other fish species, so the corresponding feeding conditions will not be as harsh as other fish species. In this way, the cost of catfish farming is correspondingly low. In addition, catfish is a fatty and easy-to-cook meat fish, so there are many ways to cook it, and there are many ways to cook it that are both simple and delicious.

Therefore, in this respect, the cooked food cost of catfish is more advantageous than that of other meats.

So the ** of the catfish is cheaper.

But the low price of the catfish definitely does not mean that its meat quality is low. On the contrary, catfish is very nutritious. Some people say that catfish grew up eating meat and are dirty, which is the idea of many people who do not have professional knowledge.

In general, the food eaten by the catfish is completely transformed into its own meat nutrition, so the quality of the catfish food has nothing to do with its feed**.

The reason why catfish is like pork fat adapts is that it has a high fat content of fish. But eating catfish often does not mean that you will gain weight. Because the fish fat of catfish is unsaturated fatty acids.

It is not the same as the fat of pork. The fat of pork is saturated fatty acids, and eating it will make you fat. The unsaturated fat of catfish contains many essential nutrients that are difficult to find in other foods, such as OEGA-3, which is beneficial to the cardiovascular system.

of chemical nutrients. There is also DHA, which is conducive to brain development and memory cranial nerves.

of growth. In addition, catfish is also rich in protein and other trace elements.

So eating more catfish not only does not hurt, but also has many benefits.

However, because of the fatness of catfish meat, it is not necessarily very scientific to eat it often, after all, eating a single meat for a long time is not enough to balance nutrition, it is recommended that you eat it with other ** dishes are more scientific. For example, with vegetables, eggs.

Finally, I wish you a good appetite every day.

It is also called "pincer fish" and is a type of catfish。The body shape of the fish is relatively long, the front part is wide, the back part is narrow, the head is relatively small, there are 4 pairs of whiskers on the side of the mouth, and there are no scales on the surface of the body, so it belongs to the scaleless fish.

They have a pale gray back and a white belly. It lives in the freshwater of North America and is widely distributed in Canada, the United States, and Mexico. The fish can be cultivated artificially and in the form of freshwater farming. The fish is edible, and the meat quality is relatively good.

The reproductive habits of the fish

They spawn in rivers, lakes, reservoirs and ponds under rocky protrusions, or in submerged trees, stumps, roots or burrows in river channels. The males of the pincer fish are typical nesting fish, driving away the females after mating with the females and guarding the development of fertilized eggs until hatching.

Generally, the spawning temperature range of catfish is 21 29, the optimal temperature is 26, and the water temperature is more than 30, which is not conducive to the embryonic development of fertilized eggs and the survival of fry. The breeding season of catfish in the Changfunai and river basins is June to July.

The back is light gray on both sides of the body, the abdomen is milky white, and there are obvious and irregular spots on both sides of the juvenile body, and the spots on the adult fish are gradually inconspicuous or disappear.

1. Qianyu, also known as pincer fish (qiányú), is the main catfish species in North America. Its official origins are Missouri, Iowa, Nebraska, Kansas, and Tennessee in the United States, and its colloquial name is"Channel cat"。

2. Qianyu is one of the most popular objects in the United States, and it is the most famous in the aquaculture industry. It is also called spotted catfish, which has the characteristics of thick meat without thorns, smooth skin and tender meat, fat and delicious.

3. Qianyu is now one of the main freshwater aquaculture species in the United States. Spotted catfish is a kind of catfish introduced by Hubei Provincial Institute of Fishery Sciences in 1984 at the same time as the clouded catfish, after several years of research and promotion of culture, it has been confirmed that this species of fish is suitable for breeding in most areas of China. It mostly grows in sandy or gravel bottoms with unpolluted water quality or large and medium-sized rivers with fast flow speed; It can also live in brackish and freshwater waters.

4. The pincer fish originates from the New Northern Boundary and is distributed in the eastern and northern parts of Quebec and the United States, and also in northern Mexico. Later this species was introduced to inland lakes in Europe and some places in Malaysia. Canada's pincer fish are abundant and are found not only in the Great Lakes, but also in the area around Lake Nipigon.

5. In addition to tonifying the spleen and water, it can also ventilate and reduce flatulence, tongfish, yin and yang, blood and deficiency, heart and kidney, swelling and other effects, and has a certain therapeutic effect on edema, beriberi, backache and leg weakness, hemorrhoids, ringworm scabies, earache, trachoma, and is also beneficial to lactation and blood supplementation, prevention of measles, chronic nephritis, prevention and treatment of tuberculosis, and is suitable for almost all ages.

黔鱼 (qián yú) is the main species of catfish in North America. It is also called spotted catfish, and it has the characteristics of thick meat without thorns, smooth skin and tender meat, fat and delicious.

Its official origins are Missouri, Iowa, Nebraska, Kansas and Tennessee in the United States, and it is commonly known as the "channelcat".

Both the catfish and the catfish are freshwater fish in China, and their main differences are as follows:

The scientific name of the catfish is different: the scientific name of the catfish is Glyptosternon maculatum, while the scientific name of the catfish is Megalobrama amblycephala.

The morphological characteristics are different: the body shape is relatively flat, the head is wide and developed, and it is a benthic fish; The catfish is a chubby fish with a slightly smaller head, making it a swimming fish. In addition, there are differences in the colors of the two:

The body of the fish is black-brown or grayish-brown with irregular dark spots; Whereas, catfish usually have a silvery-white body with some fine black spots covering the scales.

Different growing environments: The two species of fish grow in different environments. It is mainly distributed in Guizhou Province, which is led by Zen in China, and inhabits the middle and lower reaches of the Pearl River Basin and major rivers in Guizhou. Catfish is mainly distributed in Southeast Asia, the middle and lower reaches of the Yangtze River and the Pearl River Basin.

Although they differ in morphology, habits, and habitats, they are both beloved and delicious fish that are often used in a variety of fish dishes.

Qianyu and. Qianyu is also known as bearded catfish, fatty fish, catfish, bearded silver carp, sticky fish, raw larvae, and ray. Catfish are found almost all over the world, and most of them live in fresh water such as ponds and rivers, but some species live in the ocean.

The distinctive features are the scaleless body, the surface of the body is mucus, the head is flat, the mouth is broad, and the upper and lower jaws have four whiskers.

Ayu is not only rich in nutrients like other fish, but also has delicate meat, rich flavor, few spines, appetizing, and easy to digest, especially suitable for the elderly and children. It is rich in nutrients such as protein and minerals, and is especially suitable for people who are frail and malnourished.

Catfish are long-snouted bass. The long-snouted bass is a demersal fish. They often live in the waters of rivers and bays with slower currents, deep water and many stones.

It feeds mainly on aquatic insects and their trapped or larvae, crustaceans, small molluscs and small fish. It is distributed in the Liao River, Huai River, Yangtze River, Min River to Pearl River and other river systems in eastern China and western North Korea, with the Yangtze River water system as the main system.

In summary, the fish is an alien species, mainly growing in ponds and rivers and lakes, and its meat is delicate, suitable for the elderly and children. Catfish mainly survive in rivers and rivers, and belong to the bottom fish, with delicate and tender meat, delicious and delicious, suitable for high-end consumption.

1. Eat fish to fight depression.

There is a special fatty acid in the body of fish, which is related to the "heart hormone" in the human brain. It has the effect of relieving mental tension and balancing emotions. People who don't eat fish or eat less fish tend to have lower levels of "happy hormone", and Americans don't eat fish often, so more people suffer from depression.

2. Eat fish to prevent asthma.

Because the unsaturated fatty acids contained in fresh fish can prevent or reduce the production of inflammatory mediators in the body, and the attack of asthma is closely related to the release of inflammatory mediators. In addition, unsaturated fatty acids also have a certain effect on reducing tracheal inflammation, thereby helping to prevent the occurrence of asthma,** or reduce the degree of asthma symptoms.

3. Eat less fish and dementia.

Scientists believe that DHA is an essential nutrient for the activity and vitality of brain cells, which helps to improve the transmission of nerve information and enhance thinking and memory. Therefore, eating more fish in older people can reduce the occurrence of dementia.

4. Eat fish to prevent stroke.

Studies have shown that the higher the content of protein and sulfur-containing amino acids in the diet, the lower the incidence of hypertension. Fish protein is rich in egg amino acids and taurine, both of which are sulfur-containing amino acids, which can affect the regulatory mechanism of blood pressure, increase urinary sodium excretion, thereby inhibiting the effect of sodium salt on blood pressure and reducing the incidence of hypertension.

5. Eat fish to prevent aging.

There is a very famous prime minister in German history named Bismarck, who has been overeating and oversmoking for many years, and at the age of 68, his body is weakened, his face is full of wrinkles, and his eyes are cloudy, as if death is beckoning to him.
