Is it true that you can raise black carp in the north?

Black carp can be raised in the north, but it is difficult. The water temperature for black carp to survive is 0.5-40℃. The temperature in the north is too low in winter and it cannot survive. If you want to raise it, you can build a plastic greenhouse on the pond in winter to maintain the temperature.

Black carp, scientific name is snail green, also known as black carp in some places. It is a vertebrate of Cypriniformes and Cyprinidae, distributed all over China, especially in the middle and lower reaches of the Yangtze River and lakes along the river. It is one of the "four major carps" (black carp, silver carp, grass carp and bighead carp) in freshwater farming in my country. Black carp is a large fish, with adult fish weighing 10-30 jin, and the largest individual can reach more than 200 jin.

Black carp is the fastest growing and largest fish among the four major carps. The largest black carp recorded in China is 1.86 meters long and weighs more than 200 kilograms. Scale identification shows that it has lived for 40 years. This shows that black carp is not only large in size, but also has a long lifespan.

How to raise black carp?

1. Fish pond construction

The breeding of black carp should be carried out in places with good water quality, sufficient water circulation and water quality that meets the breeding standards. The setting of the pond also requires smooth drainage and irrigation, good ecological environment, no pollution and abundant feed resources. The breeding area is about 20 mu, the water depth is about 2.3m, and the thickness of the silt in the pond is preferably controlled at about 20cm. It is also necessary to equip one oxygen machine and one feeder for every ten mu.

In winter, the pond water needs to be drained and dried for about 20 days. Then, 20 cm of water should be injected for disinfection, and quicklime water should be sprinkled on it. After the water quality is completely dissolved, add lime water to feed the fish.

2. Seedling selection and breeding

When choosing herring fry, it is best to choose strong, well-proportioned, active fry with good growth and strong physique. Note that fish species introduced from outside need to be inspected and disinfected before they can be put into the pond for free-range breeding. Chlorine dioxide can be used for disinfection. 20

Disinfect with potassium permanganate of about mg, and then disinfect with salt in about 20 minutes, and finally add fish species in the ratio of 8:2.

3. Scientific proportion of bait

Black herring generally feed on aquatic plants and living organisms in the water. When breeding artificially, it is necessary to adopt a scientific bait composition ratio to improve the conversion rate of black herring feed. Do not put in a large amount of food, which will cause the food to accumulate at the bottom of the pond, causing it to rot and deteriorate, affecting the water quality. When building a fish pond, in order to reduce the cost of feeding, you can add some fish grass powder, which can not only meet the special requirements of herring fiber, but also facilitate the healthy and rapid growth of herring.

I think it is possible to raise black carp in the north, but it is more difficult than in the north, because black carp is not suitable for living in a low temperature environment, and a greenhouse needs to be built to keep it warm.

It is true. Now many places go to the north to raise black carp. The climate in the north is also very suitable. The fish raised are also very good.

It’s true. Now many people go to the north to raise fish, and the temperature and weather in the north are also very suitable for raising blue carp.

Black carp can be raised in the north, but it is difficult. The water temperature for black carp to survive is 0.5-40℃. The temperature in the north is too low in winter and it cannot survive. If you want to raise it, you can build a plastic greenhouse on the pond in winter to keep the temperature low.

Can black carp reproduce on its own? Why can't it reproduce on its own?

Black carp is a common freshwater fish, and they can reproduce on their own. Wild black carp generally reproduce on their own. They reproduce from May to July every year, when the climate is most suitable. Artificially bred black carp can sometimes reproduce on their own, but the chance is not high. Moreover, the hatching rate when they reproduce on their own cannot be guaranteed. Therefore, when breeding, artificial breeding is usually used to breed black carp. 1. Can black carp reproduce on its own? Black carp is a relatively common freshwater fish, and they have both wild and artificially bred varieties. Black carp can reproduce on its own. For example, the breeding time of wild black carp is generally concentrated in May to July every year. During this stage, the temperature is relatively suitable. At this time, female black carp that have reached sexual maturity will lay eggs in the river state and reproduce. Sometimes we can also observe male and female fish chasing and fighting each other. In the Yangtze River and the Pearl River, the number of black carp eggs is very large. Artificially bred black carp can sometimes reproduce naturally.

However, it should be noted that the hatching rate of herring eggs is not particularly high if they reproduce on their own, and many eggs cannot be hatched. Therefore, generally speaking, herrings are artificially hatched when they are raised artificially, which can ensure the hatching rate and yield.

2. Why can't black carp reproduce on its own? As mentioned above, black carp can reproduce on its own. Wild black carp generally reproduce on their own. Their reproduction period is from May to July every year. During this period, the temperature is most suitable. Black carp can also reproduce on their own when raised artificially, but considering that the hatching rate cannot be guaranteed if they reproduce on their own, breeders generally choose to artificially breed black carp and hatch black carp eggs. Under artificial conditions, it is easier to ensure a suitable environment, especially temperature, so that the success rate of reproduction is high, the yield can be better guaranteed, and higher economic benefits can be obtained.
