There are several varieties of crucian carp and what is the best species of crucian carp

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.

1. High-backed crucian carp.

The high-backed crucian carp was in the mid-seventies of the last century in Dianchi Lake, Yunnan.

A population developed in the area, named because of the high back, has the characteristics of large individuals, fast growth, rapid reproduction, etc., a single individual can grow up to 3000 grams, not suitable for breeding in the mainland.

2. Founder silver carp.

Founder silver carp is native to Fangzheng County, Heilongjiang Province.

Shuangfeng Reservoir is a good species of silver carp, the back of the square silver carp is black gray, the side of the fish body and abdomen are white, and the maximum length of a single individual is to kilograms, generally about 1 kilogram.

3. Peng Ze crucian carp.

Peng Ze crucian carp is an excellent crucian carp species cultivated by Jiangxi Provincial Aquatic Science and Technology Personnel, the meat quality is delicious, the meat yield is high, the nutrition is rich, the body is plump, easy to transport, it is a kind of fish species that develops together with aquaculture and sport fishing.

4. Qihe double-backed crucian carp.

Qihe double-backed crucian carp is native to Qi County, Hebi City, Henan Province.

It is named after the Qi River, a mountainous river that flows from east to west. Qi River perennial flow is not ice, Qi River riverbed on both sides of the water and grass are thick, good ecological environment for Qi River double-backed crucian carp provides a good breeding habitat conditions, Qi River double-backed crucian carp is delicious, Qi River crucian carp and seedless dates, silk wrapped duck eggs together, is the local three major tributes.

5. Heterogeneous silver carp.

The heterogeneous silver carp is artificially inseminated with the founder silver carp as the female parent and the Xingguo red carp as the paternal parent.

The offspring obtained from mating are 2-3 times faster than the growth rate of ordinary crucian carp, and its adaptability is strong, the survival rate is high, and there are few diseases, so it is a good artificially bred species.

There are more than a dozen varieties of crucian carp, the more common ones are Pengze crucian carp, black carp, heterogeneous silver carp, red carp, Xiangyun crucian carp, Pu'an crucian carp, Qihe crucian carp, silver crucian carp, shrinking bone crucian carp, etc., among which Peng Ze crucian carp is native to Pengze County, with the characteristics of disease resistance and adaptability, and the black crucian carp mostly lives in the water bath with aquatic plants, and its body is black-brown.

1. Peng Ze crucian carp

There are more than a dozen species of crucian carp, the more common crucian carp species are Peng Ze crucian carp, Peng Ze crucian carp is a special product of Peng Ze County, Jiujiang City, Jiangxi Province, it has the advantages of large size, fast growth rate, disease resistance and strong adaptability, and the back of Peng Ze crucian carp is dark gray-black, and the abdomen is gray-white.

2. Black crucian carp

The black carp is a fish of the genus Crucian carp of the family Cyprinidae, its body length is centimeters, the head is relatively short, the eyes are located above the central axis on the side of the head, and the body of the black carp is black-brown, the abdomen is silver-gray or black-gray, and the black carp is an omnivorous fish, mainly feeding on plants, plankton and animal carcasses.

3. Heterogeneous silver carp

Heterogeneous silver carp is a new variety obtained by artificial breeding of the Chinese Academy of Sciences, it is based on the natural square silver carp as the female parent, Xingguo red carp as the paternal parent, after artificial insemination to obtain the offspring, and the heterogeneous silver carp has strong stress resistance, easy to breed, like to eat rotifers, aquatic insects, diatoms, cladopods and other foods.

4. Red crucian carp

When raising red carp, it is necessary to build a pond with an area of 1-5 acres, and then dig out the excessive silt at the bottom of the pond, and then sprinkle quicklime on it for disinfection, and finally put the red carp fry into the pond.

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"。

1. Founder silver carp

Founder silver carp, a specialty of Fangzheng County, Heilongjiang Province, has the characteristics of small head, thick back, high meat yield, cold resistance, strong disease resistance, fast growth and large individuality. In 2010, it was registered as a geographical indication of agricultural products by the People's Republic of China, and the scope of protection includes the original seed farm of Founder silver carp, Shuangfeng Reservoir and Shuanglong Reservoir in Fangzheng County.

2. **Crucian carp

**Crucian carp is a new aquatic seed farm in Tianjin City, with the sluggard carp as the female parent and the red carp as the paternal parent, and the carp carp hybrid obtained through distant hybridization, which is a new freshwater fish species approved by the National Aquatic Species Examination and Approval Committee and approved by the Ministry of Agriculture to promote aquaculture.

3. White carp

The white carp (Carassius auratus cuvieri temminck et schlegel) is a species of carp that can be fished in freshwater. It is also known as "Japanese Kawachi crucian carp", "Gengoro crucian carp" or large solitary carp, Osaka crucian carp. Larger, tall, flattened with a pronounced anterior dorsal bulge.

Crucian carp living habits

White carp, like other crucian carp, is the middle and lower layer of fish, most of the time living in the waters, the lower layer, its adaptability is stronger, the change of water temperature, water quality resistance is greater, even if the dissolved oxygen is reduced to milligram liters will not cause death, because its gill organs are more developed, usually out of the water, can still survive for several hours under low temperature conditions.

3. Peng Ze crucian carp: This is a crucian carp species living in Jiangxi Province. It has a plump body, a high meat content, and is rich in nutrients, making it a very suitable ingredient.

4. Heterogeneous silver carp: This variety is a variety cultivated with silver carp as the female parent, mainly used for artificial breeding. Compared with other crucian carp species, they grow very fast, and have better adaptability, have a lower disease rate, and are not easy to die, so in general they are very suitable for artificial breeding.

5. Xiangyun crucian carp: This species is mainly a kind of artificially farmed crucian carp, also known as "engineering crucian carp". Their size is also relatively large, and the individual weight can reach 2 catties; They also grow very fast, are resistant to disease and are very tolerant of low temperatures.

1. Heterogeneous silver carp: Heterogeneous silver carp has obvious parental characteristics, pale pink body color, large scales, and fresher and tender meat than carp. Silver carp, white carp, black carp and heterogeneous silver carp are all used as artificially stocked commercial fish and are cultivated in large quantities.

There is also a kind of sea crucian carp, but the number is scarce in China's territorial waters, and the individual is similar to the silver-gray crucian carp, and the body color is gray and black.

2. White crucian carp (large plate crucian carp): white crucian carp has a long body, a large size, a wide diet, and does not have strict requirements for feed, and can also eat plankton. It grows quickly and is also more adaptable and foraging.

3. Silver gray crucian carp: in the flowing or large area of water, due to the large range of activities and the amount of activity, its body is long; In small still water ponds, the fish body is shorter, wider and thicker due to the small range and amount of activity. In some sandy and gravelly water bodies, silver-gray rivets are accustomed to sand foraging, and the upper collar of their mouth is relatively extended, and the lower collar is relatively shortened, forming a "curved mouth crucian carp".

4. African crucian carp, also known as black crucian carp: now it is a freshwater aquaculture fish cultivated by key scientific research in the world's aquaculture industry, and is known as one of the main animal proteins in the future. It usually lives in fresh water, but can also live in saltwater with different salt content, and can also survive in shallow water in lakes, rivers, and ponds.

5. Abundant crucian carp: Abundant crucian carp, also known as Baihua crucian carp, is a new species of all-female crucian carp cultivated by the Fish Research Laboratory of South China Normal University using fish cell engineering technology. Its body color is light, the shape is well-proportioned and graceful, similar to the body shape of the Northeast silver carp, the body back is between the Pengze crucian carp and the high back carp, the meat is relatively firm, and the taste is fresh and sweet.

6. Heilongjiang silver carp: silver carp is mainly produced in Heilongjiang, Ussuri River, Nenjiang River, Songhua River and other water systems in Northeast China, and Shuangfeng Reservoir in Lizheng County, Heilongjiang Province is the concentrated production area. The scales of the silver carp are silvery-white, shiny, large in length, good in flesh, and the common individual is 0

5～1.5 kg, up to more than 3 kg.
