I would like to ask, what types of crucian carp are there?

Crucian carp is an animal of the family Carassius auratus. It is distributed in rivers, lakes and ponds throughout China and is favored by farmers. Crucian carp is mainly an omnivorous fish that feeds on plants. It likes to travel in groups, chooses food and lives. It has a plump body and a graceful posture that shuttles through the water. The following introduces the types and names of crucian carp. Let's take a look.

1. Xiangyun Crucian Carp

Xiangyun crucian carp, also known as engineered crucian carp, is a complete crucian carp. It is a triploid crucian carp successfully bred by Liu Yun, an academician of the Chinese Academy of Engineering and professor of the Department of Biology at Hunan Normal University. It grows very fast, three times faster than ordinary crucian carp. It has the characteristics of wide food habits, high survival rate, resistance to low temperature and lack of oxygen, and is very suitable for artificial breeding.

2. Hybrid Crucian Carp

Hybrid crucian carp is the offspring of silver crucian carp as the female parent and wild carp of Taihu Lake as the male parent. Its advantages are strong adaptability, fast growth, large size, wide omnivorousness, strong disease resistance and delicious meat. It is very suitable for artificial breeding.

3. Pengze Crucian Carp

Pengze crucian carp is an excellent variety for freshwater aquaculture. It is an omnivorous fish. It has the advantages of strong adaptability, fast growth, strong resistance to adversity, few diseases, and tender meat. In addition, the breeding technology is simple, the management is convenient, the investment is small, and the benefits are good, which is very popular among farmers and consumers.

4. Crucian carp

The high-back crucian carp, also known as the triangle crucian carp in some places, is a dominant species that developed in the Dianchi Lake and its water system in Yunnan in the mid-1970s. It has the characteristics of large individuals, fast growth, and strong reproductive capacity. It is named after its high back. The high-back crucian carp can be called the big brother of crucian carp because it is the largest of all crucian carp species. The largest individual can grow to 6 kilograms. It is also a good breeding variety.

5. Founder Silver Carp

Silver carp is an omnivorous fish that mainly feeds on plants. It has the characteristics of small head, thick back, high meat yield, cold resistance, strong disease resistance, fast growth and large size. Its meat is delicious. It is not only a top-grade freshwater edible fish, but also one of the most popular fish in the aquatic product market.

6. Crucian carp Zhongke No. 3

Crucian Carp Qianchong and Zhongke No. 3 are the third generation new varieties of allogeneic crucian carp. It is an omnivorous fish. It can eat not only zooplankton and planktonic food, but also benthic plants and animals and organic debris. It has a wide range of adaptability to water temperature. It can safely spend the winter all over the country. It grows vigorously at 25-30℃ and has a large appetite.

7. White Carp

White crucian carp, also known as Dagu crucian carp, Osaka crucian carp, Japanese crucian carp, is native to Lake Biwa, Japan, and was introduced to China in 1976. It has a silvery white body, a large body, a hump-like back, a small head, a slender tail, and can weigh up to about 3kg. It is the most common farmed crucian carp in China. Most of the silvery white crucian carps sold on the market are this type of crucian carp.

The above is about the introduction of high-quality varieties of crucian carp fry. There are many varieties of crucian carp. Different varieties of crucian carp have different growth characteristics, but the varieties introduced above are the most popular varieties currently cultivated. You can choose the appropriate variety according to the actual situation.

There are many types of crucian carp, such as high-back crucian carp, Xiangyun crucian carp, mountain crucian carp, etc. Among them, Xiangyun crucian carp is also called "engineered crucian carp" because this type of crucian carp is artificially bred and cannot reproduce.

There are many varieties of crucian carp, including white crucian carp, golden crucian carp, native crucian carp, Xiangyun crucian carp, Pengze crucian carp and so on.

1. Highback Crucian Carp

The high-back crucian carp is a population developed in the Dianchi Lake area of ​​Yunnan in the mid-1970s. It is named for its high back ridge. It is large, fast-growing and reproduces rapidly. A single individual can grow to as large as 3,000 grams, and is not suitable for breeding in the mainland.

2. Founder Silver Carp

The Fangzheng silver crucian carp is native to Shuangfeng Reservoir in Fangxieshuzheng County, Heilongjiang Province. It is a very good variety of silver crucian carp. The back of the Fangzheng silver crucian carp is black-gray, and the sides and abdomen of the fish body are white. A single individual can grow to a maximum of 1.5 kilograms, and is generally around 0.5 to 1 kilogram.

How many types of crucian carp are there? Is it the black crucian carp? The ones sold outside are white crucian carp

Crucian carp belongs to the Cypriniformes, Cyprinidae, and Carassius auratus. It is called river crucian carp in Jiangsu and Zhejiang, crucian carp melon seeds in the northeast, and Xitou fish in Hubei. Crucian carp is widely distributed throughout the country except for the western plateau. Crucian carp has a very strong adaptability and can survive in deep or shallow water, flowing or still water, high temperature water (32°C) or low temperature water (0°C). Even in the strongly alkaline waters with a pH of 9 and the Dari Lake with a salinity of up to 4.5%, it can still grow and reproduce. There are two known species of crucian carp in my country (crucian carp and black crucian carp) and one subspecies (silver crucian carp). Black crucian carp is only distributed in the Irtysh River system in Xinjiang. Crucian carp, which we often call native crucian carp, is almost distributed in rivers, lakes, ponds, reservoirs, swamps, ditches and other large and small water bodies throughout the country, except for the Qinghai-Tibet Plateau and northern Xinjiang where it has no natural distribution. This crucian carp has a strong reproductive capacity, likes to live in groups, is resistant to low oxygen, weak alkaline and weak acidic water, grows fast, and the largest individual is about 600 grams. It likes to live in relatively turbid waters with aquatic plants, complex terrain, and dark and concave junctions. The old saying "where there is water, there is fish" refers to this crucian carp. Because of its wide distribution, I believe that anglers across the country are familiar with it. In natural waters, the output can account for 20% to 30% of the fish catch, and in some waters it even reaches more than 40%. Silver crucian carp is mainly distributed in the Heilongjiang River system, Hulun Lake and Xinjiang Irtysh River. Its economic value is the highest among the three varieties, not only because of its fast growth rate and large individual size, but also because it can be hybridized with other varieties to cultivate new crucian carp varieties with more growth advantages. In recent years, through the unremitting efforts of aquatic workers, some crucian carp varieties with excellent growth traits have been selected and hybridized. In addition, new crucian carp varieties have been introduced from abroad for breeding attempts. 1. Excellent local crucian carp varieties in my country that have been selected and bred 1. 1. High-backed crucian carp. High-backed crucian carp is a dominant species that developed in Dianchi Lake and its water system in Yunnan in the mid-1970s. It has the characteristics of large individuals, fast growth, and strong reproductive capacity. It is named because of its high back. The maximum individual weight is 3,000 grams. It is highly hydrophilic and is not suitable for breeding in the mainland. 2. Fangzheng silver crucian carp. Fangzheng silver crucian carp originated from Shuangfeng Reservoir in Fangzheng County, Heilongjiang Province. It is a better silver crucian carp variety. The back of Fangzheng silver crucian carp is black-gray, and the sides and abdomen are deep silver-white. The maximum individual weight is 1.5 kg, and the general weight is around 0.5~1 kg. 3. Pengze crucian carp. Pengze crucian carp is an excellent crucian carp variety selected and bred by aquatic science and technology personnel in Jiangxi Province. It has delicious meat, high meat content, and rich nutrition. It has a plump body, is easy to transport, easy to temporarily raise, and easy to hook, which is conducive to the listing of live fish. It is also a fish that can be developed for both production and fishing. 4. Qihe crucian carp. Qi River crucian carp is named after the Qi River, a mountain river in northern Henan Province that flows from east to west. The Qi River never freezes all year round. In January and February, the water temperature is still above 10℃, and the riverbed of the Qi River is overgrown with water plants. The excellent ecological environment has created good conditions for the growth and reproduction of Qi River crucian carp. The Qi River crucian carp has tender meat and delicious taste. According to ancient records, Qi River crucian carp, fragrant rice and silk eggs are the three major tributes of the local area. In addition to the above-mentioned excellent crucian carps with great economic value, there are also Longchi crucian carp from [Please do not talk nonsense, words are prohibited] County, Jiangsu Province, Hailar silver crucian carp produced in Hailar area of ​​Inner Mongolia, etc. Their common characteristics are large individuals, tender meat and delicious taste, which are deeply loved by local people. 2. Hybrid crucian carp varieties 1. Heterotrophic silver crucian carp. It is the offspring obtained by artificial mating with Fangzheng silver crucian carp as the female parent and Xingguo red carp as the male parent. The hybrid silver crucian carp grows 2 to 3 times faster than ordinary crucian carp, has strong adaptability, few diseases, and a high survival rate. It can be raised on large water surfaces or in ponds, and is a very good artificial breeding variety. 2. Hybrid crucian carp. The offspring obtained by "hybridizing" the square silver crucian carp as the female parent and the Taihu wild carp as the male parent. Trial breeding shows that it has obvious hybrid advantages, strong adaptability, fast growth, large individuals, wide diet, few diseases, and delicious meat. It is generally welcomed by production units. It is suitable for inner ponds, outer ponds, rivers and lakes, and is a new breeding variety with good economic and social benefits. 3. Xiangyun crucian carp (formerly known as engineering crucian carp). Xiangyun Crucian Carp is a triploid crucian carp bred by bioengineering technology combining cell engineering and sexual hybridization engineering. It has the advantages of complete sterility, fast growth, strong disease resistance, wide diet, easy fishing, low temperature resistance, tender and delicious meat, etc. The fry can reach 500 grams at the end of the year, and the individual can exceed 1000 grams after one year of breeding. When the pond fish is hypoxic and flooded, grass carp and silver carp die, while Xiangyun Crucian Carp is safe. 3. Introduced Crucian Carp Varieties At present, the only foreign crucian carp variety introduced in my country is the white crucian carp, which is native to Lake Biwa, Japan. It is a large crucian carp. The white crucian carp has strong adaptability and can grow and reproduce under adverse environmental conditions. It has a greater tolerance to temperature, water quality changes, low dissolved oxygen, etc. The largest individual is about 1000 grams. There are many varieties of crucian carp on the market. If you need to distinguish between wild crucian carp and farmed crucian carp, you can refer to the following methods: First, look at the individual size of the fish. Generally, farmed crucian carp is listed in a larger size, especially the selected and hybrid varieties, which are more uniform in size. Wild crucian carp are mostly caught or fished in large water bodies. They vary in size and are generally small, usually only half the size of farmed crucian carp. Secondly, look at the body shape of the fish. Farmed crucian carp generally have a ridged back and a wider body, while wild crucian carp have a very obvious spindle-shaped body and a smaller head. Thirdly, you can look at the body color of the fish. Farmed crucian carp have a lighter body color, mostly silvery white on the sides, while wild crucian carp have a light yellow body color and a shiny body surface.
