Carp breeding technology and fish pond management

Carp has tender meat, delicious taste and rich nutrition, and is deeply loved by consumers. Carp is a bottom-feeding omnivorous fish that likes to live at the bottom of the water body and often forages in the aquatic plants on the soft muddy bottom. It has strong adaptability and vitality. Below, I will introduce carp farming technology and fish pond management , let’s take a look.

1. Fish pond selection

Fish ponds should be located in places with sufficient water resources, good water quality and no pollution, with convenient transportation, and easy management and sales. The pond area is generally 3-10 acres, the water depth is 1.5-2.5 meters, the pond bottom is flat, the bottom is clay or loam, and it has good water retention. The pond needs to have a complete water inlet and outlet system to ensure that the water quality is controllable.

2. Release of fish fry

Choose healthy, disease-free, and neatly sized fry, with the best length being around 5 cm. Generally, 200-300 carp fry are released per acre. If high-density breeding is adopted, 2,000-3,000 or even more fish can be released per acre. It can be raised together with other fish such as black carp, silver carp and bighead carp, with about 300 kilograms per acre, but attention should be paid to the proportion and quantity of the mixed fish.

3. Feed management

Carp is an omnivorous fish and can be fed with plant-based feeds such as fish cakes, shrimps, wheat bran , and bean cakes. It can also be fed with appropriate amounts of animal-based feeds such as chironomid larvae and snails. When the water temperature reaches 10-15℃, feed 0.5%-0.8% of the fish loading amount, twice a day. Feeding needs to be adjusted flexibly according to weather, water temperature, and fish feeding conditions.

4. Water quality management

Regularly monitor indicators such as dissolved oxygen, pH value, ammonia nitrogen, nitrite, etc. to ensure that water quality meets standards. Change the water regularly, maintain the water transparency at 30-40 cm, use quicklime , chlorine dioxide, etc. for disinfection and sterilization, and regularly use microbial preparations to improve the bottom quality.

5. Daily management

Patrol the pond once in the morning and evening every day to observe the fish feeding and activity, and check the water color and quality. Record feeding amount, water quality changes, disease prevention and control, etc. to optimize management. Disinfect ponds and tools regularly, feed fresh feed, and avoid overfeeding.

The above is an introduction to carp farming technology and fish pond management. Carp has a strong reproductive capacity and can lay tens of thousands to hundreds of thousands of eggs at a time. When farming carp, you must pay attention to fish pond management to avoid the occurrence of diseases.
