Culture techniques of mud carp

Mud carp is a tropical or subtropical freshwater fish, commonly known as mud carp, mud carp can adapt to fertile water environment, and strong appetite, strong disease resistance, high yield, but also low dissolved oxygen in water, is a necessary species of fat and water fish ponds. So how to cultivate mud carp? Let's take a look at its farming skills.

1. Fish pond preparation

Prepare a pond with an area of 5-8 mu, the water level is 1.2m-1.5m deep, the silt of the pond should not exceed 20cm, if it is too deep, it is necessary to clean up the mud, requiring clear water quality without pollution and convenient drainage and irrigation. The water in the fish pond should be emptied 3-5 days before seeding. After exposure to the sun, 2-3 kg of bleach per mu should be used for pond cleaning and disinfection.

2. Fish fry restocking in separate ponds

The release time is from June to October, which can be divided into three stages, and the release time can be selected according to the local listing time. The first stage is from the end of June to the beginning of August. The stocking specification is about 5000 tails per kilogram, 40-50 000 tails per mu, and about 120 tails per kilogram when coming out of the pond. About 300kg per mu In the second stage, from August to early September, the stocking specification is 1000 per kilogram, 10 thousand seedlings per mu, about 50 per kilogram per kilogram when coming out of the pond, and 150kg per mu; in the third stage from September to early October, the stocking specifications are 150,250 per kilogram, 2000-300per mu, 1-2 per mu and 500,600kg per mu.

3. Water quality management

It is appropriate to use clear water within one week after the fry is put into the pond. Fertilizer and water should not be used directly. The water level should be controlled in 80cm. Fertilizer can be applied after a week to increase the fertility of the water body. Generally, chicken manure is 5-7.5kg per mu, and the whole pond is sprinkled evenly, waiting for the transparency of the pond water to be 25-30cm. Under the normal growth of fish fry, water is generally injected once a week, and the water temperature is controlled at 1.2m-1.5m.

4. Feeding management

Fish fry after entering the pond, the body is less, the feed is mainly soybean milk, supplemented by vegetable cake, sprinkle soybean milk twice a day, supplemented by a small amount of vegetable cake, wait for fish fry to grow for 7-10 days, wait for fish fry on the beach, you can plant milk on the foot of the beach. The fry after the division of the pond should apply organic fertilizer according to the quality of the bottom. Generally, 100-150 kg of red worms per mu should be fed as the opening material, and vegetable cakes should be fed, and 1.5 kg of vegetable cakes should be consumed for every 1 kg of mud carp.

5. Disease control

Mud carp has strong disease resistance, but it is very easy to get bubble disease during the fry period, so in order to do a good job in the prevention of bubble disease, we must first put clear water into the pond and regularly inject fresh water to keep the water quality clear. In addition, the prevention and treatment of parasitic diseases can be sprinkled with Baicongjing whole pool, and then sprinkled with fish frog rotten skin Zhixue Ling whole pool the next day, the effect is excellent.

The above is the culture technology of mud carp. I hope it can help you. If you want to know more about fish culture, please follow us.
