Culture methods of crucian carp

Crucian carp has delicate meat, delicious taste, high nutritional value, rich in protein and a variety of nutrients, as well as high medicinal value, which has the effect of tonifying deficiency and warming stomach and invigorating vital energy. Crucian carp is widely distributed in China, and it is cultivated all over the country. It is one of the main edible fish in our country. The following pro-agricultural network brings you the breeding methods of crucian carp.

1. Culture preparation

Choose a suitable aquaculture pond, preferably in the leeward to the sun, drainage convenient zone, the pond water emptying, using the sun exposure for a few days, disinfect with quicklime and release water. Choose the species to be farmed. After years of artificial breeding and breeding, crucian carp has produced many new varieties. It is recommended to choose high-backed crucian carp, which is 2-3 times faster than other varieties. Choosing high-quality feed for aquaculture requires that the content of protein should reach more than 30%.

2. Release seedlings

When releasing seedlings, the water temperature should be stable at more than 10 degrees, and too low water temperature will affect the survival rate of seedlings. In order to facilitate breeding and sale, it is necessary to release seedlings at once, and do not release seedlings in batches, so it is inconvenient to breed. Disinfection treatment is carried out before releasing seedlings to reduce the probability of common diseases. Generally, about 2000 seedlings per mu are released, and too dense is not conducive to growth. It can also be cultured with other fish, and the culture effect is more obvious.

3. Water quality management

Crucian carp is rich in calcium and phosphorus, these two substances are 2-3 times that of other fish, so in culture to ensure the content of calcium and phosphorus in the water to meet its growth needs, in about half a month to apply lime solution and calcium phosphate. Other trace elements are also indispensable, so organic fertilizer should be applied according to changes in water quality, and duckweed or Chlorella can be cultivated in the pond if necessary. Pay attention to the change of water quality at high temperature, and change the water in time if the water quality is too bad.

4. Input and feeding management

Crucian carp is a plant-eating omnivorous fish, the choice should be in line with the preferences of crucian carp, feeding a small number of times, 6-8 times a day, each time should not be too much. When the temperature is low in spring, the food intake of crucian carp decreases, which can reduce the feeding times, while the high temperature in summer increases the food intake of crucian carp, which is the period of rapid growth, so it is necessary to increase the feeding quantity and times.

5. Disease control

The main diseases of crucian carp are water mildew, hepatobiliary syndrome and red Gill disease. if these diseases are not treated in time, they will cause the death of crucian carp. It is necessary to regularly sprinkle quicklime for disinfection and sterilization to reduce the possibility of disease.

The above is the farming method of crucian carp brought by the pro-agricultural network for you. I hope this article can help people in need and have more knowledge about aquaculture. Please pay attention to the pro-agricultural network. We will bring you more details.
