CATDOLL : CATDOLL: Can silver crucian carp reproduce in fish ponds?

1. Can silver crucian carp reproduce in fish ponds?

Can breed, fish breeding eggs do not have to be attached to water plants, can be directly sunk to the bottom of the water, such as naturally bred crucian carp, carp, etc. in the pond. In addition, you can also set up artificial fish nests for fish eggs to attach.

Because crucian carp will reproduce if the conditions and environment in the fish pond are suitable for reproduction.

Can fish reproduce in a pond? Of course they can. If they can survive, they will reproduce.

2. What kind of feed should be used to feed silver crucian carp?

Feed for silver crucian carp:

The silver carp has no preference for food. As long as it is palatable, it can consume all kinds of food. Diatoms, rotifers, cladocerans, copepods, aquatic insects, fly maggots, barley, wheat, bean cakes, corn, rice bran and plant debris are all its favorite feeds. Under artificial breeding conditions, it also likes various commercial feeds.

If you have many fish ponds, you can try various types of feed, record the data, calculate the input-output ratio, and finally determine which feed is the best choice. The best protein for crucian carp is 33 protein-38 protein.

Medium and large feed companies have special crucian carp feeds with 31~36 protein.

3. There are several varieties of crucian carp

There are many varieties of crucian carp, the common ones include Dianchi high-back crucian carp, Fangzheng silver crucian carp, Pengze crucian carp, Qihe crucian carp, heterogeneous silver crucian carp, hybrid crucian carp, white crucian carp, Xiangyun crucian carp, platinum high-yield crucian carp, golden crucian carp, African crucian carp, Jiangsu black crucian carp, etc.

1. Alternative silver crucian carp

The silver carp has obvious characteristics of its parents, with a light pink body color, larger scales, and tenderer meat than carp. Silver carp, white carp, black carp, and silver carp are all artificially raised as commercial fish and are cultivated in large quantities. There is also a sea crucian carp, but it is rare in my country's territorial waters. Individuals are similar to silver-gray crucian carp, with gray-black body color.

2. White crucian carp (Big crucian carp)

White crucian carp has a long body, a large head, a wide range of diets, and is not strict on feed, and can also eat plankton. It grows rapidly and has strong adaptability and foraging ability.

3. Silver-gray crucian carp

In flowing or large water bodies, due to their large range and activity level, their bodies are relatively long; in small still water ponds, due to their small range and activity level, their bodies are relatively short, wide, and thick; and in some water bodies with a lot of gravel on the bottom, silver-gray crucian carp are accustomed to panning for food in the sand, so the upper collar of their mouths is relatively elongated and the lower collar is relatively shortened, forming a "curved-mouth crucian carp".

4. African crucian carp is also called black crucian carp.

Tilapia

Now 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.

5. High-yield crucian carp

Fengchan Crucian Carp, also known as Baihua Crucian Carp, is a new all-female crucian carp variety bred by the Fish Research Laboratory of South China Normal University using fish cell engineering technology. Its body color is light, its appearance is symmetrical and beautiful, and its body shape is similar to that of Northeast Silver Crucian Carp. Its back is between Pengze Crucian Carp and Gaobei Crucian Carp. Its meat is relatively firm and tastes sweet.

6. Heilongjiang Silver Carp

Silver crucian carp is mainly produced in the Heilongjiang River, Wussuri River, Nenjiang River, Songhua River and other water systems in Northeast my country, and the Shuangfeng Reservoir in Lizheng County, Heilongjiang Province is the concentrated production area.

The scales of the silver crucian carp are silvery white and shiny, the body is large and the meat is good. Common individuals weigh 0.5 to 1.5 kg, and the largest can reach more than 3 kg.

7. Dianchi high-back crucian carp

High-back crucian carp has a wide adaptability and can grow in lakes, reservoirs, ponds, dam ponds and other waters. The optimal water temperature for growth is 24-30℃.

8. Founder Silver Carp

It is a specialty of Fangzheng County, Heilongjiang Province. It has the characteristics of small head, thick back, high meat yield, cold resistance, strong disease resistance, fast growth and large size.

9. Pengze Crucian Carp

Pengze crucian carp is native to natural waters such as Dingjia Lake, Taibo Lake, Fang Lake and Yun Lake in Pengze County, Jiangxi Province. It is called reed crucian carp because it often lives among the reeds in the lake and has 5-7 gray-black reed-like stripes on the sides of its body (the stripes will gradually disappear after being raised in the pond for a period of time). It is famous for its large size (the largest individual known weighs 6.75 kg), so it is called Pengze big crucian carp.

10. Qi River Crucian Carp

Qi River crucian carp is produced in the Hebi area in northern Henan. Qi River is the only river in Henan that is not polluted, so Qi River crucian carp has been listed as one of the famous specialties of Qi River and the first of the three treasures of Hebi. Qi River crucian carp has a light brown back, a silvery white belly, a transparent pectoral and tail fin, a broad back, and a plump body. It is commonly known as "double-backed fish". It was listed as a tribute in the Ming Dynasty and is now one of the rare aquatic animals in Henan Province.

11. Xiangyun Crucian Carp

Xiangyun crucian carp is a new triploid fish bred by a research team led by Academician Liu Yun from the School of Life Sciences of Hunan Normal University, using a combination of cell engineering technology and sexual hybridization, after years of dedicated research.

12. Golden Carp

Fins and tail. After generations of selection, breeding, mutation and hybridization, the originally wild golden crucian carp has gradually evolved into a variety of goldfish varieties specially for people to appreciate.

13.Colored Crucian Carp

It was named "Xiji Colorful Crucian Carp" by aquatic scientists. "Xiji Colorful Crucian Carp" has various body colors, including pure white, pure red, pure black, golden yellow, black and purple, etc. There is also a colorful flower crucian carp, which is graceful and beautiful and especially lovable. The living habits of "Xiji Colorful Crucian Carp" are similar to those of silver-gray crucian carp.

Pu'an silver crucian carp, shrunken crucian carp, Jiangsu black crucian carp, Furong carp and so on.

1. Crucian carp

Native crucian carp is relatively rare in the market, so its price is relatively expensive, but it tastes absolutely better than other crucian carp. The body color of native crucian carp is blue-gray, and it is a naturally grown crucian carp, that is, they can reproduce naturally in reservoirs or ponds, and can be regarded as the most authentic wild crucian carp. Native crucian carp is very wild, with a slightly thinner body and a very obvious spindle cone shape, and its intestines are thin and long. The biggest characteristics of this native crucian carp are that it grows fast, has a very strong disease resistance, is a pan-eating food, and is easy to catch. It has a very strong vitality, and it will not die within an hour of leaving the water, unlike other fish.

2. Engineering Carp

The engineered crucian carp is also called Xiangyun crucian carp. Its appearance is no different from that of ordinary crucian carp, and its back is also blue-gray, but it is smaller in size and has fewer internal organs, so its abdomen is relatively smaller than that of other crucian carps. There was no such species as engineered crucian carp in nature, but after a long period of artificial cultivation, a new species was produced by the intersection of crucian carp and carp, so the engineered crucian carp itself has no reproductive ability. Its characteristic is that it grows fast and can easily get close. Its growth rate is also 3 times that of other crucian carps, but it does not taste so good. The disease resistance of engineered crucian carp is very strong. No disease or large-scale death has occurred in ponds or ditches.

3. Highback Crucian Carp

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