What species of crucian carp is crucian carp, the difference between sesame crucian carp and earth c

However, the adult fish are mainly plant-based. Because plant-based feed is abundant in water bodies, there are many varieties and a wide range of food intake. Vascular aquatic weeds.

The stems, leaves, buds and fruits are the favorite food of crucian carp, and are higher aquatic plants with water chestnut and lotus root.

Crucian carp have the best access to a variety of rich nutrients. Diatoms and some algae.

It is also food for crucian carp, small shrimp, earthworms.

They also love to eat young snails and insects.

The feeding time of crucian carp varies depending on the season. Spring is the peak season for feeding, and feeding is continuous day and night; Summer feeding time is morning, evening and night; All-day feeding in autumn; In winter, it is fed around noon.

Crucian carp, which live in the flowing water of rivers, like to walk in clusters. Sometimes along the water, sometimes against the water, to the shallows, bays, ravines, and reeds with abundant aquatic plants.

foraging for food in the bushes, laying eggs; When they encounter a place where the water is slow or stationary, and there is abundant bait, they take a temporary rest.

Crucian carp, which live in lakes and large reservoirs, also choose to live as a food. Especially in the shallow aquatic plant clusters, they are concentrated, and even in winter, they are greedy for grass roots, and most of them do not swim to grassless deep water for the winter.

Crucian carp that live in small rivers and ponds live when they encounter a current, and they choose to live when they encounter a current. In winter, they mostly dive deep underwater to spend the winter. Introduction to carp knowledge: Carp is named because of the cross texture on its scales. The body is fat and the meat is delicate.

It is produced in fresh water all over our country.

Rivers, lakes, ponds. It is produced all year round, but the fattest is produced from February to March.

The carp is willow-shaped, with a slightly raised back, whiskers on the mouth, large and tight scales, complete and typical fins, and less spiny flesh. According to the different growing waters, carp can be divided into river carp, river carp, and pond carp. The body color of the river carp is golden, with metallic luster, the chest and tail fin are red, the meat is crisp and tender, the taste is delicious, and the quality is the best; The scales of the river carp are all white, the body is fat, the tail is bald, the flesh is hairy, and the meat is slightly sour; The pond carp is blue and black-scaled, with hard spines.

The earthy flavor is stronger, but the meat is more tender.

Why do people like crucian carp? Old anglers must know it, because there are very few that specialize in breeding crucian carp. The reason is very simple, the growth of the crucian carp is relatively slow, in the wild environment, the crucian carp can generally only grow to more than 1 tael a year, and the growth is even slower after half a catty.

The body of the crucian carp is slender, the size is small, the mouth is small, and it is mostly golden yellow (the water quality is different), and the lateral line of the fish body is only 28 lateral line points are very clear, and the number of fish scales from the lateral line is only 28, and the fish scales are small. The back of the crucian carp is blue-black or yellow, the belly is white, the tail fin is thin and lighter than the body color, and the flesh is pale red after cooking. Fish lips are very thin, with little or no flesh on the gill shells; The head is round and small, and the transition between the head and the body is very smooth, so there is no protrusion of the body.

However, even in the wild river, the number of pure soil crucian carp is actually not much. It is mainly the new hybridization caused by the farmed hybrid crucian carp and the released crucian carp, resulting in a smaller and smaller number of pure native crucian carp. In terms of weight, the crucian carp rarely exceeds one and a half catties, and it takes at least 8 to 10 years for the crucian carp to grow to 1 catty, and even if it grows to about two, it will take years.

Crucian carp. Nowadays, anglers come into contact with crucian carp, which is commonly known as crucian carp. This type of crucian carp looks more like a crucian carp and is also prone to golden yellow. When it looks like a carp from a distance, it is currently in Sichuan.

The reservoir is commonly cultivated for this type of crucian carp.

The growth rate and individual of the crucian carp are larger than that of the crucian carp, which can generally grow to about 3 taels a year, and only takes about 3 years to 1 catty, and the adult body is much larger than the crucian carp. The biggest difference with the crucian carp is that the lateral line points on the body are not clear 28, and the tail is often not clear enough, and the scales are obviously larger than the crucian carp, and the body size is not as slender as the crucian carp. The mouth should be larger than that of the crucian carp, and the lips should be thicker......

Engineering crucian carp. The most common crucian carp on the market is Xiangyun crucian carp (engineering crucian carp), which is the Chinese Academy of Engineering.

The technical collaboration group led by Academician Liu Yun used the bioengineering technology of combining cell engineering and sexual hybridization to breed triploids.

The new fish species is also the most common species of crucian carp that is currently farmed. The appearance of Xiangyun crucian carp is similar to that of ordinary crucian carp, with a blue-gray back, a white abdomen, large scales, and a pair of small whiskers. The lateral line scales are generally 30 32 pieces, gonadal sterility, few internal organs, the abdomen is smaller than that of other crucian carp, and the back muscles are significantly thicker than other crucian carp. The growth rate of Xiangyun crucian carp is fast, which is 3 5 times that of ordinary crucian carp, and the largest individual can reach kilograms.

Both are a type of crucian carp. The scales of sesame carp are hard but the flesh is tender and delicious, and it prefers to grow in places with good water quality.

The cause of sesame carp is that crucian carp absorbs nutrients in the water and grows black spots on its body, which is called "sesame carp". Crucian carp, also known as wild crucian carp, refers to crucian carp that is native to natural waters. Crucian carp is a natural water, that is, crucian carp that breeds naturally in reservoirs, ditches and weir ponds.

It takes about three years for crucian carp to grow from seedlings to 150 grams (3 taels). In different waters, most of them are blue-gray, and some are golden yellow, and their scales are smaller and longer than those of the improved species of crucian carp on the same basis. The vitality of the crucian carp is stronger, and the physical strength is better than that of the well-bred fish, and it will not die easily after leaving the water for a while and a half.

1. Crucian carp.

Crucian carp is relatively rare in the market, so its ** is more expensive, but the taste is absolutely better than other crucian carp. The color of the body of the crucian carp is blue-gray, and it is a naturally grown crucian carp, that is, they can reproduce naturally in reservoirs or ponds, which can be regarded as the most authentic wild crucian carp. The crucian carp is very wild, slightly thinner, and very distinctly spinning cone, and the intestines in its belly are thin and long.

The biggest characteristics of this crucian carp are that it grows fast, has a very strong ability to resist diseases, is pan-feeding, and is easy to catch. Its vitality is so strong that it will not die within an hour of being out of the water, unlike any other fish.

2. Engineering crucian carp.

The engineering crucian carp is also called Xiangyun crucian carp, its appearance is no different from ordinary crucian carp, the back is also blue-gray, but its size is relatively small, the internal organs are few, so its abdomen is also relatively smaller than other crucian carp. Originally, there was no engineering crucian carp in nature, but after a long period of artificial cultivation, a new type of species was born from the intersection of crucian carp and carp, so it is said that the engineering crucian carp itself has no reproductive ability. It is characterized by its fast growth, which can easily get too close, and the growth rate is also 3 times that of other crucian carp, but it is not so delicious to eat.

The engineering carp is very resistant to disease, and there have been no diseases or large deaths in ponds and ditches.

3. Tall crucian carp.

The tall crucian carp is named because of its relatively high back, and it is also the largest crucian carp in the crucian carp species, its back is silver-gray, and the back is black and the color becomes lighter the further down until the abdomen is white. It mainly eats aquatic plants, moss, humus, etc. in the water, which has a certain purifying effect on the human body. The tall crucian carp has the characteristics of fast growth, strong disease resistance and strong reproductive ability, and is relatively large, which is conducive to better breeding.

Summary. Hello dear, the crucian carp crucian carp and carp are hybridized varieties, the so-called horse crucian carp is the common name for farmed crucian carp. Different from wild crucian carp, the growth rate of crucian carp is faster, it can grow to 3 taels in a year, and it can grow to 1 catty in three years.

It is not as slender as the wild ones, but is wider and larger, and looks like a carp from a distance. Hope it helps you <>

4. Qihe double-backed crucian carp, the meat is tender and delicious, and it is not resistant to low temperature. 5. Heterogeneous silver carp, less disease, high survival rate.

1. High-backed crucian carp

The tall crucian carp originated in the mid-70s of the last century, with the characteristics of large individual, fast growth, strong fecundity, etc., named because of the towering back, the maximum individual is 3000 grams, strong hydrophilicity, and is not suitable for raising in the mainland.

2. Peng Ze crucian carp

Pengze crucian carp is an excellent crucian carp species, the meat is delicious, the meat content is high, the nutrition is rich, and its body is plump, easy to transport, easy to hook, is conducive to live fish on the market, and is also a kind of production and sport fishing and development of fish.

3. Founder silver carp

Qihe double-backed crucian carp is produced in Qihe, Qi County, Hebi City, Henan Province, likes to live in warm water temperature, does not tolerate low temperature frost damage, and Qihe double-backed crucian carp meat is tender and delicious, but the number of reproduction is small.

5. Heterogeneous silver carp

The heterogeneous silver carp is based on the founder silver carp as the female parent, with the Xingguo red carp as the paternal parent, and the offspring obtained by artificial mating, the heterogeneous silver carp grows 2-3 times faster than the ordinary crucian carp, has strong life adaptability, less diseases, and high survival rate.

The main species of crucian carp in China are: high-backed crucian carp, Fangzheng silver crucian carp, Pengze crucian carp and Qihe crucian carp.

1. Gao Shiji called the back carp. It is a dominant species developed in Dianchi Lake and its water system in Yunnan Province in the mid-70s of the last century, with the characteristics of large individuality, fast growth and strong fecundity. It gets its name because of the high back.

The maximum individual is 3000 grams, and it is highly hydrophilic, so it is not suitable for raising in the mainland.

2. Founder silver carp. Founder silver carp is native to Shuangfeng Reservoir in Fangzheng County, Heilongjiang Province, and is a good silver carp species. The back of the square silver carp is blackish-gray, and the sides and abdomen are dark silvery-white.

3. Peng Ze crucian carp. Pengze crucian carp is an excellent crucian carp species selected and bred by Jiangxi Provincial Aquatic Science and Technology Personnel, with delicious meat, high meat content and rich nutrition. The body is plump, easy to transport, easy to temporarily raise, easy to hook and search, which is conducive to the listing of live fish, and is also a kind of fish that can be developed in both production and sport fishing.

4. Qihe crucian carp. The Qi River crucian carp is named after the Qi River, a mountainous river that flows east-west in the northern part of Henan Province. The Qi River does not freeze all year round, and from January to February, the water temperature is still above 10, and the water and grass on both sides of the Qi River bed are overgrown.

The excellent ecological environment has created good conditions for the growth and reproduction of Qihe crucian carp. Qihe crucian carp meat is tender and delicious, according to ancient records, Qihe crucian carp and fragrant rice, silk eggs, together are the three famous local tributes.

There are more than a dozen varieties of crucian carp, and the more common ones are Pengze crucian carp, black crucian carp, heterogeneous silver crucian carp, red crucian carp, Xiangyun crucian carp, Pu'an crucian carp, Qihe crucian carp, silver crucian carp, shrinking bone crucian carp and so on.

Crucian carp is very adaptable and easy to raise, whether it is deep or shallow water, running water or still water, good water or sewage, high temperature water (above 32) or low temperature water (0). Even in highly alkaline waters with pH = 9 or higher, lakes with high salinity can still grow and reproduce. In addition to the only disadvantage of crucian carp with many intermuscular spines, crucian carp has delicate meat, delicious taste, and high nutritional value and medicinal value.

Crucian carp has always been thought to exist only in the diploid form (2n=100), and since the 80s of the 20th century, relevant research results have proved that triploid crucian carp (3n=150) and tetraploid crucian carp (4n=200) have been reported successively, therefore, crucian carp has been found to have the characteristics of diploid and polyploidy coexistence. However, the mode of reproduction is significantly different, the diploid crucian carp reproduces in both sexes, while the polyploid crucian carp exhibits a dual reproductive pattern with both parthenogenetic gynogenesis and sexual reproduction.

Advantages and disadvantages of crucian carp species.

As far as we ordinary people are concerned, according to the growth value orientation, it can be directly divided into three categories: soil crucian carp, improved crucian carp and carp. The carp does not want to grow, the improved crucian carp is now the mainstream species of aquaculture, it and the crucian carp are the crucian carp in the typical sense, the carp of the bioengineered crucian carp grows fast but sells poorly, of course, the carp also belongs to the high-quality crucian carp.

In addition, it can also be directly distinguished or classified according to the two categories of body types of high-back type and low-back type, and it is generally believed that the relative body height of more than 40% is high type, and less than 40% is low type. In practical production, the high-backed crucian carp is much longer than the low-backed crucian carp, and the low-backed crucian carp (that is, the so-called) is now on the market"Sliver crucian carp"The most popular, but the growth speed is limited, which is exactly what it is called"You can't have it both ways"。
