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

1. I would like to ask, what are the types of crucian carp?

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 Zhongke No. 3 is a new third-generation variety of heterologous 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 throughout 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 distinct hump-like back, a small head, and a slender tail. It 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.

Crucian carp is also known as crucian carp, commonly known as crucian carp seeds, moon crucian carp, native crucian carp, thin head, crucian carp, cold crucian carp, happy head, crucian carp shell and river crucian carp.

Crucian carp is an omnivorous fish that mainly feeds on plants. It likes to travel in groups and live in places where it chooses to eat. Its meat is tender and has high nutritional value. Every 100 grams of meat contains 13 grams of protein, 11 grams of fat, and a large amount of minerals such as calcium, phosphorus, and iron. Crucian carp has extremely high medicinal value. It is mild in nature and sweet in taste. It enters the stomach and kidneys and has the effects of harmonizing the middle and replenishing deficiency, warming the stomach to eat, and replenishing the middle and invigorating vitality.

Crucian carp is an omnivorous fish that lives in freshwater. It has a plump body and swims gracefully in the water. Crucian carp is a bottom fish. Generally, it swims, forages and lives underwater. When the air and water temperatures are high, it will also swim and forage in the middle and lower layers and the middle and upper layers of the water.

Adult crucian carp mainly feed on plant-based food. Since plant-based feed is abundant in water bodies and there are many varieties, there is a wide range of food for it. The stems, leaves, buds and fruits of vascular water plants are crucian carp's favorite food. In waters with higher aquatic plants such as water chestnuts and lotus roots, crucian carp can obtain a variety of rich nutrients. Diatoms and some algae are also crucian carp's food, in addition to shrimps, earthworms, young snails, insects, etc.

Nutritional Value

1. The protein contained in crucian carp is of high quality, has a comprehensive range of amino acids, and is easy to digest and absorb.

2. Crucian carp contains a small amount of fat, mostly composed of unsaturated fatty acids.

3. Compared with other freshwater fish, crucian carp has a higher sugar content, which is mostly composed of polysaccharides.

4. Crucian carp is rich in trace elements, especially calcium, phosphorus, potassium and magnesium.

5. The head of crucian carp is rich in lecithin.

The silver-gray crucian carp mainly lives in flowing or large water bodies. Due to its large range and activity level, its body is relatively long. If it lives in a small still pond, due to its small range and activity level, the fish body is relatively short, wide and fat. In some water bodies with a lot of gravel on the bottom, the silver-gray crucian carp is accustomed to panning for food in the sand, so the upper collar of their mouth is relatively elongated and the lower collar is relatively shortened, forming a "curved-mouth crucian carp".

4. African Carp

It is a freshwater farmed fish that is the focus of scientific research and cultivation in the world's aquaculture industry, and is hailed as one of the main sources of animal protein in the future. It usually lives in fresh water, but can also live in salt water with different salt contents, and can also survive in shallow water in lakes, rivers, and ponds.

2. Breeding conditions of Zhongke No. 3 crucian carp

(1) Environmental requirements

① Zhongke No. 3 is a typical bottom fish, especially adapted to growing in water bodies with fertile bottom and rich benthic organisms. It can live in still water and rivers, lakes and reservoirs with a certain flow, and is also suitable for breeding in ponds. It has a wide range of adaptability to water temperatures and can safely overwinter in all parts of the country. The best water temperature for growth is 25-30℃. Within this temperature range, crucian carp has a strong appetite and grows fast.

② The growing period in the Yangtze River Basin is from March to November, with the fastest growth rate from July to September; it has a strong adaptability to the environment, and also has a strong tolerance to physical and chemical factors such as the pH value of the water and low dissolved oxygen, making it suitable for breeding in various water bodies.

(2) Bait requirements

① Zhongke No. 3 crucian carp is omnivorous. The type of food varies with its individual size, season, environmental conditions, and dominant biological populations in the water. Fry under 1.5 cm in length mainly feed on rotifers; young individuals of 1.5-3.0 cm mainly feed on animal food, including algae, rotifers, cladocerans, copepods, chironomid larvae, and other insect larvae; individuals over 3 cm in length until adult fish mainly feed on plant food, such as epiphytic algae, duckweed, and young leaves and buds of aquatic vascular plants.

② Under artificial breeding conditions, they also like to eat barley, wheat, bean cake, corn and compound feed, and also eat natural bait in the water.
