A Detailed Explanation of Crucian Carp Farming Methods and Technical Key Points

Crucian carp has delicate, tender flesh and a delicious flavor, with high nutritional value. It is rich in protein and various nutrients, and also has extremely high medicinal value, with the effects of tonifying deficiency and warming the stomach, and replenishing the middle and boosting vitality. Crucian carp is widely distributed in China and is farmed throughout the country. It is one of the main food fish in China. Below, Qinnong Web brings you the farming methods for crucian carp.

1. Farming Preparation

Choose a suitable farming pond, preferably in a sheltered, sunny area with convenient drainage. Drain the pond completely, expose it to the sun for several days, disinfect it with quicklime, and then fill it with water. Choose the variety to be farmed. After many years of artificial breeding and selection, crucian carp has produced many new varieties. It is recommended to choose the high-back crucian carp (Carassius auratus), whose growth rate is 2-3 times that of other varieties. Choose high-quality feed for farming, requiring a protein content of 30% or more.

2. Releasing Fry

When releasing fry, the water temperature must remain stable above 10 degrees. Too low a water temperature will affect the survival rate of the fry. To facilitate farming and selling, release all the fry at once rather than in several batches, as batch release makes farming inconvenient. Before releasing the fry, disinfect the seedlings once to reduce the incidence of common diseases. Generally, release about 2,000 fry per mu. Overcrowding is not conducive to growth. They can also be farmed together with other fish species, with fairly obvious farming results.

3. Water Quality Management

Crucian carp is rich in calcium and phosphorus, and these two substances are 2-3 times those of other fish. Therefore, during farming, ensure the calcium and phosphorus content of the water body to meet its growth needs. Apply a lime solution and calcium phosphate about once every half month. Other trace elements are also indispensable, so apply organic fertilizer according to changes in water quality. When necessary, cultivate duckweed or chlorella in the pond. Pay attention to changes in water quality during high temperatures, and replace the water promptly once the water quality becomes too poor.

4. Feeding Management

Crucian carp is an omnivorous fish that feeds on plants. Choose feed that suits the preferences of crucian carp. When feeding, feed small amounts multiple times, feeding 6-8 times a day, and do not feed too much each time. In spring, when temperatures are lower, the food intake of crucian carp decreases, so the number of feedings can be reduced. In summer, with high temperatures, the food intake of crucian carp increases, and this is precisely the period of rapid growth, so the feeding amount and frequency should be increased.

5. Disease Prevention and Control

Disease prevention should be the priority. The main diseases of crucian carp include saprolegniasis, hepatobiliary syndrome, and red gill disease. If these diseases are not treated in time, they will all cause the death of crucian carp. Regularly splash quicklime to disinfect and sterilize, reducing the possibility of disease outbreaks.
