CATDOLL : CATDOLL: What is the common name of black carp?

1. What is the common name of black carp?

Black carp is one of the important freshwater fish in my country and belongs to the genus Black carp of the family Cyprinidae.

Black carp is a very common freshwater fish in my country. It mainly lives in the middle and lower waters. It has a long body and a large size. Its dorsal fin is above its pelvic fin and is straight on the outside. Its body is blue-gray in color, with a slightly darker back and a grayish-white belly. Black carp is mainly distributed in China, Vietnam, Austria, the Czech Republic, Malaysia, the United States and other places. It is one of the four traditional freshwater fish in my country.

Black carp is a carnivorous fish that mainly feeds on mollusks living at the bottom of the water. It especially likes snail pupae, so it is also called snail master black carp. Black carp has teeth, and its teeth are relatively sharp, which can bite the hard shells of shellfish such as snails and mantises. It is very greedy. Black carp has now been listed as a world protected animal.

How to raise black carp is as follows:

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 ponds also requires smooth drainage and irrigation, good ecological environment, no pollution and abundant feed resources.

The breeding area is about 20 acres, the water depth is about 2.3m, and the silt thickness in the pond is best controlled at about 20cm. An oxygen machine and a feeder are required for every ten acres.

In winter, you need to drain the water in the pond, expose it to the sun for about 20 days, inject 20cm of water for disinfection, sprinkle in quicklime water, wait until the water is completely dissolved, and then add water to raise fish.

2. Seedling selection and breeding

When selecting black carp fry, it is best to choose strong, well-proportioned, lively and active fry. These fry have better development ability and physique and are stronger. Note that if the fish species introduced from outside need to be inspected and disinfected before they can be put into the pond for free-range breeding.

You can use chlorine dioxide to disinfect by soaking, or you can use about 20 mg of potassium permanganate, which usually takes about 30 minutes to disinfect, or you can use salt to soak for about 20 minutes to disinfect. Finally, you can release the fish in a ratio of 8:2.

3. Scientifically proportioned bait

Black carp generally feed on edible aquatic plants and active organisms in the water. When breeding them artificially, we need to use scientific and reasonable proportions of bait ingredients to improve the conversion rate of black carp feed. We should not allow large amounts of food to accumulate at the bottom of the pond, causing it to rot and deteriorate, thus affecting the water quality.

When building a fish pond, in order to reduce the breeding cost, we can add a certain amount of fish grass powder, which can not only meet the special requirements of black carp for black carp fiber, but also is conducive to the healthy and rapid growth of black carp.

2. Is herring a freshwater fish or a marine fish? Is herring a freshwater fish?

Black carp, grass carp, silver carp and bighead carp are collectively known as the "four major carps". Black carp is one of the four major carps and is easy to breed. Since it is domesticated, it is a freshwater fish. Black carp is large in size, delicious in taste and rich in nutrition.

What is black carp?

Black carp is a green fish that is mainly distributed in the plains south of the Yangtze River in my country and is relatively rare in the north of the Yangtze River. It is an important fishery resource in the middle and lower reaches of the Yangtze River and the lakes along the river, and the main breeding object in lakes and ponds. It is one of the "four major carps" in my country's freshwater farming.

Is herring a freshwater fish or a marine fish?

Black carp is a freshwater fish. Why? Because it is an important fishery resource in the middle and lower reaches of the Yangtze River and the lakes along the river, and the main breeding object in various lakes and ponds. It is one of the "four major fishes" in freshwater breeding in my country, so black carp is a freshwater fish. Black carp is large in size, delicious in taste, and rich in nutritional value.

What is the nutritional value of black fish

Black carp is a high-protein, low-fat food, with a protein content of 20.1% and a fat content of 4.2%. In the amino acid composition, it is rich in glutamic acid, aspartic acid and other umami components, so it tastes delicious. Black carp is large and thick, fat and delicious, with large and few bones. It contains sugars, multiple vitamins and minerals such as zinc, calcium, phosphorus, iron, magnesium, etc., and is a top-quality freshwater fish. Black carp is rich in lysine, which is generally lacking in people's daily staple food. Therefore, eating black carp regularly can play a complementary role in protein and improve the nutritional value of food.

Five conditions for herring farming

1. Pond conditions: The water quality must be excellent.

2. The fish are raised in a healthy and strong physique.

3. Breeding and management, palatable and fresh.

4. When it comes to fish disease control, prevention is the priority.

5. Catch at the right time, and you can catch black carp when it is larger than 1 kg.

3. How to feed one-year-old black carp

Here’s how:

1. First use a small amount of fine feed to lure the black carp to the feeding table, then feed bean cake slurry twice a day. When it grows to 5cm, mix it with vegetable cakes. When it grows to 7cm, switch to soaked vegetable cakes or bean cakes. When it grows to 10cm, mix it with crushed snails.

2. Follow the "four determination" principles when casting bait:

①Fixed point: feeding table or feeding area.

②Regular time: twice a day, 8-9 am and 2-3 pm.

③Quality determination: Provide high-quality and fresh bait according to different growth stages.

④Quantity: Each feeding should be completed within 1.5 hours. The monthly feeding amount accounts for the proportion of the total feeding amount: 4% in June, 15% in July, 23% in August, 25% in September, 15% in October, 10% in November, 4% in December, and 4% from January to March.

3. Clean and disinfect the feeding area regularly to keep it clean, and remove overnight fish food in a timely manner.

Notice:

Black carp farming is mainly distributed in the plain areas south of the Yangtze River, such as Anhui, Hubei, Huzhou, Zhejiang, and Wuxi, Jiangsu. The farming volume north of the Yangtze River is small. In Anhui, black carp is commonly known as snail mix, black mix, black mix, etc. In Zhejiang, it is commonly known as black carp and snail green, because of its black body and love to eat snails.

Because black carp has thick back meat, fine texture, short fibers and few bones, after the winter solstice every year, a large number of black carp are put on the market in Jiangsu, Zhejiang and Hubei regions, and they are in large sizes of more than 8 jin. The larger the size, the higher the price. Large-sized black carp is usually processed into pickled fish, which is a must-have delicacy for gifts during the New Year and high-end banquets.

Black carp is the only species of the genus Black carp in the subfamily Cyprinidae of the order Cypriniformes. It is slightly cylindrical and relatively large in size. Black carp mostly inhabits the middle and lower waters and is a mild carnivorous fish. Under natural breeding conditions, it mainly feeds on snails and bivalve mollusks, small fish, shrimps, and aquatic insects. Artificial breeding is now the main method, and the main feed is special compound feed for black carp.

When the black carp reaches 15cm in length, the crushing function of the pharyngeal teeth is enhanced, and the feeding habits will change. Black carp grows fast, and a 2-3 winter-old fish can generally reach 7-10 jin. In 2005, the largest black carp ever recorded was caught in Jinniu Lake, Liuhe District, Nanjing. It weighed 218 jin and was 1.86 meters long. It was identified as about 40 years old.
